I really miss Wakemate. Despite the wristbands being not terribly well-made (I went through three of them), it's the only system that did exactly what I needed it to do, which is to wake me up within a 20-minute window at a point where bodily movement is higher than usual. Worked like a charm for me. There are apps that do this but they require you to sleep with your phone next to you on the bed, and I can't imagine that they work as well as a wristband...
