A lot of people have asked for an Android version of our app Arboreal – Height of tree. We have listened and now released it on Google play We are recommending Android 9 or later and use a phone that support AR. Here is a list of supported phones that support AR.
The app uses the sensors and cameras on the Phone together with AR-technology. There is different sensors and cameras and they have been calibrated in different ways. It makes the result differs between different device models. We have tested the result on some phones that we got available and made a movie about the result. We aim to calibrate Samsung S7, S8, S9 and S10 to get a better result. It is not possible for us to test all different models and we need your help.
Please share your result with us. Tell us what phone model, how many measurements you have done and what you have measured (known height or other method to measure). We will add your experience in the list below. You could make a comment below or send an email to firstname.lastname@example.org
