1. Very easy to read menu and results.Full page ads, ads at the bottom of screen, must pay extra to read basic codes, and still takes 10 minutes to scan for errors.

2. It really only tells you what the problem is and that's all.The app would not connect to the ECU without data... I have two Galaxy j7s, same exact model, so I put this app on the one without data to act as the scanner and it would time out every time... Tried it on the phone with data and it connected right away... What gives? ALSO: It will read the codes but you can only see 1.

3. I now get a screen indicating that I need to purchase the full version to get this functionality.App picked up my generic obdii sensor right off the bat.

4. With the last coupe versions the screens have changed and the screen to clear codes no longer is available .

5. With more recent versions I can still read codes but am no longer able to clear them.

6. When I first got this App I could both read diagnostic codes and clear them.

7. Highly recommended.I tried four apps but this is the only one that recognized my Subaru Bluetooth despite the fact that my phone claimed that it was connected for each OBD app.

8. Avoid if you are just looking to pull CEL codes.My Samsung Galaxy S21 complains about this app "overloading the system" every day when it's not even in use.

9. I got the full version recently and I am too excited to see the full potential of this appI downloaded this app just for coolant temp info.

10. The app is intuitive and have good graphics design which make reading information so much easy and clear.

11. I was looking for a replacement for "Dash" app that went dark a few years ago, and I think this will do most of that with the trip, sensors, and even optional logging.I used the application with Toyota Corolla 2010.
