So i tried the app that fly linked to last night.... that is the most comprehensive alarm system ive ever seen in my life.
It can record any sleep talking you do, or snoring, and even has a trigger to break you out of a snoring cycle
It records your sleep cycles with the accelerometer
It has anywhere from 1 to 10 minute gradual increase alarms, with gentle sounds (seagulls, beaches, oceans, etc). I've found that a gradually increasing gentle sound wakes me up much better than a harsh one
It has "lullabies where it can play soft noise of your choice before you sleep and fade it out
It monitors your sleeping in the morning, and wakes you within -x% of your set alarm time when you are already in a lighter sleep state.
All that said, the sleep mapping feature to determine what phase of sleep you're in is nothing short of amazing. It produces a graph last night that looked just like the sleep pattern graphs in every classical academic test.
@MapleySyrup the 90 minutes thing should be null with that, as it actively knows what part of your sleep cycle you're in. Ill post my graph from last night up when i get home, it should show exactly how long my sleep cycles are.
@fly, thanks dude... this is awesome so far.
