The Best Free Running Apps for iPhone

Slide 1 of 12

“It's hard to find a smartphone-toting runner who hasn't at least heard of RunKeeper, let alone used it,” says Time. With more than 25 million users RunKeeper is among the most popular of all the free running apps out there. Whether you’re a veteran runner or just jumping on board the exercise bandwagon, whatever fitness tracking tools you need, Runkeeper has them. And the creators are constantly adding updates. Two new 5S features not commonly found in your average app include Pocket Detection, which works like a pedometer to track your daily movement, and a stride rate chart feature that lets users see how their stride rates change when running or walking.
