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
WHAT YOU GET 10–20 price errors daily Real mistakes from real retailers. AirPods for $24. A free Matcha. Concert floor seats for dorm prices. These aren't negotiated discounts — they're accidents. Instant alerts The second a price breaks, you get a notification. Not a digest. Not a weekly email. A real-time push — because these deals are gone in minutes, not days. Browse by category Tech, food, fashion, travel, gaming, beauty, events, and more. Filter to what you actually care about and ignore the rest. Community drops See what other users are finding and sharing. The best deals come from people who are paying attention. HOW IT WORKS Our team monitors pricing across the web around the clock. When something breaks — a retailer misposts a price, a promo code stacks wrong, a free item slips through — we post it immediately. You get notified. You claim it. Done. We built this for students and deal hunters who are tired of paying full price. Download is free. Turn on notifications. The next one drops soon.

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.
