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.

Solar Watch lets you monitor your SolarEdge power production right on the watch face of your Apple Watch, on the Home Screen Widget and the Lock Screen Widget on your iOS devices, and using Siri. You can create Siri shortcuts and then say for example: "Hey Siri, what's the current power" - and hear the response. To access Siri Shortcuts, tap the app menu in the top/right, then tap on "Siri Shortcuts". Every watch complication type is supported, with special attention given to complications that use gauges. During daytime, the complications are displaying current power production, and total daily energy produced. Gauges are color-coded, and show the percentage of current power vs. the maximum. During night time, the complication gauges act as a timer that counts down how much time roughly there is until sunrise. Watch app has a scrollable view with various stats, including daily, monthly and yearly total power, as well as environmental benefits and calculated revenue. Current power, daily and monthly production is also displayed in the iOS widgets, both on the Home Screen and on the Lock Screen.. Based on the robust and proven codebase that powers Thermo Watch and Watch Cam apps, enjoyed by tens of thousands of users. The app is extremely quick and efficient, with near-instant launch time, and seamless background updates. While the app's minimalist looks betray the simplicity of its operation, what they don't show is the amount of planning, design, development and refinement that went into it, ensuring it becomes something that is enjoyable to use and experience. The goal was to make a product that would not look out of place next to one of the apps bundled with the Apple Watch. Please Note: SolarEdge admin console access is needed to generate the API key that is used to sign into the app. Solar Watch does not collect any of your data. Your API Key and any app activity - all of it flows exclusively between your devices and SolarEdge. Author of Solar Watch does not access any of it, at any point. Solar Watch is not affiliated with SolarEdge, but it is created with their approval.

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.
