Now you could measure the height of a tree with high accuracy. The app uses AR technology in your phone to measure the distance from the tree and the angle to the top of the tree to get an estimate of its height.
The best tool is the one that´s always with you, your phone.
You could also measure buildings, poles, towers and bridges.
- Feet/ Meter
- Save measurements
- Measure the inclination of a tree
- Measure the crown width
- Measure the height of the crown
- Share your measurements
- Measure the diameter (requires Lidar)
In order to get the best results, hold the camera in an upright position when you walk away from the tree. Don´t point the camera to the ground. Try to stand some distance from the tree and have a good view of the top of the tree.
You could test five measurements . You could buy unlimited measurements and help us to add more features.
1. Go close to the trunk of a tree (2-3 feet) and move the camera in order for the device to locate the tree. Aim at the tree and press mark.
2. Walk away from the tree about the same length as the tree height
3. Aim at the base of the tree. You could zoom in the picture if it is har to se the base. Press the mark-button.
4. Aim at the top of the tree and press the mark-button.
5. Give the tree a name and save.
If you have a phone with Lidar you could now measure trees with larger diameters.
Ratings and Reviews
Great concept- I wish it also had tree diameter
I think it works well, you definitely want to walk far away from the tree to get better results.
I will know how accurate it is when the actual tree survey is done.
But it worked for my needs, not perfect but definitely better than just guessing.
Please add a DBH measurement option. Thanks.
3 different heights 4 same tree
I gave the app 2 instead of 1 star bc operator error is factored in. I downloaded the app bc of the good reviews and went outside to calculate the height of a tree I want to cut down. I opened the app and couldn’t find any instructions but it directed me to point at the tree trunk, did that and without further instructions I pointed at the bottom of the tree and hit the picture button and then pointed at the top (I was about 25’ away from the tree). It said I was too close so I walked away up a slight hill. The dot was off to the side of the trunk but I thought somehow the app still knew what to do and I tried to get it as close to the trunk as possible. I shot the top of the tree and got a measurement of 31’. To be sure, I tried again and it measured about 48’ and a third time it measured 25’. Waste of time and dangerous if you were to base a cut off this incredibly unreliable data. My suggestion would be to get a better app developer. Thorough instructions should be offered on the first page. I shouldn’t have to tell you that. I wasted my free measurements on just trying to figure it out. I need this type of measurement device but wouldn’t use these guys because of the time I wasted measuring (and writing this dumb review)
Developer Response ,
Sorry to hear about your experience.
The problem is probably caused by either a hardware problem on your device or some strange way to use the app.
To check if it is a hardware problem, test apples own measurement app "Measure". If it doesn't work well, it is a hardware problem.
Please take a look at the Tutorial video here: https://youtu.be/trAZPfany8Y
It shows how to use the app. Good luck with your measurement. / Johan
Accurate and Easy to Use
I had to measure a huge Eastern White Pine and started with my Suunto clinometer and a 100 foot tape and took 3 different readings from different locations. Then I tried the app and carefully followed the easy directions and took another three readings. All of these readings were within 1 percent of each other and within 1 percent of my clinometer reading. The height was 140.2 feet using three readings from each of the two methods. I am a retired forester and familiar with tree measurements.
A couple of tips. You need to be able to see the very top of the tree and the base of the tree. You need to go out a hundred feet. You can zoom on your phone to get the crosshairs on the top and base of the tree. Don’t drink coffee before trying to take precise measurements or if you do put the phone on a tripod, but only for high accuracy. Newer phones have Lidar and that technology is getting better all the time.
Great app and this New Hampshire forester won’t be hauling around a 100 foot loggers tape anymore.
