Yet another gem out of Google I/O is Google Fit. This is a common platform for developers to build their health-related apps, and, more specifically, tie in wearable monitoring hardware. Using this API, apps will be able to swap and pull in data to build comprehensive images of your fitness. This is all done with explicit user permission, and you can always nuke any biometric data you don't want lingering around these apps.
Nike Fuel and Noom are just some of the partners demoed at Google I/O, but Adidas, Withings, and Runkeeper are just a few of the other big names that are already on board. There will be a paltform preview made available to devs in a few weeks.
What do you guys think? Could you use a better means of allowing your various wearables to talk to one another? Be sure to relive the event through our Google I/O liveblog!
