Flying Ruler Pro for Android

11 things about Flying Ruler Pro

1. The Flying Ruler app allows you to measure in the most original way: by just moving your device from one point to another.

2. Flying Ruler is a tape measure, ruler, protractor and a goniometer (angle-measurer).

3. You can measure with the body of the device in one mode or with a virtual ruler in another.

4. The accuracy of measurements depends on the device, however the error rarely exceeds 1.5%. You can always increase accuracy by making a series of measurements.

5. Flying Ruler is suitable for measuring not only large, but also very small distances with the accuracy of a standard ruler.

6. Angles can be measured with the app to an accuracy of one degree so the app can easily take the place of a protractor or a goniometer (angle measurer).

7. The secret of the program is that it is based on the principles of the inertial navigational system (INS): the position of the device is determined with the help of the accelerometer and the gyroscope.

8. You use the same methods to measure angles as the app allows you to measure angles both on a surface area and between surfaces through space.

9. It is four devices in one app, providing you with the quickest way to measure a distance or an angle.

10. The maximum distance is only limited by the value of the indicator which consists of 999 ft for the imperial system and 99 m for the metric system.

11. The app also allows you to save a measurement by taking a photograph of the measurement and mark the place that was measured.
