Measure just about anything with your iDevice with Flying Ruler.

What is it about?

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

Flying Ruler Pro

For those who...

  • It’s great for projects around your home.

Not for those who...

  • Accuracy varies by iDevice. Older iDevices like iPhone 4 will have an error rate that’s much higher. Also, if you have a case around your iDevice, you’ll have to measure it to help improve accuracy.

Why we love it

If you don’t have a ruler or protractor readily available, download Flying Ruler today. It works like magic.

App Store Description

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

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.

Measurements take place extremely quickly and at the same time they are quite accurate. We are constantly improving our computational algorithm for more than 7 years - it is difficult to find an application (that calculates distance by moving) with a longer history!

COMPETITIVE ADVANTAGES OF FLYING RULER:

• measurements can be carried out in any light and on any, even monophonic surface
• Flying Ruler was designed so that visually impaired people could use it using VoiceOver, for other technologies this is often impossible
• many measurement modes for all cases (length, height, flat and dihedral angles, there is even a virtual ruler), you can not only measure an object but also the distance between two walls
• Flying Ruler will never tell that you moved the device incorrectly: the computational algorithm compensates for any inaccuracies during movement
• the maximum distance is 999 ft for the imperial system and 99 m for the metric system
• when measuring, you can avoid obstacles and therefore you can measure anything
• Flying Ruler is suitable for measuring not only large, but also very small distances with the accuracy of a standard ruler
• 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 8:

• Mean squared error - 0.16%
• Maximum inaccuracy - 0.5%

On iPhone X:

• Mean squared error - 0.19%
• Maximum inaccuracy - 0.6%

On iPhone 5:

• Mean squared error - 0.29%
• Maximum inaccuracy - 1.3%

The accuracy of measurements depends on the device, however the error rarely exceeds 2%. You can always increase accuracy by making a series of measurements. If you make a series of measurements, the degree of error is usually 0.5% or less.

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).
