    I see only few people talk about Car Scanner Pro app on here for Gen 2, so i am opening this thread to show how cool this app is for Gen 3 too.
    I got it yesterday and so far, it's amazing. If you have an experience with it, you can also share.

    PROS:
    -It has alot of sensor reading for Prius
    -Customisable Dashboard
    -Custom Action PID
    -Coding

    CONS: Electric Pump RPM reading isn't functional for me at time of writing.

    I can display upto 30 sensors and action on the app dashboard, which includes Engine, Battery, Distance since codes clear, warms up e.t.c
    Also create a custom action to clear DTC on the go without leaving the Dashboard screen. (04 is the custom command for ELM327 DTC code clearing)

    CONS: It is not capable of communicating with all the ECUs in a Gen 3 Prius, but it comes very close. You just need to know its limitations. https://priuschat.com/index.php?posts/3564647

    It is a very nice app for most people to use. It is better than 95% of the scanner apps that are available. I like it very much.

    I'm curious how it compares with OBD Fusion, which also communicates to CarPlay?

    I do not use the OBD Fusion app. Maybe someone else can answer your question.
