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
AlcoGrip is the no-nonsense alcohol tracker for iOS. Using AlcoGrip, you can keep track of your alcohol consumption via your phone, directly via your Apple Watch, or straight from your home screen or lock screen. Add your own drink presets or add consumptions manually, and gain insights in your alcohol usage. AlcoGrip automatically groups your consumptions in sessions, and you can see the consumptions you logged in the past 24 hours, week, month, or since the start of the year. AlcoGrip will also remind you to keep logging your consumptions, since thinking about an app is the last thing you want to do when you're enjoying some beverages. AlcoGrip can also integrate with Apple Health and Shortcuts, and provide data about your consumptions. AlcoGrip does not require any subscription or in-app purchases to work, once you got the app - it's yours forever. AlcoGrip includes: - iPhone widget for your home screen, lock screen, and smart stack - track your session, last 7 or 30 days, or year-to-date at a glance - Apple Watch complication in circular, rectangular, and corner styles - Edit any logged consumption to fix its time, drink, or notes - Swipe a logged drink in your history to log it again with the current time - Favourite your most-used drinks and search by name to keep your collection manageable - Smarter reminders that mention which drink you logged and let you log again in one tap - Integration with Apple Health - Integration with Shortcuts - iCloud sync to store your data on all your devices - Automatic grouping of consumptions in sessions - Manual consumption entry - Consumption entry based on manageable drink presets, based on a single alcoholic component or multiple alcoholic components - Insights into your alcohol consumptions - Set limits on your consumption (consumptions, standard units or grams of alcohol) per day, 7, or 30 days - See your consumption in standard drinks (definitions for multiple countries are available, as well as a custom option) - Companion app for Apple Watch to log consumptions from your wrist - Automatic reminders to help you keep logging your consumptions - Export functionality

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.

BUILD KIT DIFFICULTY
Intermediate
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.
