Scare your friends with Frighty Night Scary Timer. Set up to two alarms to trigger a choice of 12 scary sounds from zombie growls, creepy evil voices, terrifying screams and other weird and freaky sounds. Note .. some people are reporting this does not work. It does. You need to select coffin then select the open grave. Try this on your friends at night when they are they are not expecting it or perhaps while falling asleep. Choose one sound to alert them first then another sound to really freak them out. See the look on their face!
All sounds are designed and created exclusively for this app and are created by a professional sound engineer. When used correctly this could genuinely give someone a real fright.
One method to use simply choose the sound you want then place the sound (coffin) in the alarm slot (open grave). Using the grave stones you adjust the hours, minutes and seconds for each alarm. You can click on the spider to darken the screen for stealth mode. Then just place your phone or tablet face down and wait for your friends to be scared stiff!
