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
My Wheelie Tracker records your route via GPS and automatically detects wheelies using your iPhone's sensors — so you can focus on riding. Built for mountain bikers, motocross riders, BMX athletes, and anyone looking to learn, practice and improve their wheelies. Live Ride Tracking See your route on a live map. Wheelie duration is visible at a glance, so you always know how your session is going. Automatic Wheelie Detection Track your bike's angle continuously — every wheelie is marked the moment it happens, including duration and position on the map. Your Data Stays on Your Device Keep your data yours — stored locally, never shared, never sold. Session Review Get a full session summary after every ride: total duration, number of wheelies, and your best wheelie of the session. See exactly where on your route each wheelie happened.

Opportunities
AI-GENERATED OPPORTUNITY HYPOTHESES
These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.
Hypothesis 1
Implement social sharing for achievements to boost motivation.
Assumption to check: Lack of user engagement features like social sharing
Validate with people who use this workflow before building.
Hypothesis 2
Add more dynamic charts and graphs for better insights.
Assumption to check: Limited data visualization options
Validate with people who use this workflow before building.
Hypothesis 3
Integrate reminders to encourage regular tracking.
Assumption to check: No reminders or notifications for activity tracking
Validate with people who use this workflow before building.
Hypothesis 4
Enhance UI with more appealing visuals and themes.
Assumption to check: Basic UI that may not appeal to users
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.

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.
