How I Built 6 Family Apps With Base44 (No Coding, Every Prompt Included)

BLUF: I built six family apps in Base44 with no coding, using prompts Claude wrote from my ideas: 56 prompts, about two and a half hours of total build time and roughly 112 credits. That's a little more than one month of Base44's Starter plan ($20 for 100 credits), and about 15 of those credits Base44 never actually charged me for. Every starting prompt is below, ready to copy.

I'm not a developer. I'm a dad with four kids, two houses and a fridge covered in paper that never quite keeps up. So I started describing the tools I wished existed to Claude. Claude wrote a detailed build prompt, I checked it against what my family actually needed, and then I pasted it into Base44 to build.

I logged every prompt as I went: what I typed, how many credits it used, how long it took, and whether it worked. This post is that log, cleaned up. You'll get the exact starting prompt for all six apps, what went wrong, the one-line fixes that got each one working, and what it takes to keep them safe and running.

The six apps at a glance

The first build of every app took 11 minutes or less and used one credit or less. The bigger numbers come from going back later: a full holiday planner for Two House Hub, upgrades for Sleeps Until and Gratitude Jar so the apps match their paper versions, and a long run of additions to Family Light, from a night sky to Bible verses.

Minutes are the time Base44 spent building, not the time I spent thinking up the idea or testing it on the fridge. Base44 didn't charge credits for Family Light's later prompts, so I've counted those at about what they should have cost.

How I build every app, step by step

Every app followed the same eight steps. The big first prompt does most of the work; everything after it is small fixes.

1. Write down the problem in your own words.
   Before doing anything else, I write one sentence about what's annoying at home. "I never know which house the water bottles are at" became Two House Hub.
2. Copy my prompt, or revise it with Claude for your specifics.
   Start from one of my starting prompts below and paste it straight into Base44. To tailor it first, paste it into Claude and tell it what's different for your family: your kids' ages, your schedule, what you'd add or skip. It will rewrite the prompt to fit. Starting from your own idea instead? Describe how it should work and feel, like "no leaderboards" or "no guilt if they miss a day," and ask Claude for a detailed Base44 build prompt.
3. Check the prompt before you paste it.
   This is your job, and it's the step that matters most. Read it like you're the one using the app: is anything missing, wrong for your family, or more than you need? Ask Claude to fix it, then copy and paste it into Base44.
4. Ask for sample data and a "Clear sample data" button.
   Sample data lets you test right away. The clear button saves you a fix later; three of my six apps needed one added after the fact, and a fourth needed its button fixed.
5. Ask for a login in the first prompt.
   The login is your safety net if the app's link ever gets out (more on that in Logins below). I added logins afterward on three apps, and each one took an extra prompt. Saying it up front is cheaper.
6. Click through everything in the preview.
   Tap every button the way your kid would. Write down what's broken or ugly.
7. Hit a problem? Take it to Claude first.
   Describe what's wrong to Claude in your own words (a screenshot helps) and ask it to write the fix prompt for Base44. Then paste that in, one fix at a time. Simple ones you can type yourself: "The home screen is blank" fixed a blank screen first try. If Base44 shows an error message, try its built-in "Resolve with AI" button first; it fixed a crash for me for 1 credit.
8. Install it.
   Open the published app on your phone or tablet and add it to your home screen. On the fridge tablet it runs full screen like a normal app.

The six apps and the prompts I used

Each starting prompt below was written by Claude from my rough idea, checked by me, and pasted into Base44 exactly as you see it, apart from one kid's name I swapped out. These are my originals, warts and all: some are missing the login or sample data I only learned to ask for later. Want versions with all of that built in? They're in the free prompt pack.

1. Two House Hub

What it does: A custody calendar where each night is colored by house, a tracker for water bottles, shoes and uniforms, an auto-built packing list for every handoff, and a holiday planner for alternating years, split days, holiday trades and school breaks.

How the build went: The original build took 11 minutes and 0 credits, and one design tweak fixed the part I didn't like. Later I added the holiday planner with one big prompt: 6 credits and 6 minutes. Testing it end to end turned up nine more fixes, from holiday trade groups to the print layout. One of those changes crashed the agreement screen, and Base44's "Resolve with AI" button fixed it for 1 credit. That's why this app has the biggest numbers above.

