5 stars: Am I missing something? I've installed this app 3 times and it doesn't do anything. It's just a screen with a list of available Bluetooth devices.

5 stars: This app is so easy to use with any Prius! Just be sure you have the right OBD2 adapter. This app tells you which one to buy, too! You can find your error codes and reset them too, even while driving. This is useful when your HV battery is starting to fail until your new one comes in. You can also disable the annoying reverse bus noise and seat belt beeping.
4 stars: Great app, showing useful metrics and helping understand what's going on inside my Lexus. Not giving 5 stars because the app is not working in background (minimized) or with locked screen (can't override temperature for whole trip without draining phone with screen on). Would be great and extremely useful to have that app working in background continuously if started and connected.
3 stars: It could have been great, had they offered a trial test of the battery maybe here is the life expectancy, but give me $5 and I will tell you how each module is, or one time test. I would have probably not rated or 4 star if it said $9 is the only price for running any battery test. Now I have odb2 and the software is almost just as expensive.
3 stars: Works well but have not ...
