Arboreal - Tree is a free iPhone app developed by Arboreal AB that allows users to measure the height of trees with high accuracy using AR technology. With this app, you can simply point your phone's camera at a tree, measure the distance from the tree, and the angle to the top of the tree to get an estimate of its height.

The app offers a range of features to enhance your measurement experience. You can switch between feet and meters, save your measurements for future reference, and even zoom in for a closer look. Additionally, Arboreal - Tree allows you to measure the inclination of a tree, the crown width, and the height of the crown. You can also share your measurements with others.

To get the best results, the app recommends holding your phone's camera in an upright position as you walk away from the tree. It's important not to point the camera at the ground and to have a clear view of the top of the tree. The app also provides step-by-step instructions on how to use the app effectively, ensuring accurate measurements.

While the app allows users to test five measurements for free, there is an option to purchase unlimited measurements and support the development of additional features. With Arboreal - Tree, you can now conveniently measure tree heights and contribute to the world of tree analysis and research.
