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 evidence
Original App Store material. Ratings and screenshots describe the existing app, not proof of demand for your version.
App Store description
Zoomable is a browser that provides a full desktop web experience. It simulates a large and resizable screen and shows the desktop version of websites, so you can stay away from those bad mobile web experiences. • Zoom freely between 1x and 3x. • Seamless transitions between portrait and landscape mode. • Supports full screen mode. • Save and manage favorites. • Lightning fast and super small install size. • Supports UI customization for both portrait and landscape mode. • Respects user privacy; the app only collects anonymous diagnostic data unrelated to browsing, and you can opt out. • [Pro] Multiple tabs. • [Pro] Customize themes. The app is designed for everyone, it works great with many websites. However, it is particularly useful for developers. For example, accessing App Store Connect and Firebase Console works great in this app because of the screen scale feature.

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.

BUILD KIT DIFFICULTY
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.
