  • Great app

    By SeanxUSMC
    Works as intended and provides very useful information. Especially re: diagnostics/code reading so an owner can anticipate what repairs (costs!) will be needed. They work on refining/updating app as well. I have only used it to read codes so far, but will go further with it sometime. By getting codes specific to your car, you can research those codes and find out specific issues/fixes related to your model. This app will more than pay for itself if a shop is dishonest about faults with your car. Or, it may be something simple you can fix yourself once you research the fault code. The app is great. Works in conjunction with a separate plug-in device.
  • Needs Enhanced Diagnostics for Kia

    By BTHEA
    I’ve successfully used this app with my Veepeak dongle for years on my Jeep, for which it now has enhanced diagnostics, but I just bought a new KIA Soul and was disappointed to find no enhancements. Fix this and I’ll give the app 5 stars.
  • Incredible Ecm viewing app

    By Tcoilburner
    The app is great and I can view all the ECM data that I want to track. I only wish it had enhanced GM capabilities.
  • Waste of money

    By gkeener70
    This app was recommended by the Bluetooth OBD reader so I download it and paid for it not knowing the reader would work with several apps that actually work. This app absolutely terrible. I have no idea why there’s any positive reviews of it. First off connecting is a huge pain! Second of all once it reads codes it doesn’t save information after disconnecting so if you want to look at your phone once you’re in front of a computer there is no information you literally have to go back to your car reconnect yada yada yada it’s just horrible trust me I downloaded a free app and it works amazingly well. Do yourself a favor save the money do not download this horrible app!!!!
  • Not Worth $9.99

    By ZestyTBag
    This app is no different that similar free apps. Purchased this with the hopes of reading ABS codes as the app claims to do. Fully expected to be able to purchase an add on to do this but it was not available for Chevy/GMC.
  • Does The job

    By George Blais
    This one connects to my Carista Bluetooth adapter and delivers a wide range of stats as well as clears the error log... Have just started to use and learn it, but already it has my recommendation

    By ScottB
    Been using a few years now and I started with a WiFi unit and changed to Bluetooth. Much better! Just bought the add on pack for 2007 Toyota’s too. Would not leave home without it! Recommended.
