Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
Some Noise lets you build the background sound you want instead of choosing from a fixed list. Set up to three frequency bands, add rain or thunder, and save the result to your own library. BUILD YOUR SOUND • Up to three bands, each with its own frequency, level, texture (Deep, Warm or Airy) and resonance. • A live spectrum with a handle for each band. Drag a handle to change its frequency and level. • Rain with controls for intensity, drops, distance and frequency. • Thunder that rolls in at the interval you choose. • Overall volume, plus Motion & Space: low cut, drift, breathe and width. MADE LIVE ON YOUR PHONE Sounds are generated as they play. There are no recordings, no loops and no downloads, so everything works offline. YOUR LIBRARY • Save, rename, duplicate and delete your sounds. • Choose a starting sound that plays when you open the app. • Export your library to a file and import it on another device. SLEEP TIMER • Pick a length from 15 minutes to 8 hours. The sound fades out at the end. KEEPS PLAYING WITH THE SCREEN OFF • Playback continues when you lock your phone, with play and pause on the Lock Screen. NO STRINGS No ads, no account, no subscription, no in-app purchases, no tracking. Everything stays on your device. PLEASE NOTE Some Noise is a sound tool. It is not a medical device and does not claim to treat any condition. Questions or bugs: [email protected]

Opportunities
AI-GENERATED OPPORTUNITY HYPOTHESES
These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.
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.
