Very slow and lagging – Map My Fitness by Under Armour Review

I want to love this app, and I mostly do. However 4 out of 5 times, it freezes and crashes. I want to utilize the features like goal setting and the social part of challenge with friends, but the app doesn’t even let me get to that because it’s frozen. I have the latest iPhone, so I’m sure it’s not my device. Hopefully this gets fixed.
