I'm a Gyroscope user and really enjoy it. It combines tracking from different sources well, making it easier to understand your day, and take action based on that.

hm, seems like the bet is to get people that are not as scientifically well-versed to get into exercise through nice data visualization and fun shareable images of their exercise. probably has a higher likelihood of getting people to exercise instead of saying "cathespin B is good for you and here's why" people seem to be sharing their stuff
