Moasure uses the same technology found in rocket guidance systems –

yes, it really is rocket science!


This includes accelerometers, which measure g-force, and gyroscopes, which measure rotation.

They take 100 measurements per second as the smartphone is carried from A to B.

Complex software algorithms process these measurements, to calculate precisely how far the smartphone has been moved and rotated. It literally measures its own movement.


Moasure is limited by the accuracy of the smartphone sensors. Typically this means measurements have a tolerance of +/- 1-2%.

There are a number of things you can do to increase the accuracy: 

Time, not distance, affects the accuracy of the measurement. The quicker it’s taken, the more accurate it will be. Move your smartphone as quickly as you practically can, without dropping it!

The app supports the swift taking of the average of a few measurements to increase the accuracy. Taking two or three measurements will typically decrease the tolerance to +/- 0.5-1%. For further information, see our Accuracy of Measurement page.

We’re committed to continuous improvement of Moasure, and expect to announce further exciting developments about accuracy improvements soon.

Moasure is available in English, French, German, Spanish, Italian, Portuguese and Polish. We’re currently working on making it available in other languages. Tweet us @MoasureOfficial to let us know which language you’d like us to develop next.


Location services

To make sure your measurements are as accurate as possible, you’ll be asked to enable location services as you launch the app for the first time.

Measurements are affected by the precise location at which they are taken. Gravity, measured by the accelerometers within Moasure, alters with altitude and latitude (you weigh about 0.5% more at the poles than on the equator) . But rest assured, we promise Moasure will never share your location data.
