## What is Fluxmeter?

Measure the invisible electromagnetic fields that surround us. This utility uses your device's built in magnetometer to scan for 50/60hz alternating current waves, emanating from power lines and unshielded devices that use alternating current, such as desk fans, space heaters, or toasters. 

Fluxmeter uses a proprietary algorithm to "zero" out the Earth's magnetic field, allowing measurement of the local area magnetic flux only.

## Key features

- Detects electromagnetic fields
- Uses device magnetometer
- Scans for 50/60hz AC waves
- Measures local magnetic flux
- Proprietary zeroing algorithm