Starting prompt:

Build a mobile-first web app called "Two House Hub" for a parent whose kids split time between two homes. It has two connected parts: a custody calendar and a stuff tracker. The design should be clean, calm and simple, with big tap targets, usable one-handed on a phone. Bottom tab bar: Calendar, Stuff, Pack.

SETUP
- The parent names the two homes (default "Dad's" and "Mom's") and picks a color for each.
- Kids are added by first name or nickname only, each with a color. Do not collect any other information about the kids (no birthdays, photos, schools or ages).
- Login required; all data is private to the account.

CALENDAR (home screen)
- Month view where each NIGHT is colored by which house the kids sleep at.
- Tap a night to flip it to the other house. Press and drag across nights to set a range at once.
- Pattern generator: choose a pattern (week on/week off, 2-2-3, 2-2-5-5, or a custom repeating sequence), a start date and which house starts, then fill forward a chosen number of months. Manual edits override the pattern and show a small dot.
- A handoff is wherever the house changes between consecutive nights. Each handoff can have an optional time and note.
- Top banner: "Next handoff: [day, time] → [house]".
- Stats bar: nights at my house this month and this year, the percentage split, and my next stretch without the kids (start date and number of nights).
- Nights without the kids are shaded lighter so gaps are obvious.
- Year view toggle: 12 mini months on one screen, same colors, so gaps across the year are easy to spot.

STUFF TRACKER
- Item fields: name, kid (or "Shared"), category (Water bottle, Shoes, Uniform, Charger, Meds, Comfort item, School, Other), current location (House A, House B, School, Lost), optional "needed at" house + date, optional note.
- Main list grouped by location with counts, filterable by kid and category.
- Changing an item's location takes one tap (a quick picker) and is timestamped, e.g. "Moved to Mom's · Tue".
- Warnings: if an item is needed at a house on a date but is currently at the other house, and a handoff happens before that date, it appears on the Pack list. If no handoff happens in time, flag it red: "Won't be there in time."

PACK (handoff checklist)
- Auto-built checklist for the next handoff: every item that needs to travel, grouped by kid.
- Checking an item off moves it to the destination house.
- Button to add a one-off item to this handoff's list.

Start with realistic sample data (two made-up kids, a 2-2-5-5 schedule for the next three months, about 12 items) so I can test immediately, plus a "Clear sample data" button in settings.

2. Gratitude Jar

What it does: One shared jar on the fridge tablet. Anyone taps their avatar, writes a short note, and watches it drop in. There's a dinner mode for our butterflies and pickles, and a small thank-you mission for everyone each day. When the jar is full, you open it together and read the notes aloud.

How the build went: 5 minutes and 0 credits for the first build. I then asked for a login, a way to add family members, and to drop the PIN, which partly worked. One more prompt ("fix the clear sample data button to actually function") finished it. Later I upgraded it to match the free dinner prompts and the paid Gratitude Jar Maker: dinner mode, a name and open-on date for each jar, and prompts and thank-you missions about our own people. Testing turned up two bugs, a hidden "Stuck?" button and a jar that never moved to the shelf, and each took one short fix. The personal prompts come from my paid maker, so that one prompt isn't in the free pack.

Starting prompt:

Build a mobile-first web app called "Gratitude Jar" for a family to use together on one shared device (a phone or a tablet on the fridge). Warm, playful design with soft colors and big tap targets.

SETUP
- Add family members by first name, each with a color and an emoji avatar. No other personal info.

HOME
- A large illustrated glass jar in the middle of the screen. Each note appears inside it as a small folded paper slip in the author's color. The jar visibly fills as notes are added (set capacity, default 50).
- Big "Add a note" button.

ADD A NOTE
- Tap your avatar, then type one short note (max 140 characters) or tap a prompt to get started: "Someone who helped you today", "Something that made you laugh", "Something you're proud of", "A favorite moment today".
- Short drop animation into the jar.

OPEN THE JAR
- When the jar is full, or when the parent taps "Open jar" (optionally on a set date), show notes one at a time in random order, full screen, with the author's avatar and the date, and Next / Previous buttons for reading aloud.
- After opening, archive the jar with a name (default: month and year) and start a new empty jar.

