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
Tally helps small resellers record purchases, sales, expenses, and profit. DEALS Record an item, quantity, purchase cost, selling price, expenses, and dates. Add a photo, category, notes, and buyer details. Track unsold, paid, payment-pending, returned, and cancelled deals. REPORTS Review monthly sales, matched costs, expenses, and profit. See inventory costs and unpaid balances across all dates. Customer summaries group related purchases and outstanding amounts. CURRENCIES Work with QAR, USD, and EGP. Enter your own exchange rates. Each deal keeps its saved rates, so changing settings does not change historical reports. LOCAL STORAGE Records stay on your device. The app works offline from first launch and has no account, advertising, bank connection, or automatic cloud sync. BACKUP AND EXPORT Export a JSON backup through the iPhone share sheet, restore a backup by merging or replacing saved records, and export CSV files for spreadsheets. Backups include saved deals, photos, settings, and rates. Unsaved drafts remain on the current device. Exported files are unencrypted. ENGLISH AND ARABIC Switch languages in Settings and choose light, dark, or system appearance. No subscription or in-app purchases. Keep regular backups: removing app data or losing your device can remove local records.

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.

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.
