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.

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.

I know it's borderline extortion but I'll give 5 stars when they come out with the Pro version. Perhaps different color options for the reticle as the white coloring tends to get lost in the background of a bright day in the field. Otherwise, please continue to upgrade & support this product. It's perfect for my work usage and I haven't found a similar solution. Keep up the great work!
