Google Fit was first announced at the Google I/O conference in June 2014 and is a comprehensive app which brings together all of your fitness tracking data into one accessible place.
In this way, it easy to see the app as a direct competitor to Apple's recently released HealthKit - and it makes a lot of sense for both Google and Apple to be releasing these kinds of products as people become more interested in not only fitness apps but also extended activity trackers.
Thankfully for those who are just looking to get a little more active, Google Fit tracks everything you do and starts with simple goals like aiming at 1 hour of activity a day. It will track your steps and give you notifications for the amount of time you've been up and moving. You can set new goals and see them tracked on a graph, getting an over view of your activity level as time goes on.
Google Fit will also integrate with third party apps and even hardware, including Android Wear smartwatches. Companies like Nike, LG, Withings, Motorola and Runtastic are said to be working with Google on the app, but they're not all integrated yet.
Google Fit is a simple and accessible way to track your fitness and is available for free from the app store now.
