  • Great app!!!

    By JEFritz
    Diagnosed the check engine light on my Lexus RX 300. Love it!
  • Still Working With It

    By Bruser150
    This app has numerous options for setup and displays, but no instructions. There lots of options to monitor different parameters, but nothing (that I can find) that defines those parameters or what is monitored to access those parameters. Still, it’s a great app for monitoring your OBD II device, though I did have difficulty initially getting my phone to hook up to the WiFi.
  • Well done

    By Papi Nick
    By far one of the best apps when it comes to OBD2 data reading/presenting. Job well done !
  • Doesn’t show known trouble codes on Ram 1500

    By Rewards1
    I currently have 3 trouble codes on my 2012 ram 1500(ABS, 4WD, and traction control service codes). None of these codes showed up on their App. From what I can tell this App is not even worth the download, yet alone my $10.
  • Decent to use, horrible to set up

    By Hsjnahjjdjs
    Take me forever to get things organized and on certain dashboards. The information is nice but it literally took me HOURS to set up everything due to the unnecessary amount of options. Also no way to automatically insert multiple gauges and have them scale to the display as you add. Needs work
  • Can’t connect

    By ObeyAG
    I’ve tried everything to connect my 09 Mini Cooper S. And nothing happens. Thanks for the wasted 10 bucks.
  • Service engine light will be gone!

    By E.J.S.M.
    I have to say the app is less complicated to maneuver than I expected. I really like the fact that it can read all the Gages without my car having them, for example the temperature gage. I gave the app 5 stars but will come back if to update if anything changes.
  • Doesn’t reset MIL light

    Doesn’t reset my Honda 2005 pilot MIL light
  • Consistently does not connect to Automatic adapter

    By Sardonick007
    Problem still all over the forms OBD fusion does not connect to Automatic adapter consistently seems like a waste of money to me. No estimate of when it’ll get fixed and no remedy.
  • Blusmart wifi obd2 scanner connection

    By Frankd22003
    The app keeps saying failure to connect to my Blusmart Wifi OBD2 scanner when everything is correctly setup. Persistent failure. I followed the instruction but the problem still persist. I guessed the app hasn't been updated to work with Apple latest IOS.
