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
Be prepared and plan smartly with global minute-by-minute and street-by-street hyper accurate forecasts, rain and snow alerts, air quality maps and wind speeds. Tomorrow's unique forecasts are in use by industries, from aviation to on-demand players, who can’t afford to make a bad call based on weather. You shouldn’t have to either. What people are saying ? The Washington Post - “Alerting you when it’s about to rain, down to the minute, all around the world.” Mashable - “Bad weather is one thing technology won't let us escape, no matter how hard we try. The new ClimaCell app will at least help you be prepared.” Fortune Magazine - "The new app gives forecasts for precise areas, as small as a city block" Tomorrow's MicroWeather - based on data from the connected world, traditional data sources, and new, cutting-edge modeling - is hyper accurate, specific and relevant to your life. • By-the-minute, by-the-street forecasts up to three hours ahead • High resolution: weather analysis at 500 meters resolution • Refresh: updated forecast every minute • Stay safe with severe weather alerts and safety tips from the National Weather Service. What our users are saying? "Best weather app! I absolutely love this weather app! It alerts me when it’s going to rain, has an easy to view radar map on the home screen and is extremely easy to navigate through. I would choose this app over Accuweather, which I have used for years!" - Bchan80. "Super accurate weather app This is the coolest weather app. The data is the lost accurate and precise by far. Better weather prediction and user interface than Dark Sky. If you really want to get accurate weather, check out Climacell." - Markymark7419 "Accurate and easy! Love this app! It’s a game changer. So much more accurate down to the minute, for example I’m an avid biker and motorcycle rider, knowing when and where the rain will come with this level of precision is awesome." - RBrider65 Hello #OutsmartWeather ----- Privacy & Feedback • Our Privacy Policy can be viewed here: https://www.tomorrow.io/consumer-app-privacy-policy • Our EULA can be viewed here: https://www.tomorrow.io/consumer-app-agreement • If you have any questions or suggestions about our service, please do not hesitate to get in touch at [email protected]

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.
