I am using SKI TRACKS – Will use to record Slope % and Speed this year.
Second year – using this app on a low end, eMOTO, 4.4 kitkat.
If you have it works on Android, iPhone, BlackBerry
NOW Push to talk Apps – Like walkie talkie.Enhanced
Could use to keep in touch on slope race info etc. Chat to team in other states.
Choices : Use wifi / 2G,3G,4G 2G is nice.
