Ok... 🤔

Are you actually fully "supporting" Honda, or are you secretly biased against it, and pushing fake service? 🤔

Because there's a statement that you're in bed with Toyota.

Why did it take you years to support Honda, aren't you "interested" in reliable cars? 🤔

terrible

absolutely terrible, waste of time and money. can’t even read a fault code without paying for a subscription. i’ll stick to OBD11

Not up to the high claims and not worth the money

I bought this device after watching loads on youtube claims done by those people who get paid referral fees. Well… it arrived within two days or so to say the next working day. I was very keen in resetting feu faults and modules on a Renault Kadjar after replacing a completely dead battery. To discover that nothing would reset correctly, no customisations available, not even the oils service reset present. Tested on a neighbour Ford, nothing extra could do that the could be done directly from car dashboard. Tested on another car, an Audi Q5… it could only do a passenger seatbelt de-activation. After all those proving tests I came to the conclusion that the ELM327 saved me and done all the resets needed on each module. To add on top of the situations explained, at the beginning, because the app didn’t had anything for my car model, I’ve sent to CARISTA/PRIZMOS a scan file of all modules in the idea and hope that they’ll work out something for my model in everyone’s benefits. After writing to them and receiving the promise that an answer will come within 24Hours… well nothing received even after 2 other requests for refund, am here giving a clear, honest review/opinion/experience description, so other people don’t go though this frustration. I hope they’ll keep the 14 days return promise and reply within time for me to return it without any hassle .

Waste of money

Paid for a month of premium to be able to export data of RPM and other aspects of my drive to support a warranty claim, and all you can do is read live data. What a waste of £20!

Used once, now won’t work.

I paid for a monthly subscription and downloaded this app on August 5th, 2026. I used OBDLink MX+ scan tool with it to program the new TPMS on my Toyota Tacoma successfully. The app recognized my scan tool perfectly. I tried using it again with the same scan tool on my GMC Sierra, August 30th, 2026 only to find out that it won’t recognize my scan tool now. “Failed to connect,Report problem”… so I reported it and was told by app support that it didn’t work with my scan tool. I told them I used it less than a month ago and it did work. They said “thanks for clarifying but the OBDLinkMX+ is no longer supported”. Thanks, but no thanks! $20 down the tubes! So I decided to do a review. I WOULDN’T recommend this app to anyone. UNSUBSCRIBED!

Não liberou algumas funções na BMW

A princípio comprei o plano semanal, mas não liberou algumas funções de personalização na BMW 328. Daí comprei o plano na promoção 229 reias, porém continuo sem liberar as outras funcionalidades e só ficou para os diagnósticos. Podem me ajudar? Mas o app é incrível. Parabéns!

Anfangs tolle App, leider wird mit aller Gewalt versucht dem Kunden den eigenen Adapter zu verkaufen

Ich nutze die App nun schon fast ein Jahr mit einem OBDlink MX+. Leider wurden mit der Zeit immer weitere Funktionen gestrichen, welche nur noch mit dem eigenen Adapter von Carista möglich sind, früher aber durchaus durchgeführt werden konnten (z.B. Handbremse Reset Ford Focus EZ 2020). Technisch gesehen ist der OBDlink-Adapter dem eigenen von Carista überlegen, hierbei wird einfach mit aller Gewalt versucht, dem Kunden ihren Adapter aufzuzwingen.

Seit dem letzten Update – wohlgemerkt ohne Ankündigung hat man den Support des Adapters beendet, sprich, mein Premium Abo ist nun wertlos…

Das ist unterste Schublade.

No customer service gets back to me how to resolve app not showing functions

I bought this to register a new battery. Paid for the $20 month. Shows my car is compatible but doesn’t show battery registration option. Reported, emailed but no help besides useless ai feedback. App doesn’t even show whether I have the subscription but the website shows I don’t. However the App Store most certainly shows I paid for it and I logged in and out. Prob hours of trouble shooting trying to get it to work. I don’t recommend this OBD.

Does not do anything

Checked the Carista website, my car model is listed as compatible.
Bought the app and was charged twice for the same app.
Tried to get it to work on multiple occasions but could not access any settings in my car.
3 incident reports logged and multiple chats with customer service and still did not work.
Denied a refund even though I was mis-sold the product.
£25 down and about 6 hours wasted.
Buy this app at your own risk.

Excelente aplicação.

Aplicativo muito bom, sugestão: se for possível uma nova versão, com mais modificações em veículos com PQ25 do grupo WV, exemplo gol a partir de 2018.

Dont get this scanner

Need subscription to do anything at all

Not Happy

Difficult to use, app is all about marketing, not intuitive at all

Expensive

After purchasing the scanner, you still need to pay 20/month to use the function

Toyota Tundra

Took my Tundra to 2 different dealerships after my key fobs lock/unlock/panic/ remote start buttons stopped functioning after a settings change in the vehicle’s customization menu. Both dealerships said they never heard of it. After some research I found some other owners had the same issue and bought this scan tool to fix it. Took me 5 minutes including reading the instructions and my truck was back to normal including the remote start!

EVO scanner “bricked”

Told via app to update to latest version to carry on using. Scanner no longer works!! Will not connect to app anymore. Support absolutely useless.

UPDATE. 05 Aug 2026
After receiving a response (and after spending the last week back and forth with “support”) I received the instructions on how to “reset” the EVO module. A further 2 hours and no further on, will not connect and carry out firmware reset/update. As said, the module is bricked following previous update!! Send me a return envelope and you can have it back to fix at your leisure, it’s of no use to me.

Привет пиндосы, Вы зачем спрятали приложение для России?

Major increases in subscription pricing.

Even though their own website FAQ says you can purchase a 1-month subscription for $14.99, there is no longer any option to buy that term. Instead, you must pay for an expensive full year, or an in-app single month of use priced at $29.99 — a 100% price increase. The software is nearly useless without a subscription. Other apps offer comparable functionality at much less cost. Too bad that Carista let greed ruin their excellent product.

New version breaking compatibility

I have been using the app to reset the tire pressure sensors of my 2017 Rav4 with the OBD Link MX+ OBD scanner. Unfortunately a Carista app update broke the functionality and Carista support refuses to address the issue, with their resolution being using a different device or downgrading firmware which is a no go for me as I use the device with other vehicles requiring latest firmware. Breaking functionality on devices to favor their own is despicable.
