"Magnetscape" is a new measurement app that observe invisible magnetic fields by using a built-in iPhone magnetic sensor.

There are various magnetic fields in our surroundings. For example, the magnetic field fluctuates even with a large motor, a compressor, or a metal nearby. Earth's magnetic field exists even in places where there is nothing, and we are affected by that magnetic filed.

"Magnetscape" can monitor the surrounding magnetic field in real time, it can be used for various purposes in real life. For example, it can be used for investigation of static magnetic field, search for low electromagnetic field at alternating magnetic field (electromagnetic field), metal detection and more.

"Magnetscape" has three kinds of measurement modes for magnetic field observation, please use it according to your purpose.

- Scope
Perform a graphic display that shows the magnitude and direction of the magnetic field.
In Scope, the magnetic flux density of the magnetic field is expressed by the size and color of the graphic circle.
The display position of the graphic circle, but will move to match the polarity of the magnetic source, the polarity is attracted towards the N-pole if it is the same direction as the geomagnetic field, polarity is reversed away if it is the opposite (S-pole). If there is no metal or magnetic field nearby, it will be shifted in the direction of the geomagnetism (N-pole).

- Time
Trace the RAW data from the magnetic sensor and its corrected data. It is a time displacement graph of each axis value (Bx / By / Bz) and composite magnetic flux density (Bcomp) in three-dimensional space. You can scroll up to 180 seconds.

Perform frequency analysis on changing magnetic field. It displays the result of FFT analysis of composite magnetic flux density.
Horizontal axis: Frequency 1 - 16 Hz (0.5 Hz)
Vertical axis: dB (ratio to default standard value 45 μT),  Reference value can be set in units of 45 ± 15 μT / 1 μT.

- Graphical display of magnetic field observation by magnetic sensor (Scope)
- Time displacement graph display of magnetic field observation (Time)
- FFT analysis (FFT)
- Magnetic field observation
 X axis: intensity (Bx) of the magnetic field of (the right direction toward the screen)
 Y axis: intensity (By) of the magnetic field of (upward toward the screen)
 Z axis: magnetic field strength (Bz) in the of (vertical upward direction of the screen)
 Composite magnetic flux density: The magnetic field strength (Bcomp) that takes all three components of the x axis, the y axis, and the z axis into consideration
 Sampling frequency: 32 Hz
 Unit of observation value: uT
- Measurement time: 3 minutes
- Alert function: A warning message will be displayed if the composite magnetic flux density exceeds 300 μT.
- Alert sound function. (Sound Off/On)
- Peak hold function on FFT mode.
- Angle display function in Scope mode (Angle)
- Clock display function in Scope mode.

- The display value of this application is the RAW output data from the magnetic sensor itself. It does not make any processing such as filtering processing inside the application.
- Since the magnetic sensor is a delicate device, the internal reference value of the magnetic sensor may be disturbed by being exposed to extremely strong magnets and magnetic fields for a long time.
- If the reference value of the magnetic sensor goes wrong, once you stop the application and leave it for a while, the magnetic sensor is readjusted automatically. If the magnetic sensor is still unstable, please try the electronic compass calibration and its reset procedure.

Please visit our iOS App Support page for more information on this app.

A good first attempt

The sampling frequency does not capitalize on the latest phone hardware and should be selectable, higher than just 32 hz

The peak frequency should be numerically displayed, not just a bar graph. Since the value is easily calculated, it should be displayed.

I wasted my money because I have an app with a configurable trace where I can literally count waves and compute frequency. Was hoping the FFT function would work better and actually record a value for the computed frequency.

Pleased with the app/ Icon disappeared

I enjoy this app. For some reason, even though the App Store still shows my purchase made for it, and other apps in the Comfortable Life Package of apps, I cannot get the app icon to show on my home screen. I go to the App Store and open it from there, but never get the app icon added back to the screen. Thanks
