TomTom and Nike are back in each other's arms. The former's Runner and Multi-Sport GPS Watches, including those that come with heart-rate monitor bands, are now compatible with the Nike+ app. These two companies have collaborated back in 2011, when Nike came out with a sports watch that's loaded with GPS developed alongside TomTom. This time, the masters of navigation are giving you a way to auto-upload calories burned, run pace and time, among other types of data to the running app (and earn NikeFuel in the process, of course). Even if you don't use Nike+ for either iPhone or Android, though, you have other apps to choose from, as the company's watches also support TomTom MySports, RunKeeper, MapMyFitness, Jawbone, Endomondo and Strava. All you have to do now is find the motivation to do some actual running.
