Bitterlich relascope is an Android app developed by Deskis OÜ that helps users estimate the basal area of forest stands. Unlike traditional relascopes, the app doesn't require you to hold your phone at a specific distance from your eye. The app has assisting lines on the screen that help you count the trees. On the screen, you can see the result in m2/ha. Trees that are thicker than the difference between the lines should be counted as +1, and trees that are exactly the lines between should read +0.5.

The app is available in English and Estonian, making it accessible to a wider audience. Bitterlich relascope is a calibrated and ready-to-use program that can provide accurate results for forestry management. Overall, this app is a useful tool for those in the forestry industry who need to estimate basal area quickly and easily.
