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
[TRY BEFORE YOU BUY!] Welcome to Easy Delivery Co. - is relaxing driving adventure with… absolutely no secrets whatsoever. Steam: Overwhelmingly Positive, 96%. You’ve just been hired as the newest delivery driver in a once-lively mountain town now buried under strange weather and even stranger residents. Cruise through scenic roads, meet the locals, and uncover the story behind the town (which is definitely 100% normal). Earn money, buy wildly overpriced fuel, upgrade your trusty kei truck, and take on delivery jobs at your own pace. Whether you’re here to chill or to dig into the town’s hidden mysteries, every road leads somewhere unexpected. Features: - Deliver packages, earn cash, and chat with the “completely ordinary” locals - Explore atmospheric mountain roads — relax or speed through (road safety questionable) - Upgrade your kei truck and unlock new routes - Simple controls, retro visuals, and a cozy mood - No strange secrets or hidden lore. None. Really. We promise.

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.
