  • Great app. Needs more add-on

    By Jbugge32
    The app works great! Comes with great features out of the box. Easy and simple to use and the live data is accurate and quick! Only reason for 4 star rating is because you can only get advanced diagnostics through in-app purchase for certain manufacturers which I found through searching around on the internet. Other than that. Highly recommend the app!
  • Chevy Ambulance

    Will not connect to a 2013 Chevy 3500 Ambulance using a veepeak ble adapter.

    By kieros987

  • Hard to use. Where is 1/4 mile?

    By Chowabbajack
    I bought this app to use to measure my performance times, as they claim to be able to do in the description. This app is unpolished and not easy to use for a beginner. I was not able to find the appropriate displays for what I want. I'm sure it has a lot of information, but none of it is easy to get to.
  • Need more Pids

    By milmasks
    There’s no Pid for transmission temp for a 06 Chrysler 300. Also can’t figure out how to read fuel pressure pretty annoying!
  • Lexus gx470 transmission temperature monitoring

    By ADM1335
    Very easy once you purchase the extras. Super easy to set up each sensor sensor 1 is the pan and sensor 2 is the torque converter
  • Frustrating...

    By jerzee.george
    This is a frustrating piece of junk software. It worked first time with Kobra scanner. Now even though WiFi signal. No connection. Very difficult troubleshooting instructions. Plug and play anyone???! This was a waste of $$$.
  • Where is the reset button?

    By 76nba
    Reads diagnostic codes OK, but I can not find the button to reset them. I’m a bit disappointed with this. Ad says this feature is included.
  • Great for the $ works on 4S iPhone

    By Jetinjeff29r
    Buy this and and a Blue tooth OBDII reader and your pretty well set. Live data. Switch between OBDII compatible vehicles. It knows which one you are plugged into. Only one I found at the time that did Blue Tooth for IPhone in this price range. Works on my old 4S
  • No customer support or response.

    By burgieman
    This app was recommended by several WiFi dongles so I bought it. It doesn’t cover my 03 Dodge and there is no way to get a refund or a response from the developer. It also consists features that are free in other free OBD apps. Don’t waste your time.
