  • Lovely app, but...

    By DevinLeFevere
    I love this app. It’s nice on the eyes and quicker than most. My main issue is the random disconnects using the Carista BT. Anytime I leave the main pages to let’s say check boost and then swipe back the app always disconnects.
  • Subaru?

    By TheBealler
    Do you plan on getting enhanced diagnostics etc or other add-ons for Subaru?
  • Awesome diagnostic tool

    By pleasently pleased in LA
    Had everything connected and pid’s I wanted to monitor up and running within 30 minutes. I have grand total of $40 invested between the Bluetooth dongle and app purchase. Was more cost effective than a stand alone OBD scan tool. Used with veepeek Bluetooth EL dongle from amazon and an iPad Pro.
  • Missing one thing

    By Sammy824
    I would have marked 5 stars. But it’s missing one vital part. CAR PLAY. It would be amazing if you could view on your dash without having to look at your phone. Other than that everyone should have this
  • Clear Code doest work

    By eliasgebre
    The clear code is not visible on my app. Does this app have clearing code feature?
  • Don’t connect to my IPhone

    By Octoberskys20
    It will not even connect with my iPhone, I got the VeePeak, because it was suppose to work with this app, and they do not communicate at all. My buddy phone picks it right up, I can get the app to find or connect to it, or when I able to connect to it with my phone the app drops the connection. Nothing works, SHOULD NOT BE ON THE APPS STORE.
  • Great detail and just what I needed

    By Discojon54
    Helped me troubleshoot ABS issues on a Ford. Developer question - Do you have a way to add multiple vehicles to the app so I can store data on more than one car?
  • Awesome

    Love this one
  • Reset engine light?

    By Actualccb
    I paid for this after looking at a host of apps, looking for one thing. Read codes and reset the light if necessary. All of them display codes but resetting the engine light is elusive. Auto Doctor comes close but to add reset you have to subscribe. I am against recurring fees as much as possible. I finally found and paid the $10 for this app and am glad I did. Solid Support and no subscription fair pricing. Cheap insurance for an innocuous engine light when you want to be able to know if something real goes wrong. Plus there is a lot more.
  • Great, but I have a suggestion

    By Disgruntled fisherman
    Love this app, teamed up with a high end OBD reader, the average consumer gets a really high level of monitoring and diagnostic. I have worked in heavy diesel maintenance for a very long time, primarily on CAT mining equipment. This gives me the ability to track operating stats and track component degradation. One thing I’d love to see, setting log data for individual vehicles, say I have one vehicle, OBD reader can pick up some sensors, but another vehicle can monitor others. I’d love to be able to set specific logged data for individual vehicles. So I don’t have the wade through the mass data deleting the zero reading columns to get down to the useful information
