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
You're cooking, presenting, parking, wrapping up a meeting. You set a timer and walk away. Then it goes off — and you're scrambling. 1 Minute More fixes that. Set as many warnings as you need, at any point in your countdown. Sound at 10 minutes. Another at 5. A final one at 1. You're always a step ahead, never caught off guard. THE ONLY TIMER THAT WARNS YOU BEFORE ZERO. Every other timer app — including the iOS Clock, Apple Watch, and the most popular alternatives — alerts you at one moment: when it's already too late. 1 Minute More gives you unlimited custom warning points, so you can prepare, wrap up, and transition on your terms. Set it. Put your phone down. We'll handle the rest. Unlimited custom warnings at any point in your countdown Beautiful metallic 3D numbers with particle effects Custom synth sounds for each warning Saved presets for your most-used timers Live Activity on your lock screen and Dynamic Island No ads. No subscription. One-time purchase. One timer. One purpose. Always ahead.

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.

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.
