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
Track every bar and lounge on your cruise. CruiseNCrawl covers Royal Caribbean and Carnival Cruise Line ships: pick your ship, check off each venue as you visit, and make it one for the story. Note the bartender's name and the drink you had at each stop, and have the list emailed to you when your crawl is done, a handy place to look up those favorite bartenders' names for the after-cruise surveys. NEW: Scavenger Hunts. Generate a custom hunt for your next sailing, solo, with your crew, or as a bar crawl twist. Generating and previewing hunts is free; saving them requires Master Crawler. Become a Master Crawler and unlock: • Crawl histories saved • Unlimited custom pub crawls with event names, dates, times, and meet-ups • Save and copy your Scavenger Hunts • Invite friends and join group crawls • Email completed lists, including bartender names • Exclusive Master Crawler badge • And more to come!

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.

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.
