  • Great product

    By Kstriper
    Works very well, I always use it to check for any issues and use it to check cars before I take them in for a smog check. Occasionally, a slow connection. Thanks.
  • Doesn’t connect

    By Seamuskrat
    The software interface looks nice. Problem is it doesn’t actually connect to any device. I’ve tried three different OBD all of which list compatibility. My friend has a different app that works great with all three. I had hoped this would be simple and easy. It isn’t.
  • Amazing App for Scan Tool

    By Jus' Groovin'
    I purchased the Veepeak OBDCheck BLE OBD2 Bluetooth Scanner and this app plus its add-on for my vehicle family. This app recommended the Veepeak scanner. Its site recommended this app. It sounded like the perfect combination for an app-based scan tool, so I got them both. I couldn't be more pleased! The scan tool, I think, is very good. It gathers the complete OBDII required data and, it appears, any extensions the vendor adds. This app is infinitely configurable. It appears to be able to collect the full OBDII set and any and all vendor extensions. However, they may require the purchase of add-ons within the app. There are two screens of "instruments" that come with the app. You can add more screens and instruments and fully customize them to display data the way you want to see it until you go blind. Looking into the settings, I can't imagine there's anything missed. I'll also add another plug for this scanner/software pair. I believe the Veepeak is the only one for iOS that doesn't connect using Wi-Fi. It connects via Bluetooth LE. Also, you don't pair it. OBDFusion connects with it directly. This makes setup very easy and, more important, it leaves your Wi-Fi, cellular data and Bluetooth untouched and available! Very nice.
  • Doesn’t pick up all errors

    By Crazy Dame
    Tested with vgate icar pro 4 adapter on 2008 Mercedes ML 350 and 2010 Nissan Pathfinder with known errors, also with the light lit on the dash indicating car issues, and both showed no errors, but did show errors on 2004 Jeep, 2017 Chevy Traverse, and 2012 Honda Civic so obviously not an adapter issue, and has to be an app issue.
  • O2 sensor T/S

    By Ford exploder
    The program does more than most OBD scanners do except for the expensive one For one I was able to trouble shoot an O2 sensor that was not reading correctly by watching the voltage live. That alone was well worth the price of the program
  • Best ODBII

    By LanPhantom
    Great app. Two wishes: 1. Enable user to select digits temp gauge. Numbers on analog temp gauge are very hard to read. 2. Add advanced in app purchase for BMW/MINI diagnostics and stuff. Would like to see battery re-initialize, transmission reset, re-initialize window module, etc. would pay handsomely for that.
  • It’s a good app to read your codes

    By gti ty
    Bought this to use as a boost gauge doesn’t read accurate says I’m getting 25psi when my car is tuned to run at 14psi wasted my money but at least I have a code scanner 😂😂
  • Nice

    By E404rb
    Between kiwi and this app, the combination works well . 2003 Subaru Outback. Easy connect. Reset engine light quickly. Just getting used to all the app features, I like the logs, and dashboard.
  • Meh

    By Blues Blues Blues
    Honda seems to be only partially supported.
  • Jeep

    By Twoodman66
    No available upgrades for Jeep. In reply. Then you should list which vehicles are supported and which are not. That would be the honest thing to do.
