  • Great tool to have

    By Homanta
    Very handy to have at your disposal. Keep logs of vehicle for comparison when something goes wrong. Able to research trouble codes so no surprises at the mechanic.
  • Great App

    By NJGinn3
    Overall the app is fantastic, if all your wires are connected properly and there are no blown fuses, This little sucker will read anyting and everything you ask it to. Only thing I can say bad about it, is it doesn't tell you where your corroded plugs, lines, wires are in order to get to other gauges reading.(That was a joke fellas).
  • Not working

    By LiquidDragon
    I have an iPhone 7 plus and downloaded this app and purchased the add on for a 2016 Toyota Tacoma but it won't let me download it to the app.
  • Amazing app, great UI, great customizability

    By Dawwx
    I originally used a free app to work with my OBDII wifi reader and was disappointed. I decided to buy this app and will say it is well worth $10. The UI is beautiful and the customizability of what stars you would like to display is incredible. The amount of detail in how the dash readings will look graphically is well beyond my expectations for this app. The app connects to my OBDII reader noticeably faster that the free app I was using before (OBD car doctor). The diagnostic tool is very nice as well and shows all engine codes. Highly recommend this app.
  • Cool unit works great and same as expensive models.

    By Curtman432
    Remember to use a "wifi" software app( not Bluetooth). I found OBD Fusion works well with the unit. Cool to watch all monitors and diagnosis on motor to find problem and I am not even a mechanic.
  • Awesome

    It reads my VIN # correctly but doesn't give me the correct vehicle to select. Only option is Lexus and Toyota but I drive an Infiniti. Please help... Update - After clarification from developer I have updated my rating to 5 star! App is greatly designed
