Ratings and reviews

It's all really rather random. Sometimes it records trip data sometimes not. Sometimes it creates battery test results without prompting which if it's own trip data is to be believed would have been while I was driving. Sometimes it won't connect to the device at all. At the end of the day leave me wondering if the data it generates is random or can it be believed?

If it's not one thing then it's the other. Just a constant headache! None of the tests work as they should. Even if the engine is off it shows that it is charging? All of the data that was collected is either missing or just shows a flat line. It's like it's connecting to the battery meter but without Gathering data. Symptom of this is that the temperature gauge shows a constant for example 20° throughout the day.

The app keeps disconnecting when "mobile data" is on. After turning off "mobile data" and restarting the app, the bluetooth connection works as it should.
