I have DashPi for iOS and it works but I didn't see it on that list. It does seem like it hits the shift light a little sooner than it should, not sure if I can adjust that or not, but other than that it works fine on PC2.
All apps for pCARS1 are still supported. Just make sure that the UDP feed is set for "Project CARS 1". The "Project CARS 2" UDP stream is apparently not yet enabled.
All i know is P.Cars Dash needs android 4 or higher no idea about the rest of the apps. I was running it on a galaxy tab 2 and 3 with no problems there about 5-3 years old i think.
