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.

Why Libre app: • Readings automatically update every minute on your device[α] • Insights a tap away – helps you see your trends and patterns to better understand your diabetes • Real-time alerts[λ] gradually increase in volume – you can choose to silence[θ] them for a period of time • Share[*] readings with your doctor or loved ones through LibreView[±] and LibreLinkUp[**] COMPATIBILITY Compatibility may vary between operating systems. Please check our website for more information about device compatibility. Consult a healthcare provider (HCP) to determine if this product is right for you or if you have questions about using it for treatment decisions. α. The FreeStyle Libre systems apps are only compatible with certain devices and operating systems, and may require registration with LibreView. Check our website for device compatibility before use. β. The Libre app is compatible with all FreeStyle Libre systems sensors except the preceding FreeStyle Libre 14-day sensors. δ. The Libre app for smartwatches is only compatible with certain devices and operating systems. Please check our website for more information about device compatibility before using the app. Use of the Libre app may require registration with LibreView. The Libre app for smartwatches should not be used to make treatment decisions. Please follow the Libre app instructions on your smartphone. ε. Glucose data and alerts appear on your smartwatch only when your phone is within sensor range. Alerts are mirrored from the Libre app, and your phone must have notifications enabled. θ. Silent mode lets users silence signal loss and alarms for a period of time as indicated in the user manual. During this time, alarms will not sound even with Override Do Not Disturb enabled, though visual and vibration alerts may still appear based on phone settings. λ. Notifications will only be received when alarms settings are enabled, turned on and sensor is within a certain range unobstructed of the reading device. Refer to user manual. *. The user’s device must have internet connectivity for glucose data to automatically upload to LibreView and transfer to connected LibreLinkUp app users. ±. LibreView is intended for assisting people with diabetes and HCPs to review and analyze historical glucose data to support diabetes management. It is not intended for treatment decisions or as a substitute for professional medical advice. **.

Assumption to check: Users find it difficult to navigate through the app due to too many features.
Validate with people who use this workflow before building.
Hypothesis 2
Offer clearer information on premium features and a trial period.
Assumption to check: In-app purchases can be confusing and not clearly defined.
Validate with people who use this workflow before building.
Hypothesis 3
Implement thorough testing and user feedback mechanisms to enhance stability.

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.
