About
Polus Magnes is a magnetic and acoustic signal visualizer for everyday observation.
The app helps you notice changes in the magnetic field near everyday objects, electronics, cables, adapters and other nearby sources. It also includes a sound meter screen for relative ambient noise activity. Readings are shown as clean pulse-style graphs so changes are easier to see at a glance.

Polus Magnes is useful for simple observation, learning, everyday experiments and visual comparison between different objects or places. For example, you can save a session near a power adapter, speaker, desk or another object, add a note and photo, then compare it with another saved record later.
Polus Magnes is not a professional measuring instrument. Results may vary depending on device model, sensor condition, distance from the source, nearby objects, phone case, environment and other factors. The app is for general observation, education and casual experimentation—not for precise diagnostics or as a substitute for certified professional equipment.
