Universal Detector turns your iPhone or iPod touch into a Hi-Tech environmental scanner capable of finding rare Geological features and detecting embarrassing mental and physiological traits in people.

No, well, actually it's a novelty app designed to play tricks on your friends and family. Almost the same thing!

How to use it

Tell your friends what you are scanning for, 'gullible people' for instance, then sweep your phone around the room a bit.

Ping

When the Detector detects a 'gullible person' it alerts you and displays what it has detected on the screen.

What really happens: If you tilt the phone left or right a fraction the iPhone displays a message.

Customizable

You can choose a couple of messages, maybe, one naughty and one nice.

Yup, the Universal Detector doesn't just detect 'gullible people', you can customize it to detect virtually anything. That's why it's called a Universal Detector.

Recall

You can save your detector setting to recall them when right the situation arises.
