I Tested Carista App + Adapters | Owner’s review
Last Updated on April 11, 2026 by Juraj
I tested Carista on my Toyota Corolla and a few VAG cars to see how good the app is for real diagnostics and coding. I focused mainly on the app itself because most people buy Carista for the software, not the adapter.

Comparison to Other Tools
vs OBDeleven – OBDeleven wins on VAG coding depth and adaptations. Carista is simpler but shallower. If you own VAG, OBDeleven gives more control.
vs ELM327 adapters – Most ELM327 chips work with Carista. Best budget move: cheap ELM327 + 1-month sub instead of buying the EVO.
vs ecu Coding scanners (Kingbolen K7, Mucar VO7, Thinkcar) – Tablets win on service menus, live data, and bi-directional tests. Carista doesn’t compete here.
vs Carly – Carly is overpriced, unstable, and cluttered. Carista is cheaper and cleaner. Not a close fight.

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.
