Hey guys. What's the best fitness app for wp8? I'm currently still on wp8 and using the paid version of runtastic. It's OK, fairly basic and temperamental. I've researched something called micoach, which looks promising. I was planning on buying the runtastic heart monitor but don't want to spend ?50 on that, then upgrade to wp8 in January and find runtastic to be inferior to other options available. Is micoach better than runtastic. Or is there even better ones than both of them?
