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

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Track performance of your car in real time with virtual gauges and graphs. Troubleshoot malfunctions by accessing the on board ECU. Know what is wrong with your car before taking it to the mechanic. Don't get ripped off when buying a used car. Run our diagnostics feature and get a vehicle health score. These are just some of the features OBD Connect has to offer. OBD Connect transforms your phone into an all in one performance monitoring and troubleshooting tool for your car. ** Notice - We don't recommend using knock-off adapters as it may not be compatible with the app. OBD Connect features: • Customizable gauges track up to 100 sensors in real time including fuel economy, G-force, gear display and battery voltage. • Fast polling rate allows for a smoother and more responsive gauges and graphing.* • Read and Clear trouble codes and reset MIL (service engine light). Over a thousand codes available with description, causes and symptoms. • Metric and Imperial measures. • Real-time user-defined sensor plotting. Graph as many sensors desired at the same time on interactive graph that can be scrolled, paused. • Gauge list feature can track every sensor at the same time. • CarPlay, display gauges on car head unit. • Create car profiles and customize settings. • Freeze frame support (mode 02). • Instant horsepower, mpg/kpl fuel economy, boost pressure and G force tracking. • Read Vehicle VIN number, calibration ID and more (mode 09). • Speed limit warning: Get notified when driving over speed limit. • High oil/coolant temperature warning gives you instant notification when your car is running too hot. • HUD mode for dashboard view : Heads up display for driving at night. • Emissions test readiness. • Multiple ECU support. • Shift light. • Two themes to choose from. • Landscape mode. • High value sensor gauge notification. • Enhanced PID support for specific manufacturers (mode 22). • Fuel Economy: - Instant and average fuel economy tracking for 0-5 min, 0-30 min and 0-2 hr intervals and a detailed summary. - Long term tracking with six different intervals. (1 week, 2 weeks, 4 weeks, 13 weeks, 26 and 52 weeks). - 4 different units of measure: MPG,KPL (Km/L), L/100 Km, Miles per imperial gallon. - Interactive graph of long term data that can be cropped and scrolled through. - Export fuel history to CSV file (spreadsheets). - Other statistics: Distance travelled, average speed, money spent, CO2 produced and fuel consumed. - 3 methods of calculation available. For non MAF vehicles. • Race track package: - Real time lap data, gap delay time and position in race track using high frequency GPS tracking. - Comprehensive summary of race with lap times, speed fluctuations on track and more. - Get drag racing times (0-60 mph, 0-100 mph, 1/4 mile 1/8 mile etc.) - Load and save unlimited number of tracks onto device. - Crucial racing data including real time horsepower, g-force and a detailed driving summary. Share your results with friends. - Transmission gear information and optional shifting assistant which notifies optimal moment of shifting gears. - Customizable view that toggles between speed/rpm gauge, real time track positioning and G-sensor feedback. - Record your race in HD with gauge and track overlays. (dash cam add-on required) • Dashcam: Record smooth HD video with overlaying gauges (speed,rpm, etc), time, location (GPS coordinates) and G-force sensor in four different resolutions. You can record from 90 sensors and up to 5 gauges. • Sensor logger: You can record many sensors at the same time with 5 different refresh rates. Save graph sensor data to CSV file and export to PC/MAC for further analysis. Send real time data to TCP socket (IP Address) over network. ** NOTICE** OBD Connect is compatible with WIFI adapters, OBDLink MX+, Vgate vLinker FS/MS and the following Bluetooth LE adapters: Kiwi 3/4 PLX, Veepeak BLE, Carista BT, LE LElink and VGate iCar Pro/ pro 2, vLinker FD+,MC+ adapter.

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.
