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.

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.

VINDecoded checks any car by VIN or license plate, and with a Bluetooth OBD2 adapter it reads the engine too. Decode a VIN at no cost, then see what matters before you buy: open recalls, market value, listing history, accident and title checks, the window sticker and the check engine light. Own a car? Keep it in your garage with its maintenance, recalls, value and engine checks. Run a lot? Track inventory with your team. BUYING A USED CAR • VIN check and VIN decoder for any 17-character VIN: year, make, model, trim, engine, transmission and equipment. • Scan a VIN barcode, or snap a photo of the VIN plate, door sticker or windshield. • License plate lookup: find a car's VIN from its plate and state. Vehicle data only, never owner details. • Accident and title checks: reported accidents and damage, title brands, salvage, flood and lemon records, odometer problems and previous owners, where records exist. • Listing history: past asking prices, price cuts and relists, with days on market. • Market value, trade-in value and what a dealer pays versus asks. • Open recalls, safety ratings, complaints and service bulletins. • Rebuild the original window sticker from the factory build, with options, packages and MSRP. • Ask AI anything about the exact car you're looking at. • Compare cars side by side, with notes, tags and inspection checklists. OBD2 SCANNER: CHECK THE ENGINE Plug a Bluetooth LE OBD2 adapter into the port under the dashboard. Reading the car is free; the adapter is sold separately. On iPhone, Wi-Fi and classic Bluetooth adapters can't connect. Most gas and hybrid cars and light trucks from 1996 on have the port; electric cars report less. • Check engine light and trouble codes in plain English, with how urgent each one is and the usual fixes. • Before you buy: see if the codes were cleared recently, if the VIN the engine computer reports matches the listing, and if the mileage fits the car's listing history. • Emissions test readiness, and battery and charging voltage. • Add a car by reading its VIN from the car. • An Engine light for every car in your garage, with each check saved. OWN A CAR • A garage for every car you own: open recalls, specs and value in one place. • Maintenance tracker and service log with what's due next. • Fuel log with MPG and cost per mile. Snap the pump or receipt to add a fill-up. DEALERS AND PROS • Fast VIN scanning for auctions, trade-ins and the lot. • Inventory with stages, costs and asking prices, and a shared team workspace.

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.
