What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

MyVibe is the mood-based way to play Apple Music. Tap how you feel; hear the right vibe. Ten moods to choose from: happy, hyped, focused, motivated, relaxed, romantic, worshipful, anxious, sad, and sleepy; each tied to hand-picked Apple Music playlists. VibeSense lets you type or speak how you're feeling, and an on-device AI picks the mood for you. It runs entirely on your iPhone (requires Apple Intelligence on iOS 26 or later). Calm Mode is a guided breathing session with soft music underneath. Choose 2, 5, 7, or 10 minutes. With your permission, completed sessions are saved to Apple Health as Mindful Minutes. MyVibe never reads your health data. Parental controls let you lock the explicit-content toggle behind a 4-digit PIN, with Face ID / Touch ID unlock and a one-time recovery code. Family-friendly by default. Today's Vibe widget pins your day's top mood to the Home Screen. Smarter suggestions surface a curated pick for right now (time of day plus saved places) from the wand in the header. Audio resumes automatically after phone calls and Siri. No more tapping play again. ALSO IN MYVIBE A Hide Explicit Songs toggle keeps playback clean. Heavy moods like Hype blend a clean-content playlist so the filter actually works. Custom playlists per mood let you paste any Apple Music link to override the default. Daily vibe insights show which moods you reach for and when. REQUIRES APPLE MUSIC MyVibe plays catalog content through Apple Music via MusicKit. An active Apple Music subscription is required. Some features (VibeSense) require an Apple Intelligence-capable device on iOS 26 or later. PRIVACY MyVibe doesn't track you, doesn't show ads, and doesn't sell or share your data. Mood history stays on your device. Apple Health writes are opt-in and write-only. Location is used only to surface place-based mood suggestions you've saved.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
