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.

Now works with CarPlay!! DS1 Companion™ is a feature rich app, designed to give you the most out of your DS1 radar detector, while enhancing your driving experience along the way. Featuring intelligent alerts and advanced muting! DS1 Companion™ is the COMPLETE solution to enjoying your DS1. **** NOTE *** Make sure to upgrade your DS1's firmware to version 1.21. Previous versions prior to 1.15 will not keep the detector muted after you mute it. The DS1 Companion™ app leverages years of optimizations and features from V1 Companion™ (Available separately on the app store for owners of the Valentine One radar locator). Building on this legacy, the DS1 companion app adds new systems to support Radenso's detector's unique abilities and features. Enhanced GPS location based 'false muting' via SpotLocks™ - All future updates to this app are free to purchasers of DS1 Companion™ DS1 Companion™'s alerting and muting systems are fully optimized for the DS1 platform. Intelligent voice announcements and on-screen visuals will always keep you informed and aware of the situation around you. NOTE: DS1 Companion™ requires a Radenso DS1 radar detector with firmware 121 to function correctly. DS1 Companion™ full feature list: • SpotLocks™ - Location based false silencing has never been this good or easy. Turn on the intelligent location-based learning and let DS1 Companion™ do the rest. Or you can manually 'lock' or 'unlock' locations with ease from the main alert screen. • Works seamlessly with the DS1's auto mute memory, manual mute memory, k-block, and K X Low Speed built in muting. • Ability to set the DS1’s internal detector settings (more coming in free future upgrades). *Req US Version 1.21 firmware.

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.
