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.

Find every location with your iPhone GPS Based Compass Navigation Get the best out of your iPhones Compass and GPS! Helps you to find a target location by following a smart arrow on the iPhone display. The arrow shows the air-line to the target. The display also shows your speed, your altitude and the distance to the target location. It also has a built-in compass! Why you should use it: - find your target location on a walking-tour - find your car (parking place) - use this app for your Mountainbike or Hiking Trip (Altitude and Speed Display are built-in) - find back to your hotel in holiday - get the air-line distance to every location in the world - find your way home even if you had one over the eight :) - use this app to save the GPS coordinates of locations you like (unlimited!) - use it as navigation tool if you are on a boat or on a fishing trip - built in compass - measure the distance between your location and every place on earth Features: - rotating map - displays your speed (using the GPS, displayed if available) - displays your altitude (using GPS) - store an unlimited amount of target locations - save the actual position as target location - select a target location on the map - prevent display from lock (configurable) - choose the unit of length (kilometers/meters or miles/feet) - shows the actual distance to your target location Way Home Finder is perfect for offroad use, where apps like Navigon or Tom fail cause of the missing map material. I was surprised that many ship - yacht - boat owners like this app! Thanks for your feedback!

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.
