Zombies are a subject in itself. Though they are not scientifically proven, many people believe in them and other supernatural beings. Some even operate the ghost hunting as a hobby. They use different tools and sensors to prove an existence.
With the Zombie Detector, you can also feel like the zombiehunter. At least in the eyes of others, but only you know that it is a simulation and not a real emp-detector (electromagnetic pulse).
If you have tricked your friends with the Zombie radar, then write a comment. Even what you told them exactly, for example that you also can detect ghost and monsters with your smartphone. No less interesting is where you have encountered spirits.
Give also the other reviews compliance, from experience many funny comments will be posted.
Always hold in your mind that this App expressly is a simulation, just for entertainment! A real zombie tracker for mobile phones is technically impossible. In addition, the existence of spirits is not confirmed.
