Here's a really fun looking Android app to give your kids a scare this Halloween. The Amazon AppStore free app of the day is called, "Ghost Radar," and it can turn your Android smartphone into a genuine supernatural event detector! (Of course it's for entertainment purposes only.) The app utilizes several of the sensors in your phone in cool and creepy ways to help you hunt down the spooks in your area. It gets mostly positive reviews, and is definitely worth a look for those who may want to get some Halloween usage out of their Androids.
