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.

Track Notes is a note‑taking app that integrates with Apple Music, allowing you to record and save your own impressions and insights on songs. You can easily create notes for the song currently playing or any song in your library. Use it to analyze reference tracks in your playlists, or capture musical inspirations and observations—enhancing your personal music experience. Notes are tied to specific playback positions in the track. This lets you leave a note on a part that caught your attention and later jump right back to that point. Have you ever experienced this? - You added a song to a playlist but forgot why you chose it - You regretted not jotting down your thoughts or impressions when you first listened Track Notes solves these problems. Recommended for: - Music producers, DJs, musicians, composers, video creators—anyone who wants to document track analysis or ideas - Anyone wanting to organize key points for reference tracks in playlists - Learners studying music who want to note insights per song - Anyone who wants to preserve impressions and emotions from listening Key Features: - Create notes tied to playback positions, and play from that point - Save multiple notes per song - Search and sort your notes - Toggle between light and dark themes Please Note: - A subscription to Apple Music is required to use all features of Track Notes - Notes can only be viewed within the Track Notes app; they won’t appear in Apple Music or other apps

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.
