OBD2 Scanner by Motorvet

Motorvet explains in plain words what your car's engine computer reports. Plug a Bluetooth LE OBD2 adapter into the OBD port, connect it in the app and run a Quick Scan: stored, pending and permanent trouble codes, the check-engine light, emissions readiness, freeze frame data and the VIN when the car reports them, plus live values such as coolant temperature and system voltage. Reading and explaining trouble codes is free. What if I only have a code, not an adapter? Type it in under Scan > "Look up a trouble code". Motorvet shows its standard title, what it means in plain words and its system. The library explains many common codes, with more for diesel engines: glow plugs, particulate filter, EGR, NOx sensors, boost pressure. Manufacturer-specific codes are marked as such; their meaning is not guessed. The lookup is free; the last five codes stay on your iPhone only. What does a scan tell me? Each scan ends with one of four summaries, such as "Further inspection recommended", based only on what the OBD port reports at that moment. Every flagged item has "Why this is flagged". Does it help when I buy a used car? Park the car, ask the seller for permission and start the Used Car Check. Enter the dashboard mileage, add a photo and notes if you like, and see what deserves a closer look: incomplete readiness monitors, a recent reset of the diagnostic memory, permanent codes without an active fault, pending codes. Signals, never proof. The review on screen is free; the shareable PDF report needs Pro or a one-time Used Car Report. What does it not do? Standard engine and emissions data only: no ABS, airbag or transmission details, no coding, no service resets. Clearing codes, the only write function, needs your confirmation, the engine off and the car standing still, and is never offered in a Used Car Check. Do not use the app while driving. What do I need? A Bluetooth LE OBD2 adapter (ELM327/STN-compatible), sold separately; connect it in the app, not in iOS Settings. Adapters with Classic Bluetooth (paired with PIN 1234), Wi-Fi and USB adapters are not supported. A car with OBD-II/EOBD: in the EU generally petrol cars from about 2001 and diesels from about 2004, in the US from 1996. Some cars report fewer values, electric cars little or none; US cars that use only SAE J1979-2 are not supported yet. Compatible adapters: https://motorvet.taleppo.com/adapters. No adapter yet? Demo Mode shows the app with labelled sample data. What stays on my iPhone? Everything about your car: VIN, codes, scans, mileage, photos and notes. No account, no advertising. Usage statistics are off unless you switch them on in Settings > Privacy. What is free, and what is Pro? Free: Quick Scan, code explanations and the lookup, readiness, freeze frame, Simple live data, one vehicle, the Used Car Check on screen and clearing codes. Pro (subscription, 1 month or 12 months): unlimited vehicles, full history with comparisons, trends, advanced live data and unlimited PDF reports, including Used Car Reports. The Used Car Report (one-time purchase) unlocks the PDF for one Used Car Check on this iPhone; as a consumable it is not restored on another iPhone or after reinstalling, and unused credits are lost when the app is deleted. Export the PDF to keep it. Payment is charged to your Apple Account at confirmation of purchase. Pro renews automatically unless cancelled at least 24 hours before the end of the current period; renewal is charged within the last 24 hours of the period. Manage or cancel it in your Apple Account settings; deleting the app does not cancel the subscription.
