Tesla Bot is a unique application designed to function as a "Geiger counter for magnetic fields" on iPhone devices. It generates synthesized Geiger counter-style clicks based on the intensity of the magnetic field, using the device's built-in compass/magnetometer for measurements. The sound synthesis closely mimics authentic Geiger counter clicks, modeled after the CDV-700, providing users with an immersive experience.

It's important to note that Tesla Bot may not work on current iPod Touch models lacking a compass (magnetometer). The app can detect magnetic fields within a range ofmicrotesla, offering various operating modes like tracking changes in magnetic vector, compass direction indication with pronounced clicks at the north, and customizable individual vector axis detection.
