Sleep (was: Phones and apps forced on you)

I use one such app that tracks my sleep. One feature it has is the alarm
clock. Instead of a fixed time to wake me up, it checks during half an
hour if it is the correct phase of my sleep to wake me up.

  If I don't have any appointments on a given day, I pin down
  a time to wrap up my sleep based on how long I want to sleep.
  Then, when I come to, I check if it's past that cutoff time
  for sleeping and get up if that's the case. If I've got stuff
  on my plate, I set an alarm, but I often find myself stirring
  just before it's set to go off.
