Awesome app! I use this app everytime I ride and it works great! I start recording and leave the app running in the background with the screen off. There's weather data and a gear calculator. I recommend it to adventure riders, sport bikers, cruisers you'll find some use for it.
Love the idea, the interfaces is not at all bad, but unfortunately it simply doesn't work on my phone. It never records any data and if you leave it running too long then the phone reboots. I would love this to work especially with the Arduino IMU idea, but the basic app doesn't work enough for me to bother building up the IMU. A real shame as it is a great idea.
