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
No subscription. No in app purchases. One time purchase for lifetime access. You've tried journaling before. The blank page stared back. You wrote three pages one day, then nothing for a month. Minute Journal is different, it only asks for 60 seconds. Every day, you get a thoughtful prompt. A timer starts. You write whatever comes to mind. When the minute ends, your entry is saved. That's it. It sounds simple. But those 60 seconds add up. Day after day, you start noticing patterns in your thinking. You build a streak that feels worth protecting. You create a record of your inner life that you'll actually want to look back on. Features: * 60-second timed writing sessions that remove perfectionism * Fresh prompts * Streak tracking that rewards consistency, not word count * Streak recovery so one missed day doesn't erase your progress * Full history of past entries you can revisit, edit, or reflect on * Daily reminders to keep your habit alive Minute Journal isn't about writing beautifully. It's about writing honestly. One minute at a time.

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.
