  • Doesn’t Function as Advertised

    By XtoEvolution
    Don’t waste your money on this garbage. I’ve tried applying many of the modifications listed for the Audi S3 and only a few of them work. I’d highly recommend OBDEleven over this. At least the functions listed for that app actually work and you don’t have to pay an absurd 39.99 for a years worth of garbage.
  • Too Expensive!

    By rkricketts
    As a (former) retail software developer, I understand why devs are moving toward subscription models. But $40/year is too expensive for what is generally an infrequently-used, casual-use app. None of the other apps I subscribe to, like RoboKiller and Overcast to name just two, cost anywhere near as much and I use them *far more often*. Overcast could quadruple its subscription and I’d still pay it because I use it heavily – hours per week. Its use:cost ratio is very favorable. But Carista, not so much. I’d probably use this a few times per year, that’s all. Very unfavorable use:cost ratio. Carista, as I understand, already discourages commercial use and “oversharing” by limiting the number of vehicles (by VIN) that can be tweaked. I’m fine with that. I just want to tweak our two cars, that’s all. But I want to revisit my tweaks occasionally. Offer a $10 or $15(tops) per year sub and I’m pretty sure the developer will see many more annual subs. I would sub for that. $40 is a lot for a seldom-used app. $10 or $15 isn’t. And I will not pay $10 for one week, either. That math is even worse.
  • Worked great on Audi Q5

    By Moja Fan
    Needed to reset my service due message after changing oil. Did the job. I cleared some fault codes and did a little customization. No problems. Easy to use. I did the one week payment as I wanted to support the company. Good job Carista!
  • Bad pricing, find something else

    By notTakenNickname007
    The app is used to be free for code failures check and Pro version for configuring the car, which makes sense, but now they don’t even let you see the error codes, so free version does nothing. I bought it when the pricing was different and would return their proprietary dongle if I could.
  • Overpriced!

    By Bpobill
    $10 for a week or $40 for a year? How did you come up with this? Many options didn’t work on my Audi. DO NOT buy the app until he fixes the pricing issue.
  • works fine at diagnostics for older car but

    By geminifab
    The app works fine when I want to diagnose check engine light codes on my 10 year old Hyundai - I wish it would keep a record of the recent history of thrown codes, if it has this feature I couldn't find it. Would be helpful to have that information stored to show a history of issues to the mechanic.
  • Vag450

    By Common application
    Where to start? It’s difficult to just check the app without having to think in the rest of the things involved in the app itself. The idea of having a obd2 in a smartphone is fantastic “idea” you know! to have a multi-tool handy in the reach of your pocket and all. However for several years now, developers use enthusiast people, and professionals technicians feedback to develop functional app’s. In this particular case, which at the beginning was a win-win situation for developers and customers, where many bugs were solved and new ideas brought forward however, as soon as developers had a stable version they forgot about the enthusiastic average person or the professional technicians and money comes first. This monthly subscription has been rude towards all of us that make this app possible. We the people! We never forget and the same way we help to build empires like Sears. We can choose not to be part of it anymore! Different alternatives coexist. A real Vag Scanner such as the VS450 will do most of the things this app offer for $30 US Dollar easily found In the amazing Amazon. So again what is the purpose of an app?
  • Add more old Toyota & Lexus models

    By i cant find good name
    Add Lexus IS 2nd generation..good tool over all
  • Not bad could be better

    By Dellomorgan123
    Most apps that a free connect faster than this app to your cars computer.but it does offer some features that are not Offered in other apps I wish you guys had more options for lexus /Toyota models 2015+ to bleed brakes check abs and other diagnostics . Other than that it’s a good app but definitely needs improvement
