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
DriveLog turns the 40–60 hours of supervised driving your state requires into a clean, signed PDF the DMV will actually accept. No paper log lost in the glovebox. No spreadsheet nobody updates. Just a one-tap timer on the home screen, a Lock Screen Live Activity while you drive, and totals that add up to the line on the form. — FEATURES — • One-tap Start / Stop on the home tab. Survives lock screen, backgrounding, and Dynamic Island. • Per-trip metadata DMVs ask for: weather, road type (residential / city / highway / freeway / rural), supervisor, day or night. • Dashboard with three running totals — total, day, night — compared against the requirement for your state. • Recent trips list, filter by All / Day / Night / This Week, swipe to edit or delete. • Built-in defaults for all 50 states + DC. Override per profile if your state's rules differ. • Live Activity + Lock Screen widget show elapsed time without unlocking your phone. • Print-ready PDF export, US Letter, suitable for the road-test counter. — PRIVACY — Everything stays on your iPhone. DriveLog has no accounts, no analytics, no ads, no third-party SDKs, and no network calls. The only way information leaves your device is if you choose to share an exported PDF. — FOR PARENTS — DriveLog is built for the family running the supervised-driving program at home: a teen who can start a trip in one tap on the dashboard, a parent who can pull up a signed PDF on DMV day. No subscription. A one-time Pro unlock removes the 20-trip cap and turns on PDF export. Ready when you are. License in hand by next appointment.

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.

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.