PAST JARS
- A shelf of archived jars. Tap one to reread its notes.
- Simple stats per jar: total notes, notes per person.

RULES
- No streaks, no "you missed a day" messages.
- Parent settings behind a simple 4-digit PIN: edit members, jar capacity, delete a note.

Start with sample data (a family of four with made-up names, a half-full jar, and one archived jar) plus a "Clear sample data" button in settings.

3. Others First

What it does: Kids log each act of service in three taps, and each one plants a flower in a shared neighborhood garden. The whole family works toward one goal and a celebration, with no leaderboard.

How the build went: 5 minutes and 1 credit. It worked, but the drawn garden looked flat. I had Claude redesign the garden and flower images, uploaded them, and gave Base44 exact positions for each plot. Base44 only takes 10 attached files at a time, so the last two images went in a second prompt. Then I added a login with one more prompt.

Starting prompt:

Build a mobile-first family app called "Others First" that teaches my kids to value others above themselves by serving people, and tracks each act of service as a flower planted in a shared garden scene.

PURPOSE AND TONE
- Audience: a dad and his kids (roughly ages 6–14). Kids log their own acts, so everything must be simple, big-buttoned, and readable for young readers.
- Warm, hopeful, and playful, but not babyish. Plain, friendly wording.
- Header verse under the title: "In lowliness of mind let each esteem other better than themselves." – Philippians 2:3
- IMPORTANT: No leaderboards, rankings, or "who has the most" counts. The family works together toward one shared goal. Serving should never become a competition.

MAIN VISUAL: THE GARDEN (home screen hero)
- A charming illustrated neighborhood scene (flat, storybook style) with six garden plots, one for each kind of person served:
  1. Family (window boxes and porch planters at our house)
  2. Friends (a friend's front yard)
  3. School (flower beds by the school)
  4. Neighbors (the yard next door)
  5. Strangers (a public park or sidewalk strip)
  6. Church / Community (beds outside a community building)
- Each act of service plants one flower in the matching plot. The flower's petal color is the kid's color. Vary the flower shapes (daisy, tulip, sunflower, poppy, bluebell) so the garden looks natural. Place flowers in each plot with slight random offsets so they don't look like a grid.
- When a new act is saved, animate the flower growing: sprout, then stem, then bloom (about 1.5 seconds). Respect reduced-motion settings.
- Tapping any flower opens a small card showing the story: kid's name, what they did, who they helped, the date, and their "how do you think they felt?" answer.
- Plots with more flowers get a little fuller and livelier (e.g., a butterfly appears at 5+ flowers in a plot).
- Next to or below the scene: "18 of 30 flowers" progress toward the season goal, plus the family celebration reward text (e.g., "When the garden is full: pancake night").
- A small legend of kid names with their colors.

DATA (entities)
- Kid: name, color (hex; assign from a friendly palette of 8 distinct colors), active (boolean).
- Season: number, goal (number of flowers, default 30, range 5–100), reward (text), start_date, is_current (boolean), completed_date.
- ServiceAct: kid (Kid), who_category (family | friend | school | neighbor | stranger | community), what (short text, required, max 120 chars), felt (optional text, max 200 chars), season (Season), created_date, flower_type (assigned at random when created).

SCREENS
1. Home (Garden)
   - Title, verse, the garden scene, progress toward the goal, reward text.
   - Big primary button: "I served someone".
   - "Today's way to serve" card: one service idea per day (rotate from a list), with buttons "We did it" (opens the log flow with the idea prefilled as "what") and "Show another".
   - "Dinner question" line that changes daily (rotate from a list).
   - "Our kindness stories" feed: most recent 30 acts in the current season (kid color dot, what they did, "Name helped [who]", date, felt answer in italics).

2. Log a kindness (a 3-step flow, big tappable buttons, one question per screen)
   - Step 1 "Who served?": buttons for each active kid, showing their color.
   - Step 2 "Who did you help?": six buttons for the categories above, each with a simple icon.
   - Step 3 "What did you do?": short text box plus quick-pick chips ("Helped with a chore", "Shared something", "Said something kind", "Made a card", "Helped a sibling", "Let them go first"). Then optional "How do you think they felt?" text box.
   - Final button: "Plant a flower". Return to the garden and play the growing animation in the right plot.

