Update: using recommended adaptor I am blown away. Additional to upfront information the report is a whole new level. I am surprised this feature isn't paid or at least in part. When it works this app is incredibly generous with what it gives for free. I don't get much information, but I have a message saying bad obd. I can monitor battery voltage. I read the FAQ I believe the obd adaptor I have is good, but I will get the recommended and try again. Dr Prius worked fine.

Fantastic app. Running on my Rav4 Hybrid 2019 Aus. Be sure to check the compatibility OBD2 adaptor section on web sight. Would appreciate HV fan control like Dr. Prius app provides.

Works fine with my Toyota Prius. It helps me to keep an eye on all the HSD functions. Interface is good and easy to understand.

Hybrid Assistant is not compatible with newer Toyota hybrids, and is no longer being supported by its developers.
★☆☆☆☆Zackary Kimberlin· Mar 19, 2026
Used to love this app. Now it doesn't stay open and disconnects. Battery optimizations turned off, just disconnects.
★☆☆☆☆Eulises Gonzalez· Jun 24, 2024
App can't detect my car 2024 Toyota Corolla cross hybrid and is constantly losing connection or sometimes just close itself. I have bought 3 different obd 2 scanners, and all of them have worked with Dr Prius app very well. But no luck with Hybrid Assistant.

Didn't work with VLinkr FS and 2021 Toyota Corolla Hybrid (GAC Toyota Levin model year 2021)
