    Easy to use, provides more information then most people need .. which is good.. I have used alot of different obd2 software and apps.. with this one there is no learning curve.. Doeant matter if you're 6 or 106 yeaesnold.. Anyone who owns an obd2 reader can use this app with ease..

  2. anissa ani-avatar

    Obd mary is very nice design app. App seems to be working as expected, very easy to use, and the interface is nice and simple. I thimk this is one of the more simple app amd was easier to use. Great dashboard and features i can have all my gauges in one place. Work just as it should.

  3. A Google user-avatar

    Does not work. And when looking for solutions the obd Mary recommends to use another app if it's not working.

  4. Neil Turner-avatar

    The only problems I have had is measuring miles per gallon which doesn't seem to work properly and it seems to think the fastest I have driven is 108 mph which is a bit high.

  5. Solomon Gad-avatar

    Works well and looks smart. I also had an issue but the development team helped me out with my problem. Cheers

    Actually connects to my car, so a good start. Interface seems nice, havent done enough else to know yet.

    Clickbait. Advertising free full version in exchange for positive review, which explains high user rating. Full version not honoured.

  8. Troy White-avatar

    Easy interface. Connects quickly to my BT plug. Very handy info.

  9. Dejay Genius-avatar

    So far, allows be to monitor the sensors of choice (O2 sensors).

    Great dashboard feature I can have all my gauges in one place

  17. derek m-avatar

    App works great. I use it on my 20 Silverado with the 3.0L duramax and it works great. I haven't had any codes yet so I can say how well that works (thankfully) but the dash board works great and it's super easy to set up and get connected. Definitely recommend.

  18. Daniel Miller-avatar

    Used the free version then upgraded to paid. I am delighted with the way it works. Diagnosed and cleared a troubling fault for far less than cost of a dealership scan which more than paid for cost of software and dongle combined. Software is pretty self explanatory. 2007 Pontiac G6

  19. Alan Cerezo-avatar

    Nicely designed and user friendly

  20. Simon East-avatar

    Great app, allows the data to be presented in a number of different formats via custom dashboards, in addition to this it logs trip data using the phones gps and records fuel consumption and trip costs, compatible with Mazda MX5 ND 1.5 fitted with a suitable OBD bluetooth interface

  21. John Castro II-avatar

    I think this is one of the more simple apps and way easier to use. Unlike the other ones actually connecting to the module is not a pain like most of the other ones are. 5 star

  22. justin stein-avatar

    So far so good everything seems really great easy-to-use design theme everything everything you need to get the job done to find out what you need to get the job done

  23. Mike O'Connor-avatar

    I thought the app is pretty.user friendly and has some pretty neat features. I use it mostly on my 2002 Nissan Frontier and it looks pretty cool on my after market radio.

  25. David Clark-avatar

    I must be unlucky. Plenty of data missing. What little is there appears to only be being polled every 3-4 seconds seconds at best, which is utterly useless. Uninstalled.

    This is by far the best OBD2 app. Most apps just don't work and the rest that do connect are not able to read all the data.

  60. charles eboka-avatar

    Simply awesome. Works very well.

  61. Mel Ellington-avatar

    this app refused to quit when I chose to quit all my apps. there's no obvious way in the app itself to quit. and it continues permanently to display an icon in the top-left of my Android screen with no way to remove it without uninstalling the program which is what I'm going to do right now. I highly advise not using this program unless you prefer to have this program running permanently on your phone.

    Obd Mary is surprisingly simple to use. Provides good instruction to get you connected and started. Similar to Torque if your familiar with apps like that. Double thumbs up. Allow for specific ECU strings as required by my 2003 Totota Prado. Good work.
