Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.

States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.

Differentiate and validate

Hypothesis: Contractors need faster repeat invoices more than more templates.

First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.

The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.

Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

App Store description

A cozy virtual pet that lives on your Apple Watch. Your new digital companion hatches from a mysterious egg, grows through unique life stages, and responds directly to your steps and real-life movement. Walk more to help your tamagotchi-style pet thrive, or sit still and watch them get sleepy. Just wear your watch to track steps effortlessly. One purchase. No ads. No subscriptions. No in-app purchases. Family Sharing covers every Apple Watch in your family. THREE KINGDOMS, MANY SPECIES Eggs can hatch into pets from Animals, Plants, or Machines — three kingdoms, each with several species to discover. Your first pet might be a rabbit that twitches its ears when idle. Another egg could reveal something leafy, tiny, shiny, mechanical, or entirely unexpected. Every species grows with its own stage names and unique look at each stage. Collect multiple colour variants, give your pet a name, then graduate it into your family collection and start again. Build a family across all three kingdoms without seeing every surprise up front. YOUR PET FEELS YOUR DAY Eight moods shift in real time based on how active you are: Happy when you are moving. Sad when you have been still too long. Ecstatic when you blow past your typical activity. A warm morning glow greets you when you wake — brighter if yesterday was a great day. Push hard during a run or climb stairs fast, and your pet gets a temporary burst of energy. At bedtime, it sleeps. During focus time, it waits quietly without sending notifications. Your pet is not a judge. It is a mirror — reflecting your day back to you with warmth. WORKOUT STICKERS Run, walk briskly, kayak, hike, swim or climb stairs — every detected workout becomes a collectible sticker on your mood ring. Medal tiers from bronze to legendary track each workout type. Build a gallery of pet workout memories over time. BRAIN BOOST MINI-GAMES Five mini-games live right on your watch. Challenges appear throughout the day — short, sharp rounds built for quick play. Win to unlock a Brain Burst: a special mode where your pet becomes a glowing star student and earns a bonus to its activity score. SEE YOUR DAY AT A GLANCE A 24-hour mood ring circles your pet, showing how its mood shifted through every hour. Workouts arc onto the ring as coloured segments. Tap to open a timeline. WAKE UP WITH YOUR PET A morning summary greets you with yesterday's highlights — your pet's final mood and how the day ahead could shape up. GRADUATE, COLLECT, ACHIEVE When a pet reaches adulthood, graduate it to your family collection and start fresh with a new egg. Over time, build a family across all three kingdoms. Visit them in their lush habitats. Earn achievements along the way: milestones for your first egg, first hatch, first ecstatic day. Streak tiers from bronze to legendary for consecutive active days. Collection badges for raising every colour of a species or completing an entire kingdom. Graduated pets live in animated kingdom habitats on iPhone and Watch — forest, meadow, or city skyline. SEE YOUR JOURNEY Tap your pet on iPhone to explore its full story: a 30-day activity chart, a mood river that flows through your days, and a mood calendar showing how your pet felt each day. YOUR WATCH FACE, YOUR PET Nine complication styles keep your pet visible without opening the app: current mood, activity percentage, stage name, active days, pet name, or a progress arc. Mix and match to build the watch face you want. Works standalone on Apple Watch — no iPhone needed. Syncs across your devices via iCloud, so you can pick up on any Apple Watch in your family without losing a streak. PRIVACY YOU CAN TRUST Health data stays on device. No server. No account. No third-party services. Steps and heart rate are read from Apple Health only for mood and growth — never shared, never uploaded. Your watch can mirror bedtime/wake preference through iCloud so it survives reinstall; Delete All Data clears it. COPPA-conscious.

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
