Tree Ringer

An app to estimate the number of rings on a tree slice.
Available on the Google Play Store

Tree Ringer

Touch around the center of the rings for the start position, then at the edge for the end position. The app will count all the rings along this line.


When an image is messy, it is a good idea to take and average of the ring counts at a few positions, try to select the cleanest regions. See the figure below.
