Carista App

Carista is an Android app that lets users check their vehicle for problems.

Carista is an Android app that lets you check your vehicle for problems, as well as clear any existing fault codes. You can also customize your car to your liking! Carista is compatible with standard (i.e. inexpensive) ELM327 Bluetooth adapters that plug into your vehicle's diagnostic OBD2 port. Carista can check your vehicle's health and report any faults stored its computers. Unlike other apps, Carista gives you access to advanced manufacturer-specific diagnostics, including computers like ABS, airbag, navigation, etc. You can also clear any fault codes and reset your check engine light, airbag light, ABS light, traction control light, etc. Carista lets you change the way your car behaves: say you want your headlights to come on automatically when you start the engine; or you want the doors to lock when you start moving; or you want to change the type of beep that the reverse parking sensors make. Yes, Carista can do that (if your vehicle supports it, of course). Carista's overheat alarm (a paid feature, 99 cents) allows you to monitor your engine's temperature and react early if it starts to overheat. Carista can run in the background and notify you with an alarm sound right when the engine temperature starts to reach dangerous levels.
