I'm a long-time aCar user (donated waaaaay back when), but have stopped using it with my new car, simply because I've lost data too many times. I'd inquired about testing when you acquired aCar, but that was some time ago.
Would love to be on the beta program for aCar, I have GasCubby Pro for my IOS device but the S7 is my main phone so would like like to test out an app for Android.
