I use a couple of apps in order to track my sleep. I have sleep apnea, so I like to check how much noise I am making in a night. I use SnoreLab for that. When I don't want to track snoring solely, I use Sleep Cycle, which tracks the agitation of your sleep, and uses that to wake you up. The tracking info is quite good as you can see the amount of rem sleep and where in the night that happened. It is also good to perceive trends through time in terms of sleep quality.
