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
Create a mileage request from saved business trips, keep its agreed rate with it, and track the balance as payments arrive. HOW IT WORKS 1. Open Reimbursement Desk from Trips. Explore the payment example or select business trips, enter the payer and agreed USD rate, and choose whether to include tolls and parking. 2. Review and share the PDF and CSV yourself, then mark the request as submitted. Submitted trip and rate snapshots are fixed; original trip logs stay unchanged. 3. Record partial payments, reverse mistaken entries and see the remaining balance. Cancel an unpaid request to release its trip snapshots for reuse. Existing mileage logs, exports, references and date-based rate calculations remain available. The bundled 2026 rates now distinguish January–June from July–December; saved custom flat rates are preserved. Record-check wording describes populated fields rather than promising audit readiness. WHAT TO KNOW Manual USD requests and payment records only. The app does not send requests, process payments, verify reimbursement agreements or determine tax eligibility. Up to 100 requests with 200 trips and 200 payment entries each. Original trip records remain editable independently; saved request snapshots do not change. iPhone and iPad.

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.
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.
