Version 2.0 adds a new Yearly Growth Curve, improved Good/Average/Poor year scoring, and replaces Planting Year with Cutting Year for easier reporting. Also includes visual polish, icon refinement, and stability improvements.
MoreTreeRings analyzes a photo of a tree's cross-section and counts the visible growth rings to estimate its age. Wider rings generally indicate favorable growing years, while narrower rings suggest harsher conditions.
Beyond estimating age, TreeRings offers insights into the favorability of each growing year, reflecting past climate conditions. It can also help identify patterns in local climate over time when comparing multiple trees.
The app provides approximations and fascinating insights, but it's important to note that these are estimations. For precise scientific research, professional dendrochronological methods may be required.
