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
Your travels deserve more than a list. Scratch Atlas turns the places you have lived, visited, and dream of exploring into a personal world map that grows with you. Start by scratching the countries that already mean something to you. Then keep building your Atlas as life takes you somewhere new. Keep track of the places you have visited, the ones you have called home, and the ones still waiting for you. See your progress across the world, revisit your memories, and discover the story your map tells. Add dates, notes, and photos to make every place feel personal. Your Atlas becomes a living record of the journeys, people, and moments that shaped you. When you want to share it, create beautiful photos and videos directly from your map. Whether you have explored half the world or are just planning your first trip, Scratch Atlas gives every place a place in your story. Scratch it. Remember it. Share it.

Validate with people who use this workflow before building.
Hypothesis 2
Improve performance and add features like trip sharing or social media integration.
Assumption to check: Poor user ratings suggest a lack of features or poor performance.
Validate with people who use this workflow before building.
Hypothesis 3
Introduce premium features or a subscription model for advanced functionalities.
Assumption to check: No in-app purchases or upgrades available, limiting monetization.
Validate with people who use this workflow before building.
Hypothesis 4
Redesign UI for a cleaner, more modern aesthetic, focusing on user experience.
Assumption to check: User interface may feel outdated or cluttered.
Validate with people who use this workflow before building.
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.
