### 2/5 — Useless App

*2022-08-04*

All it does is look good it is non functional, unless there are features or data missing and there are further development of this app, I can't see it being fit to be in the App Store, all it did was get my bank account, a waste of $1.49

### 1/5 — Not very good

*2017-01-21*

Connected to car was about all it did. Showed no faults although dash light on. Not able to turn light off! 😩

### 1/5 — Doesn't work with every vehicle

*2015-04-18*

Only Battery gauge works on my car. Tested it in the wife's van and works fine. Only one star because other apps work on my car, this App doesn't. Hope some update will come soon, otherwise the money was for the garbage.
