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.

With BP Log you can easily monitor and log your blood pressure, pulse and body mass values. The App can also sync your blood pressure, pulse and body mass values with the Health app. You can manually import and export the data to the Health app or automatically sync the values on capturing them in the BP Log app or on the app startup. The App also includes a cockpit page to display the main information about the latest captured values as dynamic charts and statistics where you can see the different min and max values and the WHO classification. You can create a user profile that optionally can be exported within the cvs export to send data directly to your doctor. Let the app remind you to measure your blood pressure. Feature list: • monitor blood pressure, pulse and body mass values plus the pulspressure and mean arterial pressure values (MAP) • cockpit with dynamic diagrams providing touch support • day time related data analytics • dynamic calculation of min/max/average values • WHO classification of blood pressure data • statistics regarding the WHO classification • Health integration - sync items with Health data • create daily reminders • create and manage user profile • Export data as PDF or CSV file, optional include profile • available languages: english, german Security: BP Log uses only local storage and health kit connections. Therefore your data is not saved on any third party cloud storage nor is an separate login required! Do you have any suggestions or ideas for improvements? Don't hesitate to send us your feedback via the integrated feedback functionality inside the app settings. Hint: BP Log does not measure your blood pressure itself. You only can manually input your data or import/sync data from Health.

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.
