It is a compass that shows 16 directions in an easy-to-understand manner.

It can also be used as a compass to check the direction of eating Ehomaki during Setsubun.

Please read if you feel that the compass is not working properly.

Compass app works with magnetic sensor (gyro sensor).
Not all smartphones and tablets have a magnetic sensor, so please check if your device has a magnetic sensor.

Also, if you are using a case with a magnet, or if there are objects that generate magnetism such as batteries, other smartphones, mobile batteries, or outlets nearby, it may not work properly.
Please use it in a state where there is no object that generates magnetism.
If you feel that the orientation is off, please calibrate the magnetic sensor.
The magnetic sensor will be adjusted by turning the smartphone to draw the figure of eight, so please try it.

Some models do not have a gyro sensor/magnetic sensor.
The compass does not work on that model, so please check with your dealer.
