Yes, all those things. I've had the Flex, which is the fairly basic model, and currently have the Charge 2 (I had the Charge HR but they have a habit of falling apart). It tracks sleep and heart rate and various activities, calories burned, etc.
Basically it's just a bracelet/watch type thing and everything else is synced up with your smartphone or computer.