3. Family setup (for Dad)
   - Add, rename, recolor, or deactivate kids.
   - Set the season goal and the celebration reward.
   - "Start a new garden" button: closes the current season (keeps its history) and starts a fresh, empty garden.
   - Past seasons list: tap one to see that finished garden and its stories (read-only).

4. Garden full celebration
   - When the flower count reaches the goal, show a full-screen celebration (confetti of petals, "Our garden is in full bloom!", the number of kindnesses, the reward), with buttons "Start a new garden" and "Not yet".

CONTENT LISTS

4. Family Light

What it does: A family prayer journal. Kids tap their name, add a prayer in a few taps, and mark it answered with a note about how God answered. Every answered prayer adds a star to a night sky, and when a sky fills up, a new one starts. Prayers can be for one person or for everyone, a "We prayed this" button counts each time the family prays one together, and you can tag any prayer or answer with Bible verses that open with a tap.

How the build went: 5 minutes and 1 credit for the first build. This was my bumpiest one after the build: asking for a login partly worked, and a separate "clear seeded data" button broke something. What fixed it was asking for the whole thing at once: "there needs to be a settings screen with clear sample data, parent login and the ability to add family members." Lesson learned: describe the screen you want, not one button at a time.

After that I kept adding to it, 15 more prompts in all: dates on every prayer, the night sky that fills with stars, prayers for the whole family, the "We prayed this" counter, filters by person and category, and custom categories with their own icons. Almost all of them worked first time. The one that took a conversation was Bible verses. I asked for a "scripture component," Base44 suggested typing out references, and it only clicked when I said what I wanted to happen: type a reference, and the verse text shows up. It built a King James lookup (public domain, so no licensing worries) in one prompt, and three small follow-ups made verses collapse to just the reference, allowed several per prayer, and let me add them to old prayers.

Base44 didn't charge me credits for those later prompts, which was odd, so the numbers above count them at about what they should have cost.

Starting prompt:

Build a simple, warm family prayer journal app for a dad and his kids (some as young as 8). Use one shared family account with member profiles instead of separate logins, so kids can tap their name to use it.

DATA
- FamilyMember: name, avatar emoji, color, role (parent or kid)
- Prayer: request text, prayed_by (FamilyMember), prayed_for (free text, e.g. "Grandma"), category (Family, Friends, School, Health, The World, Thankfulness), date_added, status (Praying or Answered), date_answered, answer_note, is_private (only visible to the person who added it and parents)

SCREENS
1. Prayer Wall (home): open prayers as large, colorful rounded cards showing who prayed it, who it's for, the request, and "praying for X days." Filter chips at top for each family member and category. Big "+ Add a Prayer" button.
2. Add Prayer: step-by-step and kid-friendly. Tap your avatar, type who it's for, type the prayer, pick a category from big icon buttons, save. Minimal typing, large touch targets.
3. Mark Answered: on any card, an "Answered!" button opens a short prompt: "How did God answer this?" with a text box. On save, show a gentle celebration animation and move the card to Answered.
4. Answered page: gold cards showing the request, the answer note, and how many days it took. At the top, a night-sky illustration where each answered prayer adds a glowing star, with a count like "23 answered prayers."
5. Pray Together mode: full-screen, one open prayer at a time with a "Next" button, for family prayer time at dinner or bedtime. Option to shuffle or go person by person.

DESIGN
Soft, calm colors (deep navy for night sky, warm gold for answered, gentle pastels for open cards). Rounded friendly font, large text, readable by an 8-year-old. Mobile-first. No clutter, no ads, no social features.

5. Sleeps Until

What it does: A countdown board for the fridge tablet that counts in sleeps, not days, so kids who can't read dates still get it. Close events show a row of moons, farther ones a progress bar, and tapping a card reads it out loud. A photo can hide behind the countdown and come together one piece each morning.

How the build went: This one took 10 prompts and 22 credits, because I kept tinkering and later upgraded it, not because it was hard. The first build came back with a blank home screen. Typing "the home screen is blank" fixed it in one go. After that I swapped the moon graphic ("looks less like a banana"), added a big focus view with a circular progress ring, and adjusted the ring's colors twice until 0% sat at the top. Later, one big prompt brought it up to match the paper Countdown Maker: the photo that builds itself, halfway and one-week moments, and a choice of how each countdown counts. Base44 paused partway and asked me to type "continue." Then the moons came out looking like yellow cheeses. Describing a crescent didn't fix it, but pasting in the exact picture code did, for 1 credit.

