Sveaskog
Sweden's largest forest owner compared Arboreal Forest with manual measurements on more than 300 trees. The systematic diameter error was less than 1 mm and the area error about 1%.

Revolutionary mobile apps for precise tree measurements in the forest. Collect digital data with ease.
Measure trees with the phone you already carry
Arboreal makes apps that turn your phone into a measuring tool for the forest. With the camera's AR and the phone's LiDAR sensor you measure tree height, diameter, crown, basal area and volume – without caliper, measuring tape or hypsometer.
Our apps have been downloaded more than 500,000 times and are used in almost 100 countries by forest companies, forest owners, consultants, arborists and researchers.

Tested by independent researchers
Forests, 2023
The first peer-reviewed comparison of Arboreal Forest, Katam and Trestima. Arboreal Forest got the highest score (15.5 points, against 12 and 6).

Tree Scanner gave almost the same basal area as a professional personal laser scanner in 50 plots, at 11 seconds per tree instead of 51.
Read moreDigital tape measure, 2026
Our test of Arboreal Tree against a tape measure: 203 measurements on 8 devices, a mean deviation of 6.8 mm and R² = 0.998.
Read moreFrequently asked questions
›How accurate is measuring trees with a phone?
With LiDAR, very accurate. In Sveaskog's evaluation of Arboreal Forest the systematic diameter error was less than 1 mm, and in our own test of the digital tape measure in Arboreal Tree the mean deviation from a tape measure was 6.8 mm over 203 measurements. Peer-reviewed studies in Forests (2023) and Ecological Informatics (2025) reached the same conclusion.
›Do I need a phone with LiDAR?
No, but it helps. LiDAR makes diameter and distance measurements fast and very accurate, and is found in iPhone Pro and iPad Pro models. Without LiDAR, Arboreal Tree measures height with the AR camera and diameter with the digital tape measure, and Arboreal Forest measures diameter with the camera. Tree Scanner needs LiDAR.
›Which phones do the apps work on?
Arboreal Forest and Tree Scanner are available for iPhone and iPad. Arboreal Tree is available for both iOS and Android.
›What do the apps cost?
All apps can be tried for free. Arboreal Forest is a subscription, paid per week or per month. Arboreal Tree is either a one-time purchase or a Basic or Premium subscription.
›Can I get my data out of the apps?
Yes. You can export measurements, share plot data with colleagues and fetch your data over our REST API, for example into GIS or your own forest systems.
›Who is behind Arboreal?
Arboreal is a self-funded Swedish company in Umeå. It was founded in 2018 and started at the business incubator Uminova Innovation.

It Was Never Just Tree Height — The Advanced Measurements in Arboreal Tree for iOS
Johan Ekenstedt
5 Aug 2026
When we launched, this app was called Arboreal Tree Height. We dropped that last word a while ago — here's everything else that's in there. A new tutorial for the iOS version walks through diameter, circumference, crown shape, crown width and height, and how to measure a tree you can't even get close to. Under three minutes.

Optical fingerprinting of logs — finally ready for deployment
Johan Ekenstedt
25 Jun 2026
For two decades, recognising a log from the features it already carries — no tag, no paint, no barcode — was a research problem. It's now mature enough to deploy. Here's how the field got here, and what it took to turn it into a working service.

Measuring Thick Trees Just Got Easy — the New Digital Tape Measure in Arboreal Tree
Johan Ekenstedt
23 Jun 2026
A new digital tape measure in Arboreal Tree wraps around the trunk and gives you diameter, circumference, and cross-sectional area at once — built for the thickest trees, and it works even on phones without LiDAR.
