Mag Assistant for Android

By DanGP $1.99

Developer's Description

The Mag Assistant is a tool that may be used to detect magnetic fields and warn of high magnetic radiation*. It is useful for people with pacemakers and others who are sensitive to magnetic fields, as they can detect the radiation near them and be warned in advance if they are near areas or objects with high magnetic fields. It can also be used to detect other metals as well.

* High magnetic radiation is around 1mT (millitesla) or 10G (gauss), as cited by Boston Scientific (SOURCE: http://bit.ly/1So3BU0)

Mag Assistant is the most complete magnetic field detector on Android, complete with background services, event logging, graphs and multiple adjustable threshold warnings, ideal for engineers or those with pacemakers.

NOTE: The effectiveness of the magnetic field sensor is dependent on the sensor of the device used and can vary on different devices.


Simplistic monochrome design

High magnetic field warnings with notifications

Runs in the background, can still measure magnetic fields whilst minimised

Event log indicating when and where the magnetic field thresholds have been breached

Adjustable threshold warnings

Values measurable in millitesla or Gauss units

Graphs for measuring the magnetic flux over time

No ads, popups or intrusive events

Low resource usage

Only 1 permission required (for getting the current location)

Ideal for measuring magnetic flux density for science lessons

Please note that this app relies on the Android device having a magnetic sensor. You can check whether your device will be compatible by installing the Mag Sensor Advisor beforehand, downloadable for free: https://play.google.com/store/apps/details?id=com.magsensoradvisor

Comments and feedback will be greatly appreciated as it will help to further improve the app.
