About this app

A magnetic field sensor (also known as magnetometer) reports the ambient magnetic field, as measured along the three sensor axes.
The measurement is reported in the x, y, and z fields and all values are in micro-Tesla (uT).

Wake lock: Device will not sleep during operation.

Ratings and reviews

Excellent app. Clean UI. Would be cool to have different types of meter designs to choose from & also to locate where the magnetometer on the phone is but seeing as it's free the different designs/themes could be a purchase option? Its great to see an app with no ads 😁 Thank you! 🙂

Does exactly what it says, works great on my Pixel 9a, has a nice set of config options, and doesn't have any ads! Hard to believe an app like this exists in 2025, but hats off to the developer for their service to the community!

Great little app! I love the vibration festure when it detects a magnetic field nearby. Super handy.
