The Seth On Survival Monstrometer. It’s a dangerous world we live in, teeming with supernatural threats and monsters in disguise, so how do you know who to trust? And how will you survive?

Let the Seth On Survival Monstrometer be your guide. Use it to scan and interrogate old friends and new acquaintances to determine if they are really supernatural beings in disguise.

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.

The Monstrometer has been updated regularly with new information and results and now you can even watch Seth's Zombie Month survival videos right from within the app.

On the SOS website you'll find Monstometer tips to help ensure your survival.

(Also some cheats to trick your friends!)
