The ancient greek "dioptra" was a classical astronomical and surveying instrument, dating from the 3rd century BCE. The dioptra was a sighting tube or, alternatively, a rod with a sight at both ends, attached to a stand. If fitted with protractors, it could be used to measure angles.

This works very well, except one thing could be fixed, please. The readings need an adjustable damping factor to slow down the display so that it is somewhat readable. This is important. As it is, it becomes exhausting to try to take imperical data. Even with taking pictures, it is tedious.

Pretty good app to use. Unfortunately, the compass uses the phones internal compass which can be messed around with if you are near large magnetic objects. Will not always point true north for this reason. Also, having difficulty following the file naming convention. Would be nice if I could adjust a setting for how I want the file saved (Date, Lat+Long, series number).

Nice features but it says it's saving the picture, but I cannot find the saved pictures anywhere. I have uninstalled/reinstalled and checked permissions, everything.... There are no Dioptra photo galleries, and nothing in any other album/folder. I guess taking a screenshot of the frame works... For now.
