Dr. Prius is a powerful app designed for professional Toyota/Lexus hybrid repair shops and vehicle owners to monitor and test the remaining life of your Toyota/Lexus HV battery. If you encounter any issues, please reach out to us at [email protected]. We're here to help you resolve problems quickly, and leaving a one-star review isn't the best way to communicate your concerns.

With Dr. Prius, your mobile device transforms into professional diagnostic equipment that typically costs thousands of dollars. Trusted by over 439 professional repair shops worldwide, this app allows you to effortlessly assess the health of your High Voltage battery. By simply touching your smartphone screen, you can access all relevant battery information, identify problems, and even print a certificate to validate the battery's health.

To use Dr. Prius, you'll need an ELM327 Bluetooth OBD interface to communicate with your hybrid vehicle. Note that most cheap clone ELM327 devices won't work due to their inability to switch between ECUs. For more details on compatible adapters, visit PriusApp.com/obd.html or email us with any questions. It's generally not recommended to use WiFi OBD2 adapters because of potential internet disruptions during connection.

1. Real-time battery monitoring with intuitive charts and data points.
