RadMobile vs magnetoboy

RadMobile app displays real-time radiation measurement information from gamma-ray and neutron detectors of directly connected RSI devices through Wi-Fi network, notifies immediately upon anomalous radiation activity and high radiation level detected providing the ability to user to send email reports with attached measurement data formatted according to IEEE N42 standard. FEATURES: - Wireless connection to RSI device - Continuous radiation level monitoring - Fast notifying upon radiation detected providing Nuclide ID and dose rate - Gamma and neutron count rate display, dose rate display - Uninterrupted operation for immediate response on detected radiation - Graph indicating detected radiation level in a range of received measurement samples - Map view with current RSI device location - Alarm sound upon radiation detected - RSI Device information and status screen

Use your device's magnetometer, and read out the magnetic field (micro teslas). You can observe and examine the magnetic fields around you.  You will find that certain materials change the magnetic field. Such as Iron, magnets, nails, speakers, some metals, electronics, the earth, and more. This may be used to find things, that are ferromagnetic. Change the feedback level to get a vibration when some strong magnetic field is nearby. Observe the graph to visualize the fields around you. Can be used in construction: by attaching a magnet to something behind a wall and use the app to locate the target. The magnetometer, is usually used in navigation to detect the magnetic fields of the earth. The phone must not be in mute for the sound to work.
