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.

▸ Automatic GPS based Flight Time Logger for Pilots ▸ Records Block Time, True Flight Time and Landings ▸ Shows Elapsed Times and Ground Speed during Flight Flight Time helps you focus on flying instead of noting down take-off and landing times while you are in the cockpit. The Flight Time iOS app is using GPS to automatically log them for you. All you have to do is enter your plane's stall speed so that the app knows whether you are flying a Citabria or an F-16 and turn GPS on before your flight. Over at the airport restaurant, tap on parked and see all the information you need to fill out your logbook. Yes, the restaurant is optional, but you need to press parked before you drive away from the airport, so the app can figure out your correct blocks-on/end time. Features: - Universal App for both iPad and iPhone - Email flight times directly from the app to your student or instructor - Detects block-off, take-off, landing and block-on times automatically with GPS - Allows for manual input of flight phases making this app usable even with GPS disabled - Flight Time keeps logging in the background allowing you to use other apps simultaneously or put your phone to sleep - Continuously displays totals so far in current flight - Keeps screen on while app is in foreground - Displays current ground speed - Choose Local time or UTC - Round to minutes, or display with seconds - Record every landing or full-stops only Disclaimer: - Because 'Flight Time' uses the GPS/ground speed to decide whether you are flying or are on the ground, very slow flight during stall training could be detected as landings and very fast touch and goes could be missed. The flight time will still be correct, just double check the number of landings if you do touch and goes, stall training or aerobatic flight when not in full-stop only mode. - Hobbs (engine running time) is usually slightly higher than block time (time from first to last movement of plane). - Continued use of GPS, even when running the app in the background, can decrease battery life significantly (to about half a day, particularly on older phones).

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.
