Google Fit is a health-tracking platform developed by Google and announced at the Google I/O conference on June 25, 2014. Google Fit is a single set of APIs that blends data from multiple apps and devices. Confirmed partners include Nike, HTC, LG, Withings, Motorola, Noom, Runtastic, RunKeeper and Polar. Users will be able to choose who their fitness data is shared with and also delete this information at any time.
Google Fit was announced shortly after the release of Apple's IOS8 HealthKit and can be considered a direct competitor.
