Was great at first, but now the app is showing different readings on everything sporadically. It will be accurate at first and then start reading -70 on battery temp or 380 on battery temp, speed going from actual to 10 or 200. I tried uninstalling and reinstalling and still the same thing.

Great app and has been really useful getting used to driving my first hybrid car. Only one issue so far - I utilse mpg for fuel consumption (UK) and whilst the High Precision Fuel Chart correctly shows the instantaneous value at maximum mpg (=low consumption) when lifting off the throttle, as it should, it colours the instantaneous bars in red suggesting worst BSFC when it should be shown in cyan or white.

Don't forget to quit the app throughout the circle bar standby icon. Just closing it by swiping it off screen leaves it on in the background and it really *eats up battery.* Also, if I change the units to be displayed, it changes right back. Update: I almost certain that this app caused my traction battery cooling fan too not run out not run at high enough speed. This will destroy your battery.

There's an option in the settings screen to close automatically when the car is powered off, and fan control is disabled by default. You must enable it manually and you are responsible for its usage.
