View your distance, step and heart rate* information at the click of a button. This app reads your recorded steps and distance and presents a simple combined view - also includes "feels like" data. The interface is designed to use on the run with one hand, so big buttons and simple swipe gestures are all that's needed Swipe left or right for additional screens. Swipe up to view the high-contrast screen ideal for use in the sun. Swipe up again to go back to the normal funky red view. First-of-a-kind "feels like" feature! Our team of coffee-drinking developers sat down one day and developed proprietary fuzzy logic to make this app even better. We take altitude into consideration along with speed and distance walked or ran to create a "feels like" distance. We call this logic: fuzzy logic because it sounded good at the time. Even so, it means, if you walked all the way uphill for 5km, the feels-like value might be 8km for example, so you get rewarded for the extra effort of walking up a hill. Our custom algorithms are leading the world in this intuitive technology! Many health apps only view per workout, but what if you do more than one walk or run per day? This app collects all information from your phone or apple watch to give you a single view. Also allows weekly, monthly, 3, 6 and 9-month views along with one and two-year views. *Heart rate feature requires apple watch
