The newest app from the makers of Email 'n Walk!

Detect nearby metal objects with your device! Amaze your friends by showing the magic of your electronic compass.

This sucker actually works! Hold it near a metal object and watch the needles show you the magnetic fields in action!

Note: You need an iPhone 3Gs in order for this to work because we use the internal compass to detect magnetic fields.

Also: If it gets stuck beeping, move your device around in a figure-8 or just shake it around a bit until it stops.
