Getting out of bed in the morning is one of the curses of modern life - and it's not made easier by the temptation of the snooze button.
Seemingly in an effort to help raise us from slumber each day, +Microsoft has unveiled a new alarm app that forces you to prove you're awake before it stops.
So, for example, it might ask you to snap a selfie or play a particular game before it finally shuts up.
The app, called Mimicker Alarm, may ask you to take a picture of something green - or repeat a tongue twister over and over.
If you don't complete the task, the alarm starts up again.
