RunKeeper This GPS-based running app is like having a track coach in your pocket. It’ll record your splits, map your run, track your elevation gain and send all the data to your online RunKeeper account so you can view your progress over time. It even gives you no-nonsense audio cues through your headphones when you hit mileage benchmarks or let your pace slow too much. Hamstring massage not included. Free.
MyFitnessPal Food diaries suck. Counting calories is a time drain. Nothing derails a diet faster than denial. Face the caloric facts with MyFitnessPal, an app that tracks what you’re eating and calculates what you need to do (or stop doing) to meet your goals. Best of all, this app takes the guesswork out of nutrition—it’s loaded with restaurant data, so you’ll know just how much fat is in that Chipotle chicken burrito, whether you want to or not. Free.
Zombies, Run! You can hear them in your headphones: the lumbering, blood-thirsty groans of zombies closing in with an eye on your brain.

Each workout becomes part of the story, with details revealed as you walk, jog or run, collecting medicine and supplies at certain mileage counts. Just don’t stop moving! $7.99
