An incredibly effective wake-up alarm clock, the Sleep If U Can phone app practically dares you to try and stay awake with its annoying system.
It has several conventional alarm types including waking up to music, vibrations and also a shake mode that turns off the alarm when the user physically shakes the phone. However, none of these stack up to the most annoying alarm aspect. When the alarm goes off, the user can only stop it once they get out of bed and take a photo of a preset image, the bathroom sink is a good choice since it’s generally the next stop after waking up.
Forcing the user up is what makes this wake-up alarm clock app simultaneously obnoxious and effective.
