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
Dayloom is a calm daily planner for the life behind the calendar. Not a productivity system. Not a habit tracker. A quiet, private space to move through your day with intention. Plan your day with Daily Threads — recurring rituals that matter to you. Weave in tasks, appointments, and focus sessions. Then close the day in Reflections, a private journaling space that stays entirely on your device. No accounts. No tracking. No noise. Everything you enter lives on your phone and nowhere else. What’s inside: Daily Threads — your personal rituals, beautifully designed and waiting each morning. Weaves — tasks and appointments woven into your day without pressure. Focus Sessions — quiet, timed spaces for the work that needs your full attention. Reflections — a private space to capture what your day held. Write freely. It never leaves your device. Rhythm — a gentle record of the days you showed up for yourself. Progress — not a performance score. A quiet look at the space you made for yourself. One-time purchase. No subscription. No upsells. Yours.

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.
