Generating… usually about a minute.
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.

Navigate Kruger National Park with turn-by-turn directions that work anywhere in the park — even with no signal, no data and no roaming. The entire map is already on your phone. Kruger Nav is an offline-first safari companion, built for one park and nothing else. The map, the routing engine, the wildlife guide and everything you save all live on your device — so the app works exactly the same at a remote waterhole as it does at the gate. BUILT FOR THE BUSH Offline turn-by-turn navigation. A custom routing engine plots your drive on the device, with no signal required. It keeps every route inside the park, prefers tar over gravel for a smoother ride, and warns you about closed and restricted roads. The most detailed Kruger map you'll find. Every road, river, camp, gate, picnic spot and waterhole, drawn in fine detail — with optional terrain hillshade so you can read the hills and valleys. A wildlife field guide to 240+ animals. Mammals, birds, reptiles and more, each with the best time to spot it, how rare it is in Kruger, plus diet, habitat, behaviour, conservation status and names in five languages. See the best roads for sightings. Shade the road network by animal density and head where the wildlife actually is. Plan the perfect drive. Start from a curated half- or full-day route, or build your own with multiple stops and a realistic bush ETA at your chosen speed. Read the landscape. Overlay rainfall, river catchments, flora and geology, and tap any zone to learn what you're driving through. AND EVERYTHING ELSE - Drop sighting pins and link them to a species - Unified search across places, animals and raw coordinates (DD, DMS, DMM) - Sunrise, sunset, moon phase, UV index and a multi-day forecast - Camp gate opening and closing times, month by month - Import and export KML/KMZ to share routes and places with your group - The full SA National Tree List — 1,625 trees, searchable by NTN sign number - Store your SANParks Wild Card details and export a tidy PDF card - Illustrated guides to animal spotting, sighting etiquette and Kruger's history - Over-the-air road and closure updates, with no app update needed - Switch the whole app between kilometres/°C and miles/°F PRIVATE BY DESIGN No account. No login. No tracking. No ads. Your saved places and sightings never leave your phone. The only things the app ever fetches are updated road data and the weather. Kruger Nav is an independent app, made by people who'd rather be watching the road for lions. It is not affiliated with or endorsed by SANParks. Download Kruger Nav and take the whole park with you. Note: live location and turn-by-turn navigation require GPS. Every iPhone has GPS; on iPad, only cellular (SIM/eSIM) models do — a Wi-Fi-only iPad can view the map but can't show your live location.

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.
