It connects easily and it gives u many parameters to look at. But you need a PhD in engineering to understand it most of it. Simple ones are fine but if each included a simple explanation it will make this app the best in the market; Also another thing is that I can't email the log files or download them in txt or notepad++ files so we can easily read them.

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.

I assumed for the price I paid for a elm knockoff I'd be dissapoited then connected to this app, I was not dissappointed with the hardware and even with the basic version of this made it great but I quickly realized the developers need to eat and your asking price for a fully capable lifetime license was well within my means as well as everyone's. What you created, (not fully explored) gives back to the people, what most manufacturers guage into your wallet to take what we don't have. Ty

You can't clear/erase codes, it just saves them. Not to mention it won't connect to scan either. I keep getting (error connection) code plus no actual customer support. I paid $4 for the "premium" version too which is no different from the basic version. Don't waste your time with this app.

This was one of the best obd2 scanner apps that I've used. I use it on my win7 laptop and on my Android phone. The problem I have now is it worked fine with my ELM327 adapter last year. Just tried it again and the app connects to the dongle on Bluetooth, but gives an error as if the ECM is off and it is not. Looks like I lost something when the app was updated . I hope they can fix this because I do not want to buy a different dongle just to work with this app

Good little app to reset those pesky trouble codes. Simple to connect but a little tricky to pick the right engine... but after you figured out your engine type you are good to go. Also the free version allows you to actively monitor two simultaneous readings of your choosing.
