  • Great Value

    Even including purchasing the interface, this App gives superb value for the amount of money spent. You can monitor, in real time, all of your vehicle's vital signs. Reading error codes is also intuitive and fluid.
  • Waste of Money for Toyota Prius

    By bgmcf
    Purchased app then purchased “Extra Package” for Toyota Prius. OBD Fusion said no codes, so I had to pay Toyota Service to pull a worthless code. So for Toyota Prius OBD Fusion was a waste of money and OBD Fusion’s in app purchase for “Extra Package” for Toyota was an Extra waste of money!!
  • Nothing for Chevy

    By macr88
    No enhanced features for Chevy
  • Not a fan

    By Ligarzero001
    Honestly I was trying to use it in the same way I used the torque app for android but clearly there is no way to check the transmission temperature for my carmy 2011 le regrardless of the fact that I purchased the extra features for 10 more dollars so to me it’s just a useless app

  • APP is great but.......

    By Jsheeh9427
    So the app has been working great for me. However I have one issue with it. When ever I do a FICM diagnostic it disconnects. I have a 2004 Ford F-250 6.0. 4X4. I have ran it with engine on and in the auxiliary position. Every time just disconnects.
