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.

App Store description
Attack Alarm is a personal safety app designed to help you react quickly when you feel unsafe. At its core is a fast one-tap alarm that can play a loud siren to attract attention nearby, but the app also gives you extra tools for situations where you need a quieter or more discreet response. Choose between Loud Mode for an immediate alarm, or Silent Mode to access safety tools without sounding a siren. You can also customise how the alert behaves with different alarm tones, screen pulse, torch flash, brightness boost, and optional spoken help phrases. Attack Alarm also helps you prepare for the next step. Choose a trusted contact from your contacts, quickly open Messages with a pre-filled SOS message, call your trusted contact, or call emergency services for your region. If location access is available, the app can include your current Apple Maps location link in the message. For extra reassurance, Attack Alarm can help you find nearby places such as police stations, hospitals and pharmacies, or open a fake call screen to help you leave an uncomfortable situation more naturally. The app also includes an on-device incident timeline, so you can save notes, keep a record of events, and export the timeline afterwards if needed. Features • One-tap personal safety alarm • Loud siren mode for immediate attention • Silent mode for discreet access to safety tools • Two alarm tones: Classic and Pulse • Optional spoken help alert • Spoken alert languages: English, Spanish, French, and German • Screen pulse effect for extra visibility • Torch flash burst • Temporary screen brightness boost • Trusted contact selection from your contacts • Quick SOS message preparation • Quick call to trusted contact • Emergency call options for your region • Nearby help finder for police, hospital, and pharmacy locations • Fake call screen for uncomfortable situations • Incident timeline with notes and export sharing • Designed for fast access and simple use Attack Alarm is designed to help you feel more prepared, more visible, and more in control when you need support quickly. Stay safe.

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.

BUILD KIT DIFFICULTY
Intermediate
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.
