Compass 3D

Compass 3D is a dynamic Chrome extension that visually represents magnetic fields using a stunning 3D needle display. It enhances user interaction by briefly vibrating your device when the phone aligns perfectly with the magnetic field. Additionally, it intelligently brightens the screen in the presence of strong magnets to provide clear visual feedback.

Ideal for enthusiasts and professionals alike, Compass 3D helps you intuitively understand Earth's magnetic environment. Note that in the U.S. and Europe, the magnetic field points into the ground, which is perfectly normal. For further details and source code, visit the project page.
