Evidence scope: No current overall US chart position is available. Category-chart positions shown in discovery are a separate scope. Revenue is a directional model estimate, not verified earnings.
A product spec, screen plans, and build steps for your coding agent.

Combine features and design from your favorite apps.
Your first Build Kit is free with a verified email.
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.

Plan a route with every stop in the right order — then look down the street before you ever drive it. GPS Maps turns a list of places into one efficient trip. Drop in your stops, let the planner reorder them, and follow spoken turn-by-turn directions from one to the next. Each stop checks itself off as you arrive, so you never touch the phone while you're driving. PLAN A TRIP WITH MULTIPLE STOPS • Add stops from search, straight off the map, or from your saved places • Tap Optimize and the app reorders them into the shortest trip • Drag any stop to override the order yourself • Distance and time for every leg and for the whole trip • Stops check off automatically when you arrive • Finished trips are kept in your history SEE THE STREET BEFORE YOU GO • Real ground-level photos taken along your route • Full 360° panoramas — drag to look around as if you were standing there • Preview a whole route photo by photo before you commit to it • Press and hold anywhere on the map to look around that spot • Coverage is community-contributed, so it is richest in cities and thinner on rural roads TURN-BY-TURN DIRECTIONS • Spoken guidance before every turn, twice: early, then right at the turn • Automatic rerouting when you leave the route • Car, motorbike and walking modes • Live trip progress on the Lock Screen and in the Dynamic Island • Distances in kilometers or miles FIND PLACES WORTH THE DETOUR • Nearby landmarks with photos and background, drawn from open encyclopedia data • One-tap categories: restaurants, cafés, gas, parking, hotels, pharmacies, ATMs, hospitals and more • Search by voice — in any of the 17 languages the app speaks • Save a place now, add it to a trip later THE MAP ITSELF • Standard, satellite, hybrid and 3D views • Live traffic layer • 3D buildings • Map rotates with your heading SPEAKS YOUR LANGUAGE English, Chinese (Simplified and Traditional), Hindi, Spanish, Portuguese (Brazil and Portugal), French, Arabic, Bengali, Russian, German, Japanese, Turkish, Korean, Indonesian and Vietnamese — interface, spoken directions and voice search. GPS MAP PREMIUM The free version covers 3 stops per trip and 3 street photo sessions a day. Premium lifts both limits. • Unlimited stops on every trip • Unlimited 360° street photo views • Every future Premium feature, included Plans and prices are shown in the app before you buy.

Hypothesis 1
Assumption to check: Uses too much data
Validate with people who use this workflow before building.
Hypothesis 2
Assumption to check: Voice directions unclear
Validate with people who use this workflow before building.
Hypothesis 3
Assumption to check: Slow route recalculation
Validate with people who use this workflow before building.
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.
Not assessed in a Build Kit yet.
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.
