What’s the point?

I downloaded the app to find out battery health, got the paid version to run the tests and it just crashes. I would like to have a refund. Apple store should pay attention to crap like this.

Hi Edgar,
Please email us at support@PriusApp.com and we will help figuring out the issue, most likely OBD2 adapter related.

Prius Reverse Beep

Just got my first Prius and immediately learned how incredibly annoying driving in reverse can be with a constant beep. Not a great way to start any day when you first get in the car. Quick Google search brought me to this app and the creator’s VERY detailed site. Purchased one of the Bluetooth OBD2 tools suggested on Priusapp[dot]com for iPhone (NEXAS NexLink). With a couple minutes of setup I was able to accomplish the goal of getting reverse to beep ONCE. Very grateful for this app and its creator! 2018 Prius Two and iPhone 13 Pro, if that helps anyone looking into this!

Email support response.

I had a question about compatibly and literally within 2 minutes of sending the email I had an answer to my question.

ODB device on order so I haven’t tried the app yet. But so far I’m impressed with the app support.
