What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Discover, explore, and track over 16,000 abandoned ghost towns across the United States, Canada, and beyond — all without an internet connection. No subscription. No in-app purchases. No account. No ads. You pay once (or download free) and get everything. EXPLORE THE MAP An intelligent cluster map puts 16,000+ ghost towns at your fingertips. Zoom in from a world view to individual pins, tap any pin for a quick summary, and open the full detail view for photos, history, satellite imagery, and more. Filter by any of the 10 town types — Mining,Railroad, Logging, Oil, Agricultural, Military,Fishing, Resort,Company Town, and Unknown. Filter by US state or Canadian province using the Region picker. The map automatically zooms to fit your selection. Tap the dice button to jump to a random ghost town. Search for any city to explore what's nearby. LIVE COMPASS Open any ghost town and tap the compass card to get a full-screen live compass. The rose rotates as you turn your device — point the dot to the top arrow and you're facing the ghost town. Near Me mode shows your 3 closest towns simultaneously, each in a distinct color. NEAR ME Find ghost towns within 25, 50, 100, or 200 miles (or km) of your current location, sorted closest first. Tap the compass button on the map to see bearing directions to your nearest towns in real time. TOWN DETAIL Every town has a detail page with historical photos, description,founding and abandoned years, peak population, county, coordinates (tap to copy), satellite view, nearby towns with compass bearings,and direct navigation to Apple Maps. ROAD TRIP PLANNER Build a road trip by adding towns with the car button. The app optimises the route automatically using a nearest-neighbour algorithm, shows a dashed route preview on the map, and sends the full multi-stop driving route to Apple Maps in optimised order. SAVED, VISITED & FIELD NOTES Heart any town to save it. Mark towns visited and give them a 1–3 star rating. Write field notes on each town — access conditions, what you found, travel tips — all saved privately on your device. Sort your favorites and visited lists by name, state, type, distance, or rating. Export any list as a CSV file. STATS & ACHIEVEMENTS Track your exploration with a stats screen, milestone progress bar, and 16 achievements across four categories: discovery milestones, content, geography, and town type (Miner, Rail Rider, Lumberjack, Oil Baron, and more). FULLY OFFLINE. ALWAYS. The complete 16,000+ town dataset is bundled inside the app. Works in the middle of the desert, in a canyon, at the end of a dirt road — anywhere you actually go to find ghost towns. No cell signal needed. Your notes, favorites, and visited list are stored on your device. No servers. No tracking. No cloud dependency.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
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.
