All the while, the startup has quietly been building a “correlation engine”, because simply aggregating fitness and health data from a few devices wasn’t enough — RunKeeper users had been clamoring for a way to make sense of all the data integration from third parties.
This is great news. I’ve used RunKeeper to track my runs for a long time and love it. It’s an iPhone app that used the built in GPS to track your distance and pace while letting you choose a playlist to keep you pumped. Definitely recommended.
