iOBD2 App Reviews

I am using this app with a WIFI OBD2 adapter. The iPhone connects to the WIFI alright, but then the app often reports no communication with ECU. There is this "No DataStream" message which is confusing, what does it mean really? No help information. When doing the readiness test, the app always crashes, sometimes it displays data for 10 seconds, but sometimes it crashes within less than 1 second, can hardly read the screen. Generally speaking the app is confusing, and requires a lot of hard navigation up and down menus, when navigation could have been implemented sideways using left/right swipe, for instance switching from the two "Readiness tests": 1-"Since last DTC Clear" and 2-"Current Drive Cycle". Another confusing thing is the message "Live data". What dos that mean? It seems to mean its working but I can see that when no data is received. So what is it. Aslo confusing the WIFI signal switching from Blue to Red. One would think that red is when something not working, but I do see it when it is working. I am still giving it two stars instead of zero because, after a lot of efforts, I managed to clear a code once, and because the app is free... cannot ask for too much I guess! Last, I tried t report the crashing bug, but there is real "support website". I found a "Contact" button on a page that I could switch to English, then wrote my report and hit Send, only to get a a page all in Chinese with a error log that was telling my message had not been sent due to some error... But I am moving away from this app as soon as I find a better one! I advise anyone to try something else first, this app is really poor!

Still broken. I can not connect to my iPhone with any combination of restarting or even manual configuration. Also can not read transmission codes which is disappointing.

One of the most comprehensive. Relatively easy to use. Some abbreviations in custom mode options that are relatively unimportant, but could have been more user friendly.

Worked great when I first got it, but when I upgraded my phone to a 6S Plus running the latest iOS it stopped connecting to the Bluetooth adapter. Three unanswered emails to tech support, and I may need to send it back. Happy to change my review if an update resolves this issue.

It seems most of the features work without paying to upgrade.
