Use The Seth On Survival Monstrometer to scan and interrogate old friends and new acquaintances to determine if they are really supernatural beings in disguise and then learn how to deal with them. You can even scan yourself and link with others who share your supernatural condition. The Monstrometer uses a biometric finger scan and a battery of psychometric questions to determine the probability that your subject could actually be a zombie, vampire, werewolf, leprechaun or other dangerous supernatural creature. Recommended for anyone who has ever wondered, if I ask for her number will she just sink her pretty teeth into my carotid artery and suck out all my blood? And why is my friend acting so weird? The Monstrometer has been updated regularly with new information and results and now you can even watch survival videos with werewolves, zombies and leprechauns right from within the app with even more new videos coming soon. On the SOS website you'll find Monstometer tips to help ensure your survival. (Also some cheats to trick your friends!) Developed by supernatural survivalist Seth Greening, host of web series Seth On Survival and the upcoming Monstrometer Report and the online home of supernatural survival http://www.sethonsurvival.com Knowledge is power. Less power than a functioning particle cannon, true, but still. Don’t be caught unprepared! A fun social game and important survival tool.
