I bought the Pro version, and it's worth the price. I'm a Smog Tech and when I need to show a customer the state of their vehicle this app displays the codes and monitors with a lot of clarity. I don't like that all the of the Freeze Frame data such as Fuel Trim information is not displayed. There had been times when Permanent Codes were not displayed. Since the last update, you need to use the Dark Theme to view the control buttons, such as the ones used to select data pids.

Does the basics better than competitors. Today my van lost the torque and eventually, the check engine light came on. Some apps require money for a single faults reset, others require a full version of the app and they still wouldn't do what you'd like. This app showed me the errors, let me reset them and eventually I could make a workaround the fault and keep driving home. Thank you so much!

Every time I run the app it finds the odb2 unit it finds the computer the ECM and then dies on the phone restart app. The real interesting thing about this is that I'm sitting alongside the highway broken. I think it's the fuel pump. But now out of the few I was looking to make work I have to get rid of this app and try to find another one. First in Play Store they all look like they're going to work until you install them then they tell you that it cost money. That's no good Google.
