  • It's Good!

    By newmexguy
    I purchased another app on the App Store and I like this app much much better. It's a little difficult to get the hang of programming it but gives you back for your time. I am disappointed that I don't get an oil pressure no transmission (auto) pressure nor temp but probably has something to do with my truck not providing the information via the OBD port. It is not real intuitive but like I said - for your patience you get paid back. I have a 2009 Hummer H3T, 5 cylinder and a KIWI 3 OBD scan tool. It takes perhaps 5 seconds and it is spitting out numbers. I'm very happy with the combination.
  • Have a BAFX scanner and it won't connect.

    By PJ Armstrong
    I've been trying to connect to my scanner wifi and Bluetooth and it still won't let me connect.
  • Ford F150 ecoboost

    By Blitz1029
    Reads boost at 6psi at idle. Need to fix that. Other than that the connection is used through wifi, so cannot use internet while connected to the wifi OBD adapter.
  • Excellent

    By Phil New York
    So far working excellent.
  • A Good OBD App... Tutorial Would Help

    By twwaurora
    This is a very good OBD app once you know how it works... The warning message about not accessing the diagnostics module with the engine running does not apply to vehicles that don't supply power to the reader device with the ignition in the on position... Either more accurate messages or a tutorial would help.
  • Extremely Versatile

    By Dan Lidral-Porter
    This app lets you build a sweet set of real time dashboards. Has a little editor for styling that includes making templates, which really lets you go whole hog. As a first-time car owner it's been very helpful in understanding how my engine works by seeing how the readings relate to one another. I can even log a few readings to review later and archive as reference data in case trouble comes up down the road. Can't recommend this highly enough.
  • Awesome!!!

    By Hauberk
    Very useful and a great deal!!! I use it daily to monitor gas mileage, speed, emissions, and monitor error codes.
  • Nice app for BMW

    By Tilden2000
    My M235i doesn't have a temperature gauge. Now I can have customized gauges displayed that are missing from the car. Very easy to use and to customize look.
