I have been a long time user of Sleep As Android. It has a lot of features to track sleep quality including respiration tracking, %time in deep sleep, snore tracker etc. You also don't need to put your phone on the bed with you to track your patterns with a feature called 'sonar'. I've never used the feature, but apparently it uses your mic to pick up ultrasonic sounds.
If you use it for your alarm it can also wake you up when you are in a lighter sleep phase as opposed to disrupting you while you're in a deep sleep. There are "Pro" features you need to pay for, but the basic functionality is free.
