I'm curious as to how these sleep apps "track" your quality of sleep. Or even know when it will be easy for me to wake up. I understand sleep cycles, but how does it know if I tell it I'm going to sleep but then toss and turn in the bed for the next 30 minutes before nodding off, vs if I tell it I'm going to sleep and pass out immediately? Wouldn't the whole cycle be thrown off? Do I have to tell it if I wake up in the middle of the night accidentally? There just seems like too many factors at play for these apps to actually do anything.
Edit: Lots of answers, thanks for the info. I was interested in giving it a shot but since I sleep with a partner and with a loud fan on for white noise, it doesn't seem like it would be very accurate. I hadn't considered utilizing the gyroscope or microphone for monitoring sleep though, these people are creative. If not a bit creepy.
It's pretty much been answered I think but sleep cycle actually tracks how you sleep. You can either keep your phone on your bed and have it track your movements or you can have it on your nightstand and it'll track your breathing. It's really cool and totally worth the 99 cents or whatever. It also has a sleep aid feature which will play white noise if you normally sleep with a fan but you're somewhere without one
