MyTOYOTA is an iPhone app developed by TOYOTA MOTOR CORPORATION that is available for free. It is designed for Toyota and Lexus car owners who have a common ID. It provides two ways to use it; either by connecting your vehicle's T-Connect/G-BOOK or by connecting with a Toyota dealer's maintenance service.

If you own a Toyota or Lexus and have a common ID, MyTOYOTA allows you to check your car's status and driving data from the app. The app's main features include security, health check, car finder, my car log, and drive diagnosis. However, the availability of these features depends on the auto's model, grade, and equipment.
