Carista OBD2

I've had this app installed on my phone for years. When I first installed it I remember making changes to my Toyota for free. The next time I tried the app it required a purchase. No problem. I buy almost every app I use. Figured I would buy next I used. Price doubled. Starting saving my Play balance. Price doubled. It was up to $20 last time I checked. Expensive, but still on my list. Opened today to buy...$40 a year. Yikes. My fault for waiting, but wow. Insane. $10 one time also insane. Uninstalled.

I get it, I really do, to keep an app running, they need money. However, it used to be free just to SEE the trouble codes. I didn't mind it when they required me to pay to reset the codes or do other extra stuff, but now I have to pay to do a basic function (which, might I add, takes forever to load all the codes)? No, no more. This reminds me way too much of Gameloft. I'm ditching this tool and buying a dedicated scanner that doesn't need a cash-cow app. It was good while it lasted. EDIT: Nice try, Carista, but that isn't true. It hasn't always been a paid-for feature to SEE codes. I used this app for two years, and I could see codes just fine without a subscription until now. If you're going to try to deceive people, at least make it believable. I'm never returning to this sketchy brand. Buyer beware!

It's not true that they give you basic codes for free. Though the app allows you to turn things "on and off", i was very dissapointed when none of the costomizations took effect in my case. I am now left with a very slow diagnostic tool. As other people said, do yourself a favor and buy a traditional code scanner, if that is what you are looking for.

forced login before I can test to see if it's worth signing up for. Then they lied to me, saying that I can still check compatibility and run a basic scan. The login screen is the very first thing that happens when I activate the app. Do not pass go, do not check compatibility, nothing. Like I said, forced login. If I knew how to block a developer from ever showing up on my searches, this would be one of them.

Nice app, poor promo info. On the Carista website, it states you get a one month free trial. This is true, but only if you purchase an annual subscription (which you can cancel within 30 days). Since you can also request a refund with Google Play in the same time frame, it's not a true promo. That being said, love the functionality when used on my Audi B9 A4. Wish the app was a bit faster, but that could be the fault of the connection between the adapter and phone instead of the app.

The app itself is good. A well made product. It's a little misleading as far as the functionality as it does not exactly tell you if it's "really" available to you or not. Until you find out that it's not compatible with your car. At least there's a trial but I would be ticked off if you had to buy their OBD2 and go through the hassle of finding out that not all functionality they list aren't 100% accurate. It's more of a shortcut to already available features is all...so I canceled my trial.

For the price of the annual subscription, you can buy an actual vagcom scanner and never pay another cent. Can't recommend due to this and the fact that without pro, it won't even - show- any codes, let alone let you clear them. Lifetime for that price would be a fair deal, but as it is, it just seems greedy on their part. Also didn't receive my free trial of pro, so I had to spend 10 dollars just to find out if it worked. ( Dev lies, cheapest stand alone is 45 and resets codes, unlike theirs)

Only use this to clear my inspection due every time I change my oil. So 2 or 3 times a year. These are single use times. It's a shame you have to opt in for the full month. The last time I subscribed I didn't realize I didn't cancel and paid 6 months straight even though I didn't use it. Wish they had a more efficient billing method but I guess they make their money, banking you'll forget to unsubscribe for single use cases.

I realized I was a bit too harsh with my original review. So I am editing it, the app works just fine, the rating is reflective of their pricing strategy. I deal with Chinese manufacturers of similar things every day. Even with the tariffs, they are making a good bit of dough selling you a 60$ OBD2 dongle. This is fine I guess, because it does give you very limited ability to change a couple of options. The subscription is WAY overpriced and not worth it with no lifetime access option.

It was confusing at first to use. Nothing work except to read. Once I was in contact with support, it work after the full subscription was pay. I was able to reset a few thing on the wife car. Also found things the car did not have some option. In all, I have to say, it did save us money than going to the dealer. I recommend Carista has to post on their site to on full pay subscription will grant all option. Thanks again for the support.

It's genuinely crazy- you buy an adapter...and then they force you to buy the software subscription just to use it! After the 30 day "free trial" expires im stuck with a useless tool. And it's a lie that it gives you "basic" codes even without the subscription, it rarely might but usually it's all blocked out. Total waste of money, just get a relatively inexpensive real hardware scanner...

It got soo much worse recently that it's really frustrating to use 70% of time. I've been using it for last few years on all of my cars due to simple and intuitive interface. Tool is great for beginners and easy to use. But recently it's slow, laggy and crashes frequently. Require internet at all times. Now if stuck somewhere with no network it's basically useless. Can't even read the codes which is it's the main use. I'll wait till end of subscription and move on to alternative.

The Amazon website told me only the white scanner works on my car and iPhone. The white scanner works on my car but cannot be seen on my iPhone 14 via bluetooth. Fortunately I can see it on my Samsung A15, so finally got it to work. Advertising is annoying. I also thought I wouldn't have to pay for accessing the full service, but in the end it was discounted for the first year. The whole app experience is confusing and poorly designed until you get used to it. However, it worked in the end.

Great for simple cosmetic changes, but no longer works to disable the auto start-stop feature on my C8 S6 or SQ8- my primary reason for subscribing. No control for Matrix LED headlights, either. Great if you want to disable little things like your seat belt chime, or tach sweep on startup, but no longer very useful for VAG vehicles. edit: have contacted support, confirmed the feature no longer works.

useless for Toyota rav4. just provides very very basic report. Paid for the subscription, and it changed a lot! (a lot of nothing). still same basic report, and that's it. that's fine, but what is annoying - knowing they are useless for my car they continue pushing me for purchasing some super upgrades, new dongles which allow to send my car to the moon (till the moment I pay, and learn that is it all marketing bs.) Guys, buy something good, don't spend your money on subscription-only pos

got me to pay showing some errors only to tell me that there are no errors after I paid. whole clearly I have errors on dash which are detected correctly by other apps. scammy behaviour

I can only give it 1 star they lied and said they support Hyundai cars, I paid for the yearly subscription only to be told I needed to buy the carista evo and it would clear codes and not customize my car. Best to avoid.

Seems to be a good app Had a full rundown of engine faults with full explanation. Then cleared them all. Shows faults without subscription, but need subscription for details info and to be able to clear them.

I bought this app for my Jeep and it worked perfectly showing me codes and being able to clear them and they even being able to view live data as the engine was running and then all of the sudden the app stops supporting my vehicle and I cannot use it for anything. it is now a complete waste of money and I wish I never would have bought anything from this company and I urge you to not support this company as they can randomly just stop supporting your vehicle. ZERO STARS

APP AGAIN IS UNSTABLE!! NOW IT DOESNT RECOGNIZE MY ACCOUNT LOG IN!!! Editing review: I have reset the Carista OBD2 module by pulling it out and putting it back in. It appears to be workiing fine now. I have requested some time ago that you make the font for the TPMS reading a little bigger. The screeen has plenty of room on it but the vital numbers, the actual Tire Pressure are so small I need to take the phone out of it's cradle to read it. Every other useless font is big enough to read.
