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
Scanrad.io brings public-safety, marine, railroad, and other radio to your iPhone from the scanrad.io network — both live and recorded. Tune into a growing network of radio channels, listen to what's happening right now, or jump back to any earlier moment and hear exactly what came across the air. FEATURES • Live & recorded audio — play the live edge of a channel, or scrub back to any recent transmission and listen from there. • Browse by decoded paging tones — channels with paging tones index DTMF, QuickCall, MDC and FleetSync received to instantly jump to when a specific unit was dispatched • Browse by activity — every channel shows its recent transmissions grouped by time, plus an hourly activity heatmap so you can find the busy moments at a glance. • Favorites — star the channels you follow most for quick access. • Background playback — keep listening with the screen locked, and control playback from the lock screen and Control Center. ABOUT THE AUDIO Scanrad.io plays lawful, over-the-air reception of public radio transmissions. Because it's real, live radio, audio is unfiltered and a channel is only active when something is actually being transmitted — quiet channels simply mean no one is talking at that moment. Listening to these public transmissions is legal in the United States. Availability and legality of radio reception varies by region; please use the app in accordance with your local laws.

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.
