I use this app all the time as I snowboard 2-4 times per week. Its great to record each day, and see statistics. However, I havent a clue what the "subscription" is for - I thought it would allow me to edit if there was an accidental run entry (i.e., driving and having it say your highest speed was 80mph). It doesnt really do the trail and lift thing very well at all. It needs another page with statistics and totals and records, etc. To find my highest speed of the season, I have to go through each of my 30 days. Its good for recording speeds and miles and such, dont get me wrong, but go donate your money to a good cause instead of this scam!
