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
Easily bridge the gap between Google Maps and your favorite GPS navigation devices! If you own a Beeline Moto, Beeline Velo, Garmin, Wahoo, or any other GPS computer, you know the frustration: a friend sends you a great Google Maps link or location code, but your navigator cannot read it. MapsToGPX solves this instantly. With our native iOS Share Extension, you don't even need to open the app. Simply share any Google Maps route, location pin, or Google Plus Code directly from the Google Maps app to MapsToGPX, convert it to a high-quality GPX file, and open it directly in your navigation app or export it instantly. HOW IT WORKS: 1. In Google Maps, set up your route, tap on a point, or find a Plus Code. 2. Tap "Share" and select the MapsToGPX extension. 3. MapsToGPX automatically converts the coordinates and redirects you to your navigation app or exports the GPX file. It is that simple! No more manual file downloads, using clunky mobile websites, or struggle with shortened "maps.app.goo.gl" links. KEY FEATURES: • Seamless iOS Share Extension integration with expandable height for multi-stop routes. • Instant 1-tap conversion from Google Maps links to GPX format. • Waypoint Management: Easily inspect and delete intermediate points directly within the Share Extension. • Flexible Location Handling: Clear permissions guidance with the ability to export a single-point GPX without sharing current location. • Google Plus Code Support: Convert Open Location Codes (Plus Codes) into precise GPX waypoints — ideal for remote trails, campsites, and off-road meeting spots without a street address. • Intermediate Waypoints Support: See intermediate via-points on the map to feed exact road choices into your GPS navigator. • Modern, Refreshed Design: Clean, intuitive UI crafted for fast and distraction-free operation. • Built-in Onboarding Guide: Quick and clear walkthrough for effortless setup and everyday use. • Automatic resolution of shortened Google Maps URLs. • Direct handoff to supported navigation apps (via deep linking). • Multi-language support. Whether you are planning a weekend motorcycle road trip with friends or an off-grid gravel bike trail, MapsToGPX keeps you focused on the ride, not on file management. Compatible with Strava, Garmin Connect (Edge, Forerunner, Fenix), Wahoo ELMNT, Beeline Moto, Beeline Velo, OsmAnd, Organic Maps, and other GPX-supported platforms.

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.
