Q: How accuracy Trip is?
A: We have tested Trip application on some devices and cars and there may be difference between cars ECU and also with Android phones and OBD2 Bluetooth devices. There is about ~3000 different phone models in the market and we cannot guarantee that our app works with those all. There are also a lot of different car models and we need user help in order to know how our app works for them. You can use our web form or send comments via email to our support.
Currently tested card brands are some Volvo models newer than 2005, Audi, Opel, Toyota.
