Two things Ive noticed so far is that the app shows the "todays goal" always shows the wrong date and the main screen. When you click on it the correct one is there but you cant do anything to fix this. Secondly, the app doesnt load the sleep data at all. This is particularly annoying because the sleep data is sold as a feature to the Fuse and you cant read the data except for on the app. Im considering returning the Fuse for something with a better corresponding app.
