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
Welcome to the Math 4 Nurses app! This app is geared toward future health care professionals (ie nursing students) or those who are looking for a refresher on the common math problems they will typically encounter on the job. The app is divided into numerous categories, each with its own button on the main screen. The Conversions view allows you to view all the standard Household Measures and Metric System conversions for length, weight, and volume. The Decimals view discusses decimal places and rounding. The Dimensional Analysis (DA) view describes DA and gives examples of solving problems with it. The Questions view has hundreds of real life math problems in all the various categories. It will keep track of your correct and incorrect answers, as well as provide a helpful hint if you need it. Practicing these problems will get you ready for that next math quiz or real life dosage calculation. The Ratios view describes ratios and gives example problems. The References view provides links to commonly used web sites where you can explore more about DA, watch videos, review more details about specific math fundamentals, or find considerably more practice problems. Finally the Rules view allows you to view the standard rounding rules, as well as the Do Not Use list. This app will be a helpful tool in your nursing tool kit! All the math related nursing info you need in one convenient app. Best of all, there are no annoying ads. Try it out now!

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.
