What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

MyTracks is an app that helps you keep track of your location using GPS data. It's perfect for various activities like hiking, running, walking, biking, and more. This app uses advanced technology to provide precise measurements and calculations. Here's what you can do with MyTracks: - Track your route: Whether you're hiking, running, or cycling, MyTracks can record your path and show it on a map. - Save favorite locations: If there are specific places you want to remember, you can mark them as favorites in the app. - Import and export data: MyTracks allows you to import and export data in various formats such as CSV, GPX, KML, and KMZ. - Improve accuracy: You can take static GPS observations to get more accurate waypoints for your tracks. - Easy navigation: The app provides a waypoint guide on the compass, making it easy for you to navigate to specific locations. - Customizable waypoints: You can add waypoints manually or import them from your favorite locations. You can even add vectors with angle and distance. - Coordinate conversion: MyTracks allows you to convert between four different coordinate formats (Decimal, DMS, MGRS, UTM) at any time. - Additional features: The app displays glide ratio during recording, offers compass options in degrees or mils, supports MGRS Grid overlay on the map, and allows you to create routes to follow before starting your track. - Detailed records: You can view your tracks on a map and replay the route. The app provides detailed statistics about your track and displays the saved waypoints associated with each track. You can also change the color of your tracks for easier identification. Please note that using GPS continuously in the background can drain your device's battery quickly. If you have any feedback or questions, please feel free to contact us at [email protected]

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
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.
