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.

This application is a utility for breweries or bars to manage their mug club members. Do you currently use a spreadsheet, pen and paper, or other method to track your members? Try using this application to manage those members and you will see how much time and effort it can save. All of your member data is stored in the cloud and is accessible on any of your devices, no matter where you are (with internet connection). You can see members whose membership is expiring soon, track members birthdays, send a message or email to your members, and perform many other organizational tasks. Here's an example review from one of our users: The Mug Club app is a tool that our brewery needed. We were lucky enough to have implemented this app when we were only a few hundred members in and only a couple of dozen mugs to keep track of. We now use this app to track the close to 2000 total members we have had and about 700 mugs with their location! We can see easily, who is a lifetime member, who is a current annual member and who has expired. We can get pictures of our members and take notes on them to help us get to know our customers better. Exporting our member list is simple. Entering a new member is also very easy. This app is so user friendly. It is a must-have for any brewery that plans to have a mug club. Requires iOS 9.0 or later

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.
