- Display the graphical history of magnitude (size, strength) of the magnetic field

- Support multiple units: tesla and gauss

- Record and export the data to email for further analysis

- Define your own threshold alert with audible alarm when it encounters a field (metal, speakers, etc.)

- Sensitivity customizable

- Start or stop the teslameter at any time

- Enable/disable auto-lock screen
