Generating… usually about a minute.
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.

FlightPack is a complete easy-to-use solution designed for hot air balloon pilots. FlightPack is a flight tracking app with offline maps, overlays, load calculator, weather forecast, logbook and other unique features. The track color changes at different altitudes showing the winds layers and your crew will see your track in real-time in a webpage! Main Features: • GPS track with different colors depending on the altitude. This helps identify the winds layers. • Your crew will see your track in real-time in the webpage www.flightpacktracker.com • See other pilots tracks in real-time while you fly. Their tracks colors will indicate their winds. • Free maps worldwide (OSM) for offline use during flight. Google Maps is also available. • Optimized for low power. You can turn off your screen while your flight is being recorded (the last screen shown needs to be the app). • Auto landing detection if you forget to stop the track. • Start recording before you start flying. Track can be automatically trimmed to obtain reliable flight duration data. • KML overlays can be used to map out electric lines, Prohibited Zones (PZs), targets... You can create them with Google Earth. • Vertical velocity and precise altitude for devices with barometer. • Weather map with forecast and wind status at different altitudes. • Share your track easily in Facebook, Twitter... • Load calculator with user defined balloons. • All integrated in a flight logbook with search capabilities. Database can be exported in Excel compatible format. All your data can be transferred and backed up. *Requires iOS 14 or higher and GPS capable devices. *Continued use of GPS running in the background can dramatically decrease battery life. Please report any issues and suggestions to [email protected]. Have a good flight!

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.