Starting prompt:

Build a family countdown board app called "Sleeps Until" for a wall-mounted tablet on our fridge. It is used mostly by young kids, including ones who can't read or tell time yet, so every countdown must be understandable from pictures alone. Design for landscape, always-on, touch only, with big tap targets and almost no typing for kids.

LOGIN
- The app uses one shared family login. Everyone who uses it signs in with the same account, on the fridge tablet or on a phone.
- The fridge tablet stays signed in permanently and never times out. After a restart it returns straight to the board.
- Changes made on any device show up everywhere within a few seconds, with no refresh needed.

CORE IDEA
Kids don't understand "days," but they understand "sleeps." Every countdown is shown as sleeps, not days or dates. A sleep is crossed off automatically each morning at 6am.

MAIN SCREEN
- Show countdown cards in a grid of 3–6 cards, sorted soonest first.
- The next upcoming event is a large "hero" card at the top.
- Each card shows:
  - A big emoji or uploaded photo for the event (cake, airplane, house, pumpkin, grandma's face)
  - The event name in large friendly text
  - A big number of sleeps plus a moon icon ("5 🌙")
  - The visual countdown described below
- Tapping a card reads it aloud with text-to-speech, for example "Five more sleeps until Maya's birthday!", so non-readers can use it on their own.
- A "+" button in the corner adds a new countdown, and each card has a small pencil icon to edit it. A gear icon opens settings. All editing works directly on the fridge tablet.

VISUAL COUNTDOWN (pick the style automatically based on how far away the event is)
- 14 sleeps or fewer: show a row of moon icons, one per sleep. Sleeps already passed show as a check mark or a sun. Remaining sleeps show as moons. Kids can count them.
- 15–60 sleeps: show a path or road progress bar with a small character (the kid's chosen animal) walking toward the event icon at the end. The bar fills from when the countdown was created to the event date.
- More than 60 sleeps: show a jar slowly filling with colorful marbles, with a label like "a long way away." Don't show large numbers kids can't grasp.
- "Tomorrow!" gets a special glowing card with one moon left and a bouncing icon.

EVENT DAY
- On the day of the event, the card turns into a celebration card: confetti animation, the words "TODAY!", and the event icon large. Play a short cheerful sound the first time anyone taps it that day.
- The day after, move it to a "Done" area that fades away after 3 days. Recurring events reset automatically.

KIDS
- A row of kid photo buttons along the bottom (4 kids). Tapping a kid filters to their countdowns plus family-wide ones. An "Everyone" button shows all.
- Each kid has a favorite color and animal character, which is used on their progress paths.

EDITING (on the tablet or a phone, same screens)
- Add, edit, or delete countdowns with: name, date (with a big easy date picker), emoji or photo upload (including taking a photo with the tablet camera), which kids it applies to (or everyone), and a repeat option (none, yearly, weekly, every other week).
- Yearly repeat is for birthdays and holidays. Every-other-week repeat is for house swap days.
- Manage kids: name, photo, color, animal.
- Settings: the morning cross-off time (default 6am) and night mode hours.
- Editing screens should also use big touch-friendly controls so they're easy to use standing at the fridge.

VISUAL STYLE
- Warm, playful, uncluttered. Soft rounded cards, cheerful but not neon colors, a large rounded font (like Nunito or Baloo).
- Night-sky accents for moons, a sunny yellow for check marks.
- Gentle animations only: a moon flipping to a check mark each morning, the character taking a step forward, confetti on event day.
- Optional dim night mode from 8pm to 6am so it's not bright in the kitchen at night.

TECHNICAL
- Update automatically at the cross-off time without needing a refresh.
- Work well as a full-screen web app on a tablet, and as a normal mobile web app on phones.

6. Bookshelf

What it does: A family reading log for the fridge tablet. Kids tap their emoji, pick a book by its cover photo, and log minutes with a timer or big tap blocks. Every finished book adds a colored spine to their own illustrated bookshelf.

