Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

Just a note: some features may be available depending on your hearing aid model. Check below for details. • Adjust the sound volume for each hearing aid together or separately • Mute surroundings for better focus • Switch between programs set by your hearing care professional • Check battery levels • Use SpeechBooster to reduce background noise and enhance speech (available for all hearing aid models except Oticon Zeal™, Jet PX, Zircon, Opn™, Ruby) • Stream calls, music, and podcasts directly to your hearing aids (availability may vary depending on your phone model) • Find your hearing aids if lost (requires location services to always be turned on) • Access app support and troubleshooting solutions • Meet your hearing care professional for an online visit (by appointment) • Adjust streaming sounds with streaming equalizer (available for all hearing aid models except Oticon Opn™, Siya, and Jet) • Adjust sounds around you with sound equalizer (available for Oticon Reveal™; Verit ™, Play SI™, Zeal™, Intent™, and Real™) • Track your progress with HearingFitness™ feature (available for Oticon Reveal™, Verit™, Play SI™, Zeal™, Intent™, Real™) • Handle wireless accessories paired with your hearing aids such as TV Adapters, Oticon EduMic or ConnectClip • Connect to and adjust an Auracast™ broadcast (available for Oticon Reveal™, Verit™; Play SI™, Intent™, and Zeal™) • Get reminders to replace your wax filters to maintain sound quality (available for Oticon Reveal™, Verit™, Play SI™, Intent™, and Zeal™) • Reduce background noise while streaming with Streaming comfort (available for Oticon Reveal™) First use: You need to pair your hearing aids with this app to use it to control your hearing aids. App availability: The app is compatible with most hearing aid models. If you have hearing aids from 2016-2018 and haven't updated them yet, a hearing aid update is required for this app to work. We recommend regular hearing aid updates during your routine check-up with your hearing care professional. For optimal performance, we recommend updating your device to iOS 18 or later.To check the latest list of compatible devices, please visit: https://www.oticon.com/support/compatibility

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
