The Carista app is used for diagnosing car problems and customizing the car. While it lacks many important features for diagnosing, it is pretty good for coding and unlocking new features of your car.

Carista – Quick Overview
Carista is not one versatile device for car diagnosing; it is more like a coding supplement. You can use it for coding the car, and you will need another device to diagnose problems.
How I review products
On my website Iamcarhacker.com, I am committed to providing genuine and thorough reviews. I believe in the importance of firsthand experience, so I personally test every OBD2 scanner I review. Before I share my insights and opinions, I make sure to purchase and use each product, ensuring that my reviews are based on real-world usage and experience. Check the full review policy.
What is Carista?
The Carista adapter is a Bluetooth OBDII scan tool that connects to your smartphone/tablet. The strength of this device is in diagnosing the fault codes because it can scan all of the car’s control units.
Another reason to buy is the option to unlock or customize features of your car, like the turn signals, remote keys, locking options, etc. You won’t get many options for the live data and service functions. I recommend this app for occasional 1-month payment, just do your customizations and cancel the subscription.
Which adapters work for Carista?
Carista has own 2 adapters, a classic Carista Adapter and a new Carista EVO. Other than that, it also works with other ELM327 adapters like Veepeak.

How much does the Carista cost?
I am recommending Carista only for a 1-month because it lacks many diagnostic features like live data graphs and full live data, nor does it have complete engine live data. The Car Scanner app is better for diagnosing, and Carista is good only for coding and customization. If you unlock the hidden feature, it will be stored in your car, so you can cancel the subscription and keep your customizations.
| 1-month | $10 |
| 3-months | $20 |
| 12-months | $50 |

I test OBD-II scanners and make DIY Engine diagnostics guides to help you solve your car problems without having to depend on the mechanic. A lot of them will try to scam you or are just no help at all. About Juraj Lukacko
I ordered Carista’s OBD II adapter (arriving today), but I would like to know if I can use it and the Carista app to program a new key on my 2011 Toyota RAV4. Do you know if it supports this? Someone in a RAV 4 forum said to use it for this, but Carista support wasn’t able ti tell me if it had that capability. Thanks!
Hi scanners like this can never program a new key, they only sometimes can code new keyfob (so you can lock/unlock but cant use it to start). However I never saw any key coding option in Carista app so most likely the answer is NO.
