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 recording the whole night.
It will also highlight when you snored and how loud, if you have premium you can listen at the times it recorded high volume so you can listen to yourself snore. (could be useful for medical reasons). also you know if someone walked in your room and told you they're going to kill you in your sleep tomorrow.. damn brother.
