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
Make everyday wellness easier to follow. Easina brings camera-based heart rate estimates, a BMI calculator, and a blood sugar log together in one place. Check Your Heart Rate Use your phone’s camera to estimate your heart rate. Follow the on-screen guidance, view your result, and explore your heart rate trends over time. Calculate Your BMI Enter your height and weight to calculate your body mass index (BMI). BMI is calculated from the information you provide, not measured by the camera. Keep a Blood Sugar Log Manually enter blood sugar readings obtained from an external source, such as a glucose meter. Keep your readings together for easy reference. Easina does not measure blood sugar using your phone’s camera or sensors. Review Your Records Return to your heart rate results, BMI entries, and blood sugar records to review the information you have saved. Important Information Easina is intended for general wellness and personal record-keeping. It does not provide medical advice, diagnosis, or treatment, and is not a substitute for professional medical care or a medical measuring device. Always seek the advice of a doctor or other qualified healthcare professional in addition to using this app and before making medical decisions.

Add trend analysis over time with visual graphs.
Assumption to check: Limited historical data analysis.
Validate with people who use this workflow before building.
Hypothesis 3
Allow users to create accounts for saving their health data.

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.

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.
