Supported OBD Readers
Last Updated: October 18, 2026
An OBD reader plugs into your car's diagnostic port and sends live engine data to Trackd over Bluetooth. With one connected, Trackd shows a rev counter and engine temperatures during a session, and records your revs so you can add a rev counter to your videos. The readers below are supported.

| Veepeak | OBDCheck BLE / BLE+ | Recommended |

Notes
- Your car: Your car needs to be OBD-II (called EOBD in Europe). In the UK and EU that's most petrol cars from 2001 and diesels from 2004; in the US, cars from 1996. Electric cars often don't report engine data.
- What you'll see: This depends on your car. Revs, throttle and coolant temperature are reported by almost every car; oil temperature only by some. Oil pressure isn't part of standard OBD-II data, so it isn't available on most cars.
- Buying a reader: Check the listing says Bluetooth 4.0, BLE or "works with iPhone". If a reader works with Android but doesn't appear in Trackd, it's most likely Bluetooth Classic.
- Connecting: Plug the reader into the port (usually under the dashboard on the driver's side) and turn the ignition on. In Trackd, open the map, then Devices › OBD reader. There's no need to pair it in your iPhone's Bluetooth settings. A reader you have used before reconnects automatically next time.
- One app at a time: Only one app can use a reader at once, so close any other OBD apps if it won't connect.
- Battery: Some readers keep drawing power while the car is off. Unless yours has a sleep mode (like the OBDLink CX), unplug it if you're leaving the car for a few days.
- Not connecting? If a reader does not connect, please contact us and tell us the model.
- Trademarks: Veepeak, OBDLink, Vgate, vLinker, Carista, LELink, OBDeleven, BlueDriver and FIXD are trademarks of their respective owners. Trackd is not affiliated with or endorsed by any of them.
