  • Was doing great.

    By 05FXT
    Until one about a month after downloading the app. It no longer connects to my OBD2 plug in. Not sure how to trouble shoot. Any advice would be great. Will rate 5 stars if it starts working again
  • Solid App. Great Customer Service

    By Jason 06
    I purchased this app along with a recommended BLE adaptor and it won't stay connected to the car. It's an adaptor issue and not the app. Customer support was fantastic. The app did a ton when it was connected and will be my go to ODB2 diagnostic app. Once I get the adapter issue sorted I will update the review again.
  • Connection

    The app will not stay connected. Downloaded 2 other apps for free and they worked fine. I which I could return it.
  • Great app

    By Masdeath
    Requires some skill to use and could use a few more preset gauges and dashboard styles. You also have to import several PIDs if you want more access to sensor data in GM vehicles. Over all great app. Lag is nonexistent using an lelink ble adapter and iPhone 5s displaying 4 or less gauges. You get more lag the more gauges you use at a time, could be the software, adapter or phone, not sure which. Would like to see a Pontiac specific addition, to access some more in depth features on the pcm.
  • Great addition to “Automatic Pro”

    By HottWeelz
    If Automatic Pro doesn’t give you anything you need, THIS app will keep you busy for days creating custom dashboards and retrieving OBD data. I have one dashboard for performance. One for trips. One for diagnostics. Etc etc etc. Very packed.
  • So much data!

    This app is exactly what I was looking for and much more. Works on my 97 Grand Prix GTP and the wife's 2011 Tahoe. Can scan, log data, and even do custom PIDs. I was looking for iOS app to scan for KR and this is perfect. I normally don't pay this much for an app or leave a review afterwards, but this one is well worth it.
  • Great app and great customer support

    By Krown Mee
    Bought this app skeptical of the price, but after purchasing i fell in love. I had a few things that i saw could be improved and contacted the support team, they pushed an update quickly fixing what I wanted. For example i have an ipad air 2 mounted in my 2015 mustang. it’s mounted in landscape mode and when i bought the app the menu bar was always out not allowing full screen dashboard/performance/etc. they pushed an update quickly after contacting them. they also added 2015+ vehicle add-ons which i needed. so THANK YOU guys for making your customers happy!
  • Great app, no oil temperature

    By 5QUAR3
    Very good app. But for some reason doesn't have a way to read oil temperature...
  • Worked as described

    By Olga420$$$$
    My van had the engine light on due to a dead battery. It wouldn't pass smog without a drive cycle completed. This app led me through the process and notified me when it was ready for smog test. Great app and easy to use:
  • Does the needed.

    Works well to get information from someone other than a repairman.
