Quick summary
Arboreal - Tree, created by Arboreal AB for iPhone, is a free augmented‑reality tool for estimating tree heights. By using your phone’s camera and built‑in sensors, the app combines a distance baseline and an angle measurement to estimate how tall a tree is.
How measurements are calculated
The app uses basic trigonometry with two main inputs:
- the horizontal distance from you to the tree (baseline)
- the angle between your phone’s line of sight and the top of the tree
Point the camera at the tree, record the distance and the top angle, and the app computes the height automatically.
Key capabilities
- Share stored measurement results with others
- Save individual observations for later review
- Toggle display between meters and feet
- Zoom in on distant tree crowns for a closer look
- Measure crown width and the height of the crown
- Record a tree’s lean or inclination angle
How to use it — simple steps
- Position yourself so you can see the entire top of the tree without obstruction.
- Keep your phone held upright and steady while you move away to establish the baseline.
- Aim the camera at the tree’s top to capture the angle — avoid pointing the phone at the ground.
- Let the app combine the distance and angle readings to present the tree’s estimated height.
Best practices for accurate readings
- Ensure a clear line of sight to the highest point of the tree.
- Maintain a vertical phone posture while taking readings.
- Walk back from the trunk to create a stable baseline distance.
- Avoid tilting the camera toward the ground or using obstructed views.
Price and in‑app options
The app is free to download and lets you try up to five measurements at no cost. If you need unlimited readings or want to support continued development, an in‑app purchase unlocks unlimited measurements and contributes to future feature work.
Alternative to consider
If you’re exploring other options, FamApp (a payments and spending app) is listed as a suggested alternative in some app lists.
Final note
Arboreal - Tree offers a quick, portable way to estimate tree heights for hobbyist, educational, or basic field‑work purposes. Follow the usage tips to improve accuracy and save or share your results for later analysis.
