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
RepLock Exercise to unlock your apps. RepLock is a screen time control app that blocks distracting apps until you complete a short exercise. Instead of relying on willpower or timers, RepLock introduces a simple rule: If you want screen time, you earn it. Before opening selected apps, complete a few push-ups. 1 push-up = 1 minute of app access. This turns passive scrolling into physical action. How RepLock works • Choose the apps you want to limit • RepLock blocks them • Do push-ups to unlock them • Earn screen time through movement No complicated systems. Just a clear rule. Key Features Exercise Unlock • Unlock apps with push-ups • Built-in pose detection using your camera • Anti-cheat movement verification App Blocking • Block distracting apps like TikTok or Instagram • Set screen time limits • Automatic enforcement before opening apps Why RepLock exists Scrolling requires almost no effort. Movement requires real effort. RepLock connects the two. The result: Less scrolling. More movement. A healthier relationship with your phone.

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.

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.
