  • Great app!!

    By Hillelllevans007
    Quick connection and on the point diagnostics.
  • Awesome features.

    By jetta1.8T
    Great app. Awesome features. I just wish the sweep of the needles or the digital readout a were smoother.
  • Worked for a little while

    By Thebigbigrig
    Don’t waste your money... I did. Connected to my device a few times and now just won’t
  • Good customer support

    By Accent industries
    I purchased this app for my 2006 Prius, initially I could Not get it to connect to my veepeak Bluetooth dongle. I did not realize that my particular device was only Bluetooth and not Wi-Fi. I contacted customer support and they got back to me almost immediately. They directed me to select Bluetooth(BLE) In Communication section under preferences for my particular unit. The app connected to the Bluetooth device and recognized my vehicle immediately and now it’s working great!
  • Seems pretty cool

    By Geddy'sUncle
    Had it in my little Ram1500 ecodiesel only since yesterday. I can now monitor boost pressure, exhaust-gas temps before and after turbo pretty easily. There are a couple dozen other parameters I could watch if I do chose. I haven’t demanded that many additional interrogations and answers, so, I don’t know what it takes to overload it and get slow updates, but, for what I want to watch, this little system seems to work pretty well. Wrote those first paragraphs a few months ago. Since then, I’ve used it to identify and clear a “DPF” clogging code, due to a couple of cases of excessive idling time. Updates could be quicker, though. Nowhere near as fast as analog.
  • Wasted 10 dollars

    By anandbaba
    Bought this thinking it would work with Acura MDX 2017 and foseal WiFi adapter. It never connected to the vehicle. It doesn’t work with all vehicles. I see a lot of people have thrown their 10 dollars in trash.

  • Excellent App

    By Kringlekrush
    Been using this for about a month with my ‘11 Mini Cooper S in conjunction with a Bluetooth OBDII adapter. Most of the time I use it as extra gauges especially coolant and boost. It did help me diagnose my car when a coil decided it didn’t want to work anymore. I normally don’t buy apps but this one has already paid for itself
  • Can’t tell you how much this has helped

    By frankiejr
    Can’t tell you how much this has helped me diagnose issues without a mechanic. The money I spent is a tiny fraction of what I saved by doing the work myself.

    Unbelievably great app, let alone for free! Any single of the multiple tools included in this application are really cool. I would say overall this app is a better data logger, data monitor and gauge/indicator package then it is a diagnostic tool. As far as BMW diagnostics are concerned, it only gives you the generic errors with none of the proprietary insights that you get from BMW dealership level tools. But for 90% of the users it perfect. The performance screen is also really cool as well. I highly recommend taking advantage of the app's dropbox link so that you can download all the data at this application generates onto your PC for both current and historical analysis. Well done, and thanks a lot!
