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.

Ratings and reviews

Saves all kinds of useful info in the photo (visable, not just EXIF header), like GPS, direction you are facing, angle, tilt, time, etc. Like a land surveyor's instrument. Not for every picture you take, but perfect for legal or historical or engineering matters. My initial review complained about not being able to move the app to the SD card, which I later found out was because newer versions of Android prevent it (so you can't buy an app and then share it with someone who didn't pay).

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).
