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
FusionCam is a minimalist iOS, iPadOS, and macOS app for viewing Dashcam and Sentry Mode footage from Tesla vehicles. It scans your dashcam folders, groups clips into events automatically, and plays the selected camera feeds together in a synchronized grid with real-time telemetry overlays like speed, gear, and Self-Driving status. A clean, date-grouped library lets you jump straight to any event and filter by Recent, Saved, or Sentry. Trim a clip down to the moment that matters, then export the full multi-camera grid with the telemetry overlay built right in. Multi-camera playback, trimming, the telemetry overlay, and landscape export up to 1080p are included for free, and always will be. A one-time FusionCam Pro unlock adds: - Watermark-free exports - Vertical video for YouTube Shorts and Reels - A social media handle overlay to brand your clips - High-quality exports up to 4K

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.

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.
