After releasing [Smart Ruler] for length measurement, I had to develop an angle measurement. It has 3 protrator modes.
※ Introduction video
Ⅰ. Touch mode
Ⅱ. Plumb mode
Ⅲ. Camera mode
In plumb and camera mode, touch anywhere on the screen. "Holding..." text will blink.
※ Menu & Settings
※ Orientation sensor ??
Most protractor apps are using only an acceleration sensor. But this way has restrictions. When the slop is bigger than 60 degrees, the measurement can be inaccurate.
This app provides the best solution. Orientation sensor!! It calculates tilt using both magnetic sensor and acceleration sensor. The result becomes more reliable. I recommend that you turn on this option.
Several custom ROM and non-magnetic devices cannot activate orientation sensor. Please check your 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
※ What's new

- v1.0 : Smart Protractor released (Sep, 2010)
