Flying Ruler is a tape measure, ruler, protractor and a goniometer (angle-measurer). It is four devices in one app, providing you with the quickest way to measure a distance or an angle.
The Flying Ruler app allows you to measure in the most original way: by just moving your device from one point to another.

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. You can not only measure an object but also the distance between two walls.
*** Only on iOS ***

"I was impressed with Flying Ruler’s accuracy. It works quickly and effectively", "It’s the perfect addition to anyone’s app collection" -- 148apps 4.5 / 5 (MUST HAVE)
"I literally said “wow!” when I first used this app and I think it’s a truly impressive marvel of mobile technology", "The Flying Ruler Rules" -- AppPicker (Cons: there is nothing negative to say about this app)
You can choose either inches or centimeters.
The app has different modes so you can choose which mode is better and easier to use on each occasion. You can measure with the body of the device in one mode or with a virtual ruler in another. 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.
The app also allows you to save a measurement by taking a photograph of the measurement and mark the place that was measured.
Don’t forget to show your friends and colleagues how the app works – believe us, they will be impressed.
ACCURACY OF MEASUREMENT:
We took 100 consecutive measurements and got these results:
On iPhone 6 Plus:
∙ Mean squared error - 0.49%
∙ Maximum inaccuracy - 1.2%
∙ Number of measurements where inaccuracy was within 1% - 93
On iPhone 4:
∙ Mean squared error - 1.02%
∙ Maximum inaccuracy - 3.0%
∙ Number of measurements where inaccuracy was within 1% - 65, within 2% - 96
The accuracy of measurements depends on the device, however the error rarely exceeds 3%. You can always increase accuracy by making a series of measurements. If you make a series of measurements, the degree of error is usually 1% or less.
- the user interface for switching modes of measurement is changed
- VoiceOver support is improved
- new inertial spec calibration for increased accuracy (when necessary)
- improved performance on the iPhone 6S and 6S Plus
- optimized for iOS 9
- other minor alterations and improvements
