I’ve used the Sleep Cycle Smart Alarm Clock app for 50 nights now, so why not look at some data from it? The two things I track are the length of my sleeps and the quality ratings (which are, as far as I can tell, based partly off of how long a sleep is and how much time is spent in deep sleep according to the app).
As far as time goes, I’ve slept an average of 4 hours and 35 minutes over the past 50 nights, with the shortest night being 3 hours and 13 minutes and the longest night being 7 hours and 43 minutes.
For quality, my average over the past 50 nights has been 45.37%, with a minimum of 21% and a maximum of 79%.
Yeah, I don’t sleep very much.
