What's New in TreeRings

3.0

October 19, 2026

TreeRings 3.0 introduces a major upgrade to ring analysis: - Improved detection of closely spaced and irregular rings. - Better handling of challenging photos, with clearer uncertainty messages. - Clear gaps where yearly measurements cannot be estimated reliably. Yearly scores compare relative ring growth within the tree. Calendar-year labels are approximate.

Waste of money

I tried it with very old spruce trees and it told me it’s 7 years old

Doesn’t work

It came back and told me my tree is 10 years old. I can physically count the rings to at least 120…

Boo

2 stars too generous. Simple photo of 80 year old tree cross cut. App says 3 years old. Good by. I want my dollar back.

Needs to allow photo library

Not sure how it works, you can only analyze by taking a picture through the app.
