Teslameter 11 - Metal Detector!

Teslameter 11 takes advantage of the built in magnetometer in your iPhone/iPad, allows you to monitor the strength of magnetic field all around. There are a range of real-life applications for this useful item, such as: metal detector, AC magnetic fields, or finding low-magnetic places for sleeping (especially for babies) and of course, why not fun as well?Features:- Display the raw 3 axes x, y and z magnetometer values and a nice analog meter to display the magnitude - 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
