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
NEW: ALERTS START ON THEIR OWN No need to open the app before you drive. Turn on Auto-Start Near Cameras in Settings > Driving Mode and set Location to Always. When you get near a speed camera, alerts start by themselves, even if the app is closed. Premium. California's new speed cameras are going live: 241 of them in Los Angeles, San Francisco, Oakland, Long Beach, San Jose, Glendale and Malibu. Speed Alert LA tells you out loud when one is coming up and what the limit is, so you can ease off before you pass it. No looking at your phone. USE THE MAPS APP YOU ALREADY USE Tap Start Drive, then switch to Apple Maps, Google Maps or Waze. Alerts keep coming with your phone locked, through your phone or your car speakers over Bluetooth or CarPlay. ONLY THE CAMERAS AHEAD OF YOU Speed Alert LA knows which way you're driving, so it stays quiet about cameras behind you or on cross streets. One alert per camera, no nagging. A HEADS-UP IF YOU'RE OVER Going faster than the posted limit as you approach a camera? You'll hear "Slow down." VOICES THAT SOUND HUMAN Pick from natural-sounding voices and choose when you hear the alert: 2,000, 1,300 or 800 feet out. EVERY CAMERA, SEVEN CITIES All 241 camera locations from official city sources (LADOT, SFMTA, OakDOT and others), with the street, the speed limit and a street-level view, on a map or in a searchable list. LA'S RULES, IN PLAIN ENGLISH Fines, warning periods, school zones, help for low-income drivers and how to contest a ticket, from official City of LA and California sources. PRIVATE BY DESIGN No account, no sign-up. Everything runs on your phone, and your location and trips never leave it. FREE: camera map, camera list, guide and a demo drive. PREMIUM: voice alerts on every drive. $4.99/month with your first month free, or $49.99/year. Payment is charged to your Apple Account. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings. Speed Alert LA is a reminder, not permission to speed. Always follow posted speed limits and traffic laws. Camera locations and start dates can change. Speed Alert LA is not affiliated with LADOT, the City of Los Angeles or any other city or agency.

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.
