Nice idea but it has a lot of points to work on. * you have to keep your screen on all the time with the app in the foreground, so almost impossible to use your phone for work and needs to charge all the time. * need to play games and watch adds to be able to get the subscription costs out of it (or literally drive all day, I already drive a lot and couldn't get the subscription costs out of it) * Without subscription (even with the NFC, it's so slow it's not worth the hassle it asks of you.
