Stop watch, mile counter, route map, personal trainer—these days there’s an app for every runner’s needs. For your next workout, turn your GPS-enabled phone into a trustworthy running coach with one of these popular apps.
With an easy-to-use interface, Run Keeper tracks your pace, distance, time, route and calories burned by using the GPS built into your phone. Set audio cues to receive motivation at time- or distance-based intervals, or program a target pace and get audio updates as you run. After your workout, upload the data to the website to keep a training log. Free or $10 for the Pro version, Runkeeper.com
Whether you’re doing fartleks, intervals or sprints, the Ultra Timer can function as your go-to stopwatch. Choose from a library of alarm sounds or record your own, and pick screen colors to distinguish between timers. The Timer Group allows you to program a full workout with different timers and alarm sounds, so you can go through a warm-up, intervals and cool-down without ever looking at your phone. $2
