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.

You're doing 70 on the interstate. The tank is low, everyone's hungry, and the next big green sign is a mystery. Take this exit, or gamble on the next one? Pit Stop ends the gamble. Open it on any US interstate and it figures out which highway you're on and which direction you're headed — then lines up every exit ahead with exactly what's there: gas stations, restaurants, hotels, and sights actually worth stopping for. NO TYPING, NO SETUP • No route to enter, no destination needed. Merge on and the exits ahead just appear, counting down as you drive. • Off the highway? Pit Stop waits quietly and lights up the moment you merge. READS LIKE THE REAL SIGNS • Filter to Food and every exit becomes a blue logo board — the brands you know, laid out like the signs on the roadside. • Gas, food, stays, and sights, each with its distance off the ramp, so you know if it's right at the exit or three miles into town. FIND YOUR CRAVING • Search "Chipotle" and see the next 5 exits that have one — with miles, minutes, and distance off the exit. • Or just say it: tap the mic, speak, and Pit Stop reads the answer back while your eyes stay on the road. WORTH THE STOP • Roadside wonders get a heart: castles, museums, zoos, national parks. If something remarkable is coming up, Pit Stop tells you before you drive past it. BUILT FOR THE DASH • Full CarPlay app: exits ahead on the car screen, food and gas tabs, one-tap brand search with voice, and one more tap hands navigation to Apple Maps. GAMES THE WHOLE CAR PLAYS • Backseat Games turn the drive into family time: kids join from their own phones at play.pit-stop-app.com — no app needed — and the CarPlay screen becomes the live scoreboard, so even the driver plays, hands-free. • Exit Bingo deals cards from real places at the exits ahead. You win by looking out the window. • Dinner Draft: the car votes on the next five food exits and Pit Stop navigates to the winner. • Plus Over/Under, License Plates, and Mile Marker Showdown — on any road, not just highways. WORKS WHERE SIGNAL DOESN'T • Every interstate exit in the lower 48 + DC — 20,000+ exits and 700,000+ places — ships inside the app. Good stops. Great trips. Exit data © OpenStreetMap contributors. Pit Stop is not affiliated with the brands shown; logos identify businesses near exits.

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.
