While the app worked well to start with, the more I used it the more I noticed that it would sometimes only show me the pie-chart at the top of the screen and wouldn't let me access the more detailed information further down the page. All very straightforward, but then Google Fit doesn't have very many features at the moment, so it will be interesting to see how the usability changes as Google develops the app. There is one main screen where you can see all your data and a settings button in the corner to add your details and change your goal. While you do have to sign in with your Google account and activate location reporting (that's not going to be popular), you don't have to enter loads more complicated details to start and much of the information is optional.

It has a well-designed, clean, and clear user interface with graphs that are easy to understand. If there is a way to do this, it is well hidden, which completely defeats the point. I tested it with FitBit, Runkeeper, and Endomondo and none of them worked. While Google says that it allows you to connect third-party apps and devices (including Android Wear devices), I had no idea how to do this. There is also no way to track the calories you have burned, nor anywhere to enter information about your diet, so quite why you have to add your weight when you first launch the app is unclear. Unfortunately the pedometer - which is designed to automatically track your every move via the phone's sensors - isn't very accurate and sometimes won't record activity or will only record parts of itĪt the moment, there are only three activity types you can record – walking, running and biking, or you can mark it as ‘other’. So, say you lend your phone to a friend and they go for a run with it, that will forever be logged as your exercise.

However, while you can edit your activity, it doesn't seem to be possible to delete any of it. While Google Fit automatically tracks your activity, you can add it manually as well.
