There are so many iPhone apps for runners, it’s hard to decide which one to use. Should you go for a familiar brand like Nike, or a specialist like Runkeeper?

Ultimately, all running apps do pretty much the same thing: They use GPS to track how far and how fast you run. But when you take a closer look, their features and prices vary considerably. So I’ve done the leg work for you, to help you find the right running app faster.

Apple Watch has been on our wrists for just five months and yet it is already having an amazing impact on many people’s lives.

We want to find out how Cult of Mac readers are using Cupertino’s fitness tech to get in shape, so we’re inviting everyone to share their inspiring stories. Plus, we’ve set up a new Cult of Mac club on Strava so you can connect with other readers who are into fitness.

If you compare the Apple Watch to dedicated fitness tracking devices, it comes up short, and the forthcoming watchOS 2 will do little to address these limitations. Instead, with this update Apple is focusing on helping improve third-party fitness apps.

That’s because Apple sees its wearable as the main component of a fitness platform, with the Activity app as hub. While the built-in Workout app is mostly for beginners, third-party apps will provide the missing features for hardcore users.

Using a running app to log your workouts is a great way to track your progress and stay motivated. But have you considered who actually owns the workout data you are logging?

If you ever decide to switch apps, you might be in for a surprise. While some services, like Strava, make it easy to transfer your data, with others it can be difficult or even impossible.
