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.
