Is it a common problem that hitting snooze on the alarm is /too hard/? I find myself paying for apps that make hitting the snooze button complicated. Captchas.

Is it a common problem that hitting snooze on the alarm is /too hard/? I find myself paying for apps that make hitting the snooze button complicated. Captchas. Math. You name it. Is there any combination of sensors that gives the smartphone an idea if I'm properly awake? Not talking about light sleep vs dreaming here. More the "will he get out of bed" kind.
