Google's Fit app, as its name suggests, helps people monitor their exercise programs. It tracks such activities as walking, cycling, by utilizing sensors built into Android phones.

As Google puts it, "as long as you're taking your handset with you they'll be able to track your progress." Users can set their fitness goals and then monitor their progress through the phone, the web, tablet, and Android Wear devices.

The layout has the same look and feel as Lollipop, Android's latest operating system, which will appear on selected smartphones on November 3.

Google Fit can be used with such similar apps as Runtastic, Runkeeper, and Strava. It can also integrate with accessories like heart rate monitors and Android Wear smartwatches. Graphs and charts show a person's health statistics. They can also show how a person's stats like heart rate, calorie intake, and weight change over time. The data is displayed through a ring akin to that used by Apple Watch or the Human exercise app.

Users can also manually enter information about workouts that haven't been tracked, or one's height and weight by plugging into their Google accounts. The app is spare, but provides a central location for all of one's health-related information.

As Google said in a blog post, "No need to check one app to see your weight and another to review a run - with Google Fit, that data will all be surfaced in one, simple place."
