Well, if you wanna get your daily activities traced so that you could get a fit and healthy body, SLife has got best accuracy around the store. In terms of functionality as well as simplicity , SLife is the best. From my personal experience, I found that SLife traces my daily activities (Biking, Running, Walking, and Driving).
