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.

Belly Breath Buddy is a gentle breathing app for children who need a simple way to slow down, settle, and practise calm breathing. The app uses a friendly visual breathing guide to help children follow a steady rhythm: breathe in, breathe out, and pause. It is designed to be simple, calm, and easy to use — especially for children who may feel overwhelmed, anxious, frustrated, or dysregulated. Belly Breath Buddy can be used at home, at school, before bed, after a difficult moment, or whenever your child needs a short calming pause. Features include: • A clear visual breathing guide • Simple breathe in and breathe out prompts • Optional voice and sound cues • Gentle celebration at the end of a session • Adjustable breathing rhythm • Choice of session length • Haptics and sound controls • Language settings • Works on iPhone and iPad Belly Breath Buddy keeps things intentionally simple. There are no complicated menus, no busy rewards, and no pressure to “get it right”. Just a small, friendly breathing space your child can return to when they need it. It is not a medical tool or therapy replacement, but it can be a helpful calming support for families, carers, teachers, and children learning simple self-regulation skills. A small breathing buddy for big feelings.

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.
