Ever wanted a alarm that won't shut up unless you act something big on it? This is the one. You can only shut the alarm up by answering the easy but annoying (when you just wakeup!) Math calculation.
Also, ever tried some alarm app and notice the significant power drain overnight? That's why this app is for you, it dramatically reduce the power drained while you sleep.
*Remind: Please don't change the phone's volume after you have set the alarm, otherwise the alarm will not be LOUD enough (if you decreased the volume manually). This implementation prevents power drained overnight.
