Google Fit

The search giant is offering a number of incentives for developers looking to add Google's fitness tracking capabilities to their existing and apps.

With a quick glance at the smartphone or watch, users will be able to see how close they are to their goal and stay motivated.

The grand prize winners and the runner ups will be receiving devices from Google's challenge partners to help with their ongoing fitness app development.

Developers will be able to use a set of cross-platform APIs to make their apps and wearables sing along, pouring in data into a single pool of data.

The company also unveiled a fancier, Titanium Edition device (available for $299.99) along with a new line of fashionable leather accessory straps.

The service itself will aggregate all data fitness apps are producing, organize that data, and when user demands - show it all in a nice-lookin' format.

The software adds support for manual entry 100+ new activities, and experimental step detection when an Android Wear watch is disconnected from the phone.

The search giant released an open source sample called Games in Motion to demonstrate how developers can make fun games using Google Fit and Android Wear.

The application allows users to track their activities either automatically or manually input the exercise type, duration and distance.

The service will apparently collect inputs from other apps and devices like fitness bands and heart monitors, while offering APIs developers can tune into.
