About this app

Measure angles between two points on the geo sphere with the camera and augmented reality.

Device orientation is obtained with the accelerometer and gyroscope, or with the accelerometer and magnetic field sensor. Each method has advantages and disadvantages and can be selected with the gyro or magnet buttons (only if your device has the necessary sensors detected).

A sphere with azimuth and angle of elevation lines is shown overlaying the camera view.
Two positions can be set putting markers onto the view. The angle required to rotate from one to the other is shown, as is the difference in azimuth and angle of elevation between the two points.

For Indication Only. Note that in gyroscope mode, the azimuth will drift slowly. In magnetic mode, the Earths magnetic field can be distorted by nearby metallic objects and give incorrect azimuth readings. For Indication Only.

Was a great app under Android 8. After Motorola offered to upgrade my phone to Android Pie, the app stopped working. The app's controls flash briefly on the screen, then the camera view is ovelayed on top, blocking all controls from view. Can no longer use the app as is, sadly. But hey, Pie broke a number of apps in my phone, so it's doesn't seem to be GP's fault.

It says "Unable to initialise magnetic sensor" although my phone has a magnetic sensor and works for any compass app. The other features work very well and I found it to be useful.

..as a longterm fan of Keuwl (line) i'm sad that with the switch of the Phone this app started to missbehave.. PNG (alpha) Geo Overlay is not redered, instead RAW output from Rear Camera is shown.. I may falsely suppose the problem is in .renderer.camera class but pls release Screen Ratio fix for non 16:9 devices.. thnx.. 1920 x 1080 is a 16:9 21:9 ("Twenty One by Nine") is a consumer electronics (CE) marketing term to describe the ultrawide aspect ratio.. source: wikipedia
