The team behind Runkeeper seems to be always busy working on the app. It receives regular enhancements and only a month after its Google Fit integration, the 'RunKeeper - GPS Track Run Walk' has added support for another device that runs Android Wear. The new Sony SmartWatch 3 SWR50 is now supported by the app. This means you can use the smartwatch and run even without your phone. The latter's GPS will track you as you run and data will be synced to your smartphone when you get back.
