The app requires a Wi-Fi or or Bluetooth 4.0 (Bluetooth LE) OBD2 ELM327 compatible adapter (device) to work. ELM327 devices plugs into the diagnostics socket in the car ang gives your phone access to car diagnostics. Recommended adapters brands: Kiwi 3, Viecar, V-Gate, Carista, LELink, Veepeak. If you buy one of the cheap china OBD2 ELM327 adapters from ebay / amazon, then make sure it’s not marked as v.2.1. This adapters are supported, but they have lot’s of bugs. PLEASE NOTE: Vehicle ECUs vary in the amount of sensors supported. This app can’t show you something, that is not provided by your car. Attention "bad" adapters! We faced the problem, that some adapters (often cheep Chinese clones), can’t connect to the smartphone or the car. Some of them can even make your car engine work unstable, often lost connection, increase time lag when reading data. So, we recommend you to use genuine ELM327 or recommended adapter brands.
