  • doesn’t work

    not working with blue driver. you have to purchase extras to make it of any use, but it doesn’t work anyway
  • Possibly caused my car to stall

    By JoeCool Hiker
    I used this app and an OBD reader for the first time. It seemed good. After using it, I drove the vehicle without the OBD reader plugged in and the car stalled as the vehicle was moving several times. The car started right back up though. This is the first one this has ever happened to me. I don’t know if it was the dongle or this app that might have messed with my ECU computer. Not going to be using it again though. Having the car completely die as you’re moving in traffic with no power steering is not fun.
  • Saved a lot of money and time

    By OldSchoolTechie
    I was able to diagnose and repair a misaligned cam phaser on our 2012 Infiniti G37 thanks to the vehicle specific add-on support module, which displays the current cam phaser angle. What would have been about a $3000 repair, I was able to fix myself for less than $500. Dropping one star because I wish this app supported more vehicles (Mercedes-Benz for example), so that I could use it on my entire collection.
  • Works Great

    By Chasedoggy
    I have an older car with a bunch of miles on it and I use the app to understand what I need to do to keep my car healthy. I bought a new car and it has already helped me understand what is gong on with it. I highly recommend this app to anyone who wants to know what is going on under the hood.
  • EZ set up

    By CooFeet
    Easy to set up and use. One trip to a mechanic for scanning trouble codes cost 10x more than this software.
  • Works good but missing PIDs

    By Rubberman10
    Good app but i dont see a transmission temp , battery voltage gauges. Like to see a graph to view misfires
  • Legit

    By Mr. Resto
    My life saver!
  • Can’t adjust displays

    By login hell
    At first you can edit the displays but as you add more the ability to edit is lost. Sometimes issues with the communication with Bluetooth. Confusing name other apps have similar names. Keep working on it
