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
Are We There? is a simple, privacy-first transit alarm for bus, train, subway, and ferry riders. Set your destination, start your trip, and put your phone away. Are We There? tracks your location in the background and alerts you with sound and vibration when you're approaching your stop — so you can read, nap, or listen to music without anxiety about missing your station. HOW IT WORKS - Search for any destination or drop a pin on the map - Set your alert threshold — get notified when you're a certain distance or percentage of the way there - The app tracks your trip in the background, even when your phone is locked - When you're close, you'll get a sound and vibration alert — on screen and via notification PRIVACY FIRST Are We There? collects zero data. Your location never leaves your device. No accounts, no tracking, no ads — ever. WORKS WHEN YOUR PHONE IS LOCKED Notifications alert you even when the screen is off, so you never have to keep the app open. TRIP STATS See your duration, distance traveled, and top speed at the end of every trip. SAVE YOUR ROUTES Save frequent destinations for one-tap trip starts.

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.

Intermediate
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.
