Identify a tree from its bark, leaf, needles or whole form.
Tree Identifier is an iPhone app that reads a photograph of a tree and returns the likely species, the family it belongs to, where it grows, the visible details that gave it away, and the lookalikes worth ruling out. Every result carries a confidence level.
Most tree apps need a leaf. In winter, on a bare trunk, or with a plank on a workbench, that is exactly what is missing — so this one reads bark too.