How the build went: My smoothest build. The first prompt worked first time in 5 minutes for 0 credits, because by app six I'd learned to ask for everything up front. Three tiny follow-ups (a clear-data button, cover photos not showing, and one line of empty-shelf text) each worked first time.

Starting prompt:

Build a family reading log app called "Bookshelf" for a wall-mounted tablet on our fridge. It is used by kids of different ages, including ones who can't read yet and are read to, so logging reading must work with pictures and taps alone. Design for landscape, always-on, touch only, with big tap targets and almost no typing for kids.

LOGIN
- The app uses one shared family login. Everyone signs in with the same account, on the fridge tablet or on a phone.
- The fridge tablet stays signed in permanently and never times out. After a restart it returns straight to the home screen.
- Changes made on any device show up everywhere within a few seconds, with no refresh needed.
- All editing works directly on the fridge tablet.

HOME SCREEN
- Big kid buttons across the screen (4 kids). Each button shows the kid's emoji avatar large on a circle in their favorite color, their name, a small version of their bookshelf, and their reading streak.
- A family goal bar along the bottom (see Family Goal below).
- A gear icon opens settings.

LOGGING READING (the main kid flow, 3 taps or fewer)
1. Kid taps their emoji.
2. Kid taps a book from their "Reading Now" shelf, which shows big book cover pictures. A "+" button adds a new book.
3. Kid logs time in one of two ways:
   - Start a reading timer: a big friendly sand-timer or filling-circle animation that runs while they read, with a big Stop button. Minutes are saved automatically.
   - Tap minute blocks: big colorful blocks of 5, 10, 15, and 20 minutes to log reading already done. Blocks can be tapped more than once to add up.
- Also let them choose "I read it" or "Someone read to me" with two big picture buttons, since both count.
- Keep the kid's emoji and color visible at the top of every screen in this flow so they know whose log they're in.
- After logging, show a quick celebration: stars pop and the book on their shelf glows. Read the result aloud with text-to-speech, for example "Great job Maya! 15 minutes of reading!"

ADDING A BOOK
- Take a photo of the cover with the tablet camera. This is the main way to add a book, so kids can recognize their books without reading titles.
- Title and author are optional and can be typed later by a grown-up.
- The book goes on the kid's "Reading Now" shelf.

FINISHING A BOOK
- A big "I finished it!" button on each book.
- Confetti celebration, then the kid rates the book with 3 big emoji faces (loved it, it was okay, didn't like it).
- The book moves to their bookshelf.

THE BOOKSHELF (each kid's main visual)
- An illustrated wooden bookshelf that fills with colorful book spines as they finish books. Each spine uses a color pulled from the book's cover photo.
- The kid's emoji sits on top of the bookcase like a little mascot.
- Tapping a spine shows the cover, the date finished, their emoji rating, and total minutes spent on it.
- When a shelf is full, add a new shelf above it so the bookcase grows taller over time.
- Picture books and chapter books both count as one book each.

STREAKS
- Show each kid's streak as a little plant that grows a new leaf for each day in a row they read, and blooms a flower every 7 days.
- If they miss a day, the plant doesn't die. It just stops growing and waits for them. No guilt or sad visuals.

FAMILY GOAL
- A shared goal the whole family works toward together, set on the settings screen, like "1,000 minutes = pizza night."
- Shown as a big progress bar or a jar filling with colorful marbles, with everyone's minutes adding to it. Each kid's marbles are in their favorite color, with their emoji next to their share.
- A celebration screen when the goal is reached, then an easy way to set the next one.

KIDS
- Each kid has a name, an emoji avatar (like 🦊, 🦄, 🐸, or ⚽), a favorite color, and an optional daily minutes goal (for example 20 minutes).
- No photos of the kids anywhere in the app. The emoji is how each kid is shown everywhere.
- If a kid has a daily goal, show it as a ring around their emoji on the home screen that fills as they read today. A full ring gets a star.

GROWN-UP VIEW (in settings, same screens on the tablet or a phone)
- Add, edit, or remove kids. Choose each kid's emoji from a big, easy emoji picker and their color from a row of color swatches.
- Edit or delete books and reading entries, in case something was logged by mistake.
- Set daily goals and the family goal.
- A simple stats page per kid: minutes this week and this month, books finished, longest streak, and favorite-rated books. Use simple bar charts.

