  • Way too expensive

    By JJMick6
    Product does what it says it does but there’s no reason it’s $40 a year! I bought the device for $30 and one year pro and made the adjustments I needed to in my car. That’s $70 plus another $40 for year two. This product is not worth $110+ beware of autorenewing subscriptions!
  • Amazing

    By Dragong352006
    Got questions ... when you gonna be able to update so we can customize Nissan Rogues ? I hope you do :)
  • It’s ok, but doesn’t worth its price!

    By Will_074
    40 bucks for this is unreal, the app it self is okay. But for the price we should have more options instead windows/lights and door to be reprogrammed. My Audi A3 could be reprogrammed on how I want to lock and unlock, windows, lights (which was cool) but it doesn’t justifies the price! It does reads hidden codes (which is cool) but again 40 bucks nahhh I’d say for 9,99 it’s okay, and they do have this price but for a week lol (see they think that this thing worth like gold). Nice try, I took advantage of the free week that they gave me and could do everything I wanted during this time. Even after finished I said ... okay I’ll buy it cause it was cool, then 40 bucks lol (nope) 9,99 per year and I’ll be here buying and also giving the 5 stars.
  • Used to work great.

    After one of the updates stopped working. Terrible customer support
  • 2015 Audi A3 Inspection Reset

    By Akpark
    This product was fantastic for what I needed it for. I changed my own oil and replaced my spark plugs but couldn’t clear the “inspection due” notification. Paying $9.99 to clear the message as opposed to paying $400 to service the car at the dealership is a no-brainer. Saved me a ton.
  • Disappointing

    By IT Industry CEO
    I purchased the OBD2 adaptor and used it once. It reported that all the running lights of my car were faulty, when they were all working correctly. It also failed to reset the engine warning light, produced an error internal to the app and requested that I send a narrative error report to Carista. I am disappointed that an app this costly and its associated device do not work out of the box. I will be returning the device for a full refund.
  • 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.
