Carista 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. No more paying dealers an hour's rate for 2min worth of work!
Carista can check your vehicle's health and report any faults stored its computers. You can also clear any fault codes and reset your "check engine" light, as well as check if you're ready for emissions testing. Carista is compatible with all manufacturers and models, as long as they are OBD2-compatible (all 1996+ cars in the US, all 2001/2004 petrol/diesel cars in the EU, etc.) Unlike other apps, however, Carista also gives you access to advanced manufacturer-specific diagnostics*, including computers like ABS, airbag, navigation, etc. and gives you the ability to reset your airbag light, ABS light, traction control light, etc. for supported models.
* Manufacturer-specific diagnostics are a paid feature, available on a selection of 2005 and newer models from Volkswagen, Audi, Seat, Skoda (VAG), Toyota, Lexus, Scion. OBD2 diagnostics are free.
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). Customizations are a paid feature, available on a selection of 2005 and newer models from Audi, Lexus, Scion, Seat, Skoda, Toyota and VW. For Lexus, these are called Lexus Personalized Settings (LPS).
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. Yes, most cars have a temperature gauge on the dashboard, but how often do you look at it? Carista can run in the background and notify you with an alarm sound right when the engine temperature starts to reach dangerous levels.
You need an ELM327 Bluetooth dongle/adapter in order to use Carista. We do not sell these; they are available from Amazon, eBay and a number of other merchants. See http://www.caristaapp.com/hardware/
No live data or dashboard
Please don't download this app if you're looking for display of real-time data. That's not the purpose of Carista, so please don't rate us negatively for lacking such functionality. Just use Torque for that.
Note: Carista is an OBD scan tool and diagnostics app with added functionality for the consumer. There is no separate Pro version, but there is a paid "Pro Package" within the free app that you can purchase using Google Play In-App Billing. The idea of this app is to provide a simple and efficient way to configure your car to your liking, diagnose your "check engine" or "service engine soon" light, and prevent your engine from overheating. Nothing more, nothing less. Carista is compatible with all vehicles that comply with OBD2 (sometimes misspelled ODB), including Toyota, Lexus, Scion, Honda, Acura, Nissan, Infiniti, Mazda, Mitsubishi, Subaru, Suzuki, BMW, Mercedes, VW, Audi, Seat, Skoda, Porsche, Opel, Peugeot, Citroen, Renault, Fiat, Alfa Romeo, Lancia, Mini, Lotus, Jaguar, Rover, Tesla, Chevrolet, Ford, Chrysler, Dodge, Jeep, Buick, Cadillac, Pontiac, GMC, Lincoln, Saab, Volvo, Hyundai, Kia. We have advanced functionality available in our Pro Package for a selection of models from VW, Audi, Seat and Skoda (VAG group) and Toyota, Lexus and Scion.
