It is a simple incline meter (clinometer).
I measure an incline and display it like the signboard which there is a sharp slope in.
[characteristic]
・The drawing card indication that it is easy to watch
・It is operation-free and is easy
・Change of a sensor mode and the GPS mode
・Change of percentage notation and the frequency notation
[sensor mode]
・I calculate an incline from the angle of the terminal using the accelerometer of the terminal, a geomagnetism meter.
・It is more correct than GPS.
・Because 0 points of adjustment is possible, the relative incline is demanded.
* Because I use an accelerometer, the measurement becomes incorrect at the time of acceleration, slowdown with the moving bodies such as a car or the train.
[GPS mode]
・I calculate an incline from a high change using the GPS receiver of the terminal.
・Because I do not depend on the angle of the terminal, it is not necessary to mind way of holding.
* The precision of the altimeter of the GPS is not so generally good.
Therefore I cannot guarantee the accurate result. Please spend it for reference degree.
