To begin with there is G-Sports, a very handy stopwatch combined with GPS tracker which collects data on distance run, speed and pace as well as displaying your route on a map alongside graphs relating your speed. Sessions are stored in the workout calendar and the app even speaks to you to tell you how you’re doing! Purchase price for G-Sports is £1.99.
SmartRunner works in a similar way to G-Sports, but rather than just retaining all of the information about speed, distance, calories and so forth on your phone, with an account at www.smartrunner.com you can save and publish this information online. Again using GPS to collate the data, SmartRunner also features integration with social networking services like Twitter and Facebook. This top app is available for free!
If you’re planning on just keeping time yourself, Stopwatch Sport is a more simplistic Windows Phone 7 stopwatch app, featuring different timers to use as a lap timer, countdown or as a standard stopwatch. This app can be downloaded for 79p.
Finally, if your fitness is based purely on how far you run or walk, Step Counter is a very clever application which records each step you take throughout a day. Also including a stopwatch, Step Counter makes use of your phone’s movement sensors in order to record just how many steps you take in a given day. Step Counter is 79p on the Zune Marketplace.
