B etween apple and android devices, there are over 25,000 apps that are available for download. This is one of the fastest growing app categories and in my opinion one of the more useful ones as well (although of course there is a time and place for posting photos of food, playing angry birds or seeing what your face looks like when combined with your boyfriends). These apps have many different uses and the one(s) you download should take into consideration your goals and your fitness level.
