A free app for Android, by Aleksandr Radionov.

distance is an application for measuring distances. You can use it to measure the distance between two points.

The app uses the parallax method. The method is accurate to a certain extent, but it is also necessary to take into account the characteristics of the camera and the object.

The range of the application is from 1 meter (yard) to 10 km (miles) or more. The accuracy is good, but the accuracy depends on the size of the object and the quality of the image.

It is necessary to calibrate the application before use.