VISUAL STYLE
- Warm, playful, uncluttered. Soft rounded cards, cheerful but not neon colors, a large rounded font (like Nunito or Baloo).
- Cozy library feel: warm wood tones for shelves, soft paper textures, sunny yellow for stars.
- Gentle animations only: book spines sliding onto the shelf, plant leaves growing, confetti when a book is finished, the kid's emoji doing a little bounce when tapped.
- Optional dim night mode from 8pm to 6am.

TECHNICAL
- Work well as a full-screen web app on a tablet, and as a normal mobile web app on phones.
- Timers must keep running correctly even if the screen is tapped away or the app is switched.

Logins: the part not to skip

Every one of my apps has a login, and that's on purpose. It's what keeps your family's stuff safe if the link ends up somewhere it shouldn't.

• The login is your lock
  Most family apps end up Public, because Private apps need a paid plan (more in Keeping your apps running). Public means anyone who has the link can open the app. Links travel: a text to the other house, a screenshot, a browser on a borrowed tablet. If yours ever leaks, the login is the only thing standing between a stranger and your family's calendar, notes and kids' names. Without one, the link itself is the only lock.
• Your Base44 account and your app login should not be the same
  The account you build with owns everything: every app, the editor, your credits and your billing. Don't use it to sign in to the apps themselves, especially on a tablet the whole family touches. If you signed up for Base44 with your Google account, use a different email, not that same Google login, for each app's login. I sign in to my family apps with a separate, non-Google account, so the fridge never has the keys to my builder account.
• One family login for the fridge
  For apps that live on the fridge tablet, one shared family login is simplest. Kids tap their name inside the app instead of signing in. Ask in your first prompt for the tablet to stay signed in so nobody has to type a password at breakfast.
• Test it signed out
  Open the app's link in a private browser window. You should land on a login screen, not your family's data. If you can see anything personal, ask Claude for a fix prompt before you share the link with anyone.

Keeping your apps running

Building is the fun part. Here's what it takes to keep the apps working on the fridge after that. Base44 changes its plans and prices from time to time, so check Base44's pricing page before you pick one.

• Building costs credits; using mostly doesn't
  Credits get spent when you ask Base44's AI to build, change or fix something. Your family tapping around the app every day is not the same thing. Budget your credits for new features and fixes.
• The free plan
  The free plan gives you 25 message credits a month, capped at 5 a day, and up to 5 apps. Unused credits don't roll over. Your app lives at an address like yourapp.base44.app. That's enough to build one or two family apps if you're patient and put everything in the first prompt.
• Paid plans
  The Starter plan runs about $16 a month billed yearly, or about $20 month to month. It bumps you to 100 message credits a month, unlimited apps and private apps. Bigger plans (Builder, Pro and Elite) add more credits, but a family doesn't need them. Six apps puts me past the free plan's five-app limit, so I'm on Starter.
• Public or private links
  Every app has a visibility setting. Public means anyone with the link can open the app, which is exactly why every app gets a login (see Logins above): if a public link leaks, the login keeps your family's data behind a locked door. Private means only people you invite can get in, and it's only on paid plans. Either way, keep the link to yourself and stick to first names and emojis.
• If you stop paying
  Canceling doesn't delete anything. You keep your paid plan until the end of the billing period, then drop to the free plan with its limits: 5 apps, no private apps and fewer credits. If you have more than five apps or any private ones, sort that out before you cancel, and make sure every app that turns public still has its login.
• Keep a little in reserve
  Kids find bugs adults never would. Leave a few credits each month for fixes, and keep your prompts in one place (I log mine) so you can rebuild or tweak an app without starting from scratch.

Get every prompt I used, free

The free Fridge Door Family Prompt Pack gives you two routes:

• Route 1: As I built them
  55 of my 56 prompts word for word, in the order I used them, with what each one cost and whether it worked. The one I left out uses the prompts from my paid Gratitude Jar Maker. Follow along to see how a real build goes, detours and all.
• Route 2: If I started from scratch
  One prompt per app, rewritten with the login, settings, sample data and every fix already built in, plus add-ons for the Two House Hub holidays, the Sleeps Until photo reveal, Gratitude Jar's dinner mode and Family Light's Bible verses. Paste one and skip the detours.
