After releasing [Smart Ruler] for length measurement, I had to develop an app for angle measurement. This app has 3 protrator modes below (touch, plumb, camera).
※ Introduction video
Ⅰ. Touch mode
Ⅱ. Plumb mode
Ⅲ. Camera mode
In plumb and camera mode, touch anywhere on the screen. The red "Holding..." text will blink.
※ Menu & Settings
※ Orientation sensor ??
Most protractor apps are using only an acceleration sensor. But this way has restriction. When the slop is bigger than 60 degrees, the result can be inaccurate.
I tried to find a good solution with an orientation sensor!! It calculates tilt using both magnetic sensor and acceleration sensor. The result becomes more reliable. I recommend that you turn on the option [Orientation sensor] if possible.
Several custom ROM and devices without a compass sensor cannot activate orientation sensor. Please check the specifications and turn off this option.
1) 6 tools (ruler, level, thread) are integrated
2) More Tilt units
3) More languages supported
4) No ads
