Solving complex math equations often turn out to be a hair wringing experience even when fully alert.

To utilize the program's basic function, users who find it hard to wake can take and save photos on their smartphone before they go to bed of random objects and barcodes around the house.
Then, when the alarm goes off in the morning, users must get up and take a photo of the same object or barcode, the New York Daily News reported.
Until they do, the alarm will continue to sound, creating an ever-so-annoying, but cleverly functional, way to get you on your way.
Under one setting users must get up from bed and take a photo of a household item suggested by the phone to get the alarm to shut off.
And for those who have an even harder time getting out from under the covers, there is a unique "evil" setting, where users must complete math equations that are difficult to solve, even when wide awake.

And for each one, a sharp tone will continue to sound until the task has been completed.
