MagSense

A magnetometer utility app designed by magicians for magicians.
From the creators of Email Wizard (an amazing app acquired by the legendary David Copperfield).
If your magic routines include magnets, this app is for you. Simply put, MagSense is a utility app that will tell you when a magnet is within the range of the magnetometer. Unlike other magnetometer apps currently available, this app is designed to be stealth, so the spectator will not know that an app is in use. You can set the app to vibrate when a magnet is in range, use a small visual cue in the corner of the screen which can be set to black (so the device appears to be asleep) or a screenshot of your choosing.
Simple to use, takes just minutes to set up. MagSense should be considered a utility app, and is not a magic trick by itself. You should use this app to enhance your current performance. This app is not for beginner magicians/mentalist. You should already know the basics to incorporate this into your performance.
Includes three suggested routines written by Columbian mentalist Mauricio Jaramillo.
A magnet is required for routines (not included). This app is for entertainment purposes only and does not provide any real mind reading abilities.
