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
TesoroBoard turns your iPhone into a beautiful external instrument cluster for your Tesla Model 3 and Model Y. Mount your phone, connect over Bluetooth, and see everything that matters at a glance — speed, battery and range, power, energy consumption, gear, cabin temperature, tire pressure, and the time — in a clean, glanceable dashboard built for driving. WORKS 100% OFFLINE TesoroBoard talks to your car directly over Bluetooth Low Energy (BLE). There is no cloud, no login, and no internet connection required. You can put your phone in Airplane Mode and leave only Bluetooth on — TesoroBoard keeps working. NO GPS, NO TRACKING TesoroBoard never uses GPS or location. It reads vehicle data straight from the car. Your location is never accessed, never logged, never shared. LIGHT ON BATTERY, COOL TO THE TOUCH Because it avoids GPS and cellular/Wi‑Fi networking, TesoroBoard sips power. Your phone stays cool even on long drives, so you can keep it mounted all day. YOUR PRIVACY, RESPECTED I do not collect, store, or transmit any of your data — period. No analytics, no accounts, no ads, no third parties. Everything stays on your device. CHOOSE YOUR LOOK Switch between multiple dashboard styles: • Modern — a bold digital speedometer with side panels • Sport — twin analog gauges for speed and power • Classic — an elegant Model S/X–inspired cluster Pick High‑Performance or Standard to match your car and the gauges scale perfectly. Metric or imperial units, 11 languages, portrait‑mount or landscape. FOCUSED, NOT BLOATED TesoroBoard does one thing and does it well: it's a great instrument cluster. No feeds, no gimmicks, no distractions. And we're just getting started — more beautiful, customizable dashboards are on the way. COMPATIBILITY Designed for Tesla Model 3 and Model Y. The first time, you'll register the app as a Bluetooth key by tapping your key card on the center console — just once per car. — TesoroBoard is an independent, third‑party app and is not affiliated with, endorsed by, or sponsored by Tesla, Inc. "Tesla", "Model 3", and "Model Y" are trademarks of Tesla, Inc.

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.

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.
