Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
EcuFinder is the online ECU and chiptuning database built for tuners, remappers and mechanics who need the right numbers before they touch a car. Look up any vehicle — Make, Model, Generation, Engine — and instantly see: • Stock and Stage 1 power & torque, straight from real dyno figures • Full engine specs for that exact variant • Available tuning solutions: EGR off, DPF off, DTC off, and more • Every read tool and method that can access that specific ECU Search by Bosch number or OE-Number and EcuFinder highlights the ECU family (e.g. EDC17C64) instantly, along with manufacturers, vehicle numbers and every compatible model — no more guessing which family a Bosch reference belongs to. BUILT FOR THE BENCH, NOT THE COUCH • Share as PDF — export a clean, branded report for any vehicle or Bosch result, ready to send to a customer or keep on file • My Tools — mark the tools you actually own (Alientech KESS3, K-TAG, Autotuner, CMDflash, MPPS, and more) and EcuFinder highlights exactly which read methods work with your setup • History & Favorites — jump straight back to cars and Bosch numbers you've searched before • 9 languages — English, Portuguese, German, French, Spanish, Italian, Polish, Romanian, Russian • Light & dark themes ALWAYS ONLINE, ALWAYS CURRENT EcuFinder V2 pulls data live from our database. New makes, engines and tuning data show up automatically — no app update required. No account. No sign-up. No ads. Open the app and start searching. Free to use. EcuFinder — know the ECU before you plug in.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

Intermediate
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.
