Google announced a new platform called Fit on Tuesday that aims to put all the fitness and health data from your apps and devices in one place. It's a shot across the bow of Apple, which provides iOS users with a similar service in HealthKit. The idea is that if you use one app to track your runs, another to watch calories and a third when you bike or lift, you shouldn't have to go through all three to see your progress.
The app itself will track walking, running, and biking durations. Google's blog post mentions Strava, Withings, Runtastic, Runkeeper and Noom Coach, but if you're using something brand new or not as well established, you might want to check if it's supported by Google Fit.
Reviews of the app and comments on the announcement are already asking for help with connecting this service or the other — and Fitbit, one of the most popular options out there, may very well snub Google's app the way it did Apple's HealthKit.
Google Fit may be a bit barebones, but it's a handsome interface, works with the new Android smartwatches, and will likely only get better and more widely compatible. You'll need an Android device running 4.0 or higher to use it.
