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
Anchor helps you start focus sessions, block distractions, and stay in flow without pressure. No subscriptions, ever. Set a warm-up, begin a focus block, and let Anchor use Screen Time to shield distracting apps and websites while you work. For stronger accountability, you can use any card to "lock" and "unlock" distracting apps while you work. When a thought pulls at your attention, park it in Notes and return to it later. If you are still in flow, add five more minutes. If you drift, log it and keep going. When the session ends, Anchor suggests low-dopamine breaks so you can reset without falling into scrolling. Anchor is built for momentum, not guilt: no streak pressure, no noisy rewards, just a calmer way to protect deep work. Features: • Focus timer with warm-up and cooldown • Screen Time app and website blocking • Optional NFC-based unlock flow • Shortcut NFC automation support • Quick notes for distracting thoughts • Low-dopamine break suggestions • Daily focus summary • Calendar focus map • Session texture timeline

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.
