Dioptra™ provides the following information like a theodolite optical instrument -
• yaw indicator (compass)
• pitch indicator (tilt degrees)
• roll indicator (tilt degrees)
along with -
• GPS position
• azimuth and bearing to photo subject

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.

I use Dioptra often to "characterize" trail segments for slope in order to provide less-than-able people information where to go to enjoy the outdoors. I second all the good enhancements others have suggested and that Nanomics has put on the upgrade list. Please add one more: the white font color is nearly unreadable in normal daylight so making it chrome yellow or similar (or adding font color to the Settings menu) would make the data snap out.

Straight up groovy. This app is awesome. Only a couple suggestions. 1 - selecting font color because sometimes the background makes it hard to read in winter landscapes. 2 - camera zoom. 3 - an image mark up to so you could draw dimensions on the picture to show clients distances between certain objects without driving to the job site... But this is an amazing app. Good job developer.

nice concept i9505 s4 problems display roll and pitch.i allready do the 8 patern movement and still showing bad numbers.maybe a flatback and upright calibration sesion if you can ad as manual calibration or permit to corected in settings as numbers with + or - in front.

Daniel Matthews

Useful Could do with damping control. And to eliminate having to calculate between two points, if this app could lock onto a target and calculate the results as you aim at other targets, showing a small red dot on the first target and a pointer when the dot is no longer on screen would make this app as near perfect as device limitations could allow.

Michael Grady

Nope, sorry, no better than a beta version No UTM? No other lat/long formats? No way to manually set declination to a decimal value (only integer values) and no no east/west declination indicator? Reticle too thin and doesn't extend completely across the value scales. This should not have been released at this stage of development.

Robert Nurse

Exactly what I want This is perfect for landscape photography! Knowing the elevation (in degrees) of sun- and moonrise is one thing. Know what that actually looks like before hand is another! And, as mentioned elsewhere, it would be nice if we could darken the font color. In daylight, it's unreadable to us old fogies.

Good but can be perfect White letters are hard to read when photo background is sky with clouds. It shoild have the options to turn letters and coordinates to black. Better yet the color of coordinates and numbers should automatically change depending on background.

David Paul February 9, 2017

Using WGS84 coordinates helps verify location and field photos. Sometimes the information like lat long is not legible because the background is white like the text. If there was a way to change that in settings this would be 5 stars!

Glenn Zucman May 31, 2016

Fantastic app. I tried a bunch of others that either didn't work, didn't have the data I wanted, or in most cases, were just ugly. Dioptra has great on-screen info that is beautifully and elegantly displayed. 2 issues: 1. App crashes every 3rd frame I take on MotoG3 2. Tiny camera button is a real pain to try to hit. I wish it could snap with the volume buttons like the native camera does. Or if that's not possible at least a bigger button or touch anywhere on screen. To be fair these 2 issues are quite a pain. But I've given it 5 Stars anyway because it's a great app. As I said, the information display here is so much better than any of the other apps I looked at. I'd love to see these 2 issues resolved, but even as it is, it's fantastic.

NW and SE Bearings Incorrect Pretty good. Except the NW and SE Bearings are not correct. Your code is computing those incorrectly from azimuth. Also, it would be nice to export the photos to kmz.

Eyes Wide Open February 3, 2017

Perfect for calibrating distance and positioning of stars and other sky anomalies in the night and evening sky! Thanks to my friend Paul for the recommendation and developers for the app! Love it.

Michael Kirkpatrick June 8, 2016

Great! Very useful in land surveying if you want to avoid using heavy/expensive equipment for quick information.

Les Larson September 19, 2016

Excellent for Site Inspections This app allows me to document vegetation progress over the years for sites that have been reclaimed. I love the features. It is a must have for anyone working in the oil and gas industry.

Matthew Rhodes July 10, 2016

White writing against a white background is hard to read, suggest the font has a thick black outline for ease of reading text on the photo, or that the writing has a black background behind it.

Fernando Rivera December 21, 2016

No gps fix The app have gps fix problem i have a lg v10 running android 6.0 and the app does't show the coordinates will give 5 stars if you fix the problem , the app is amazing just minor fix and will be perfect.

Andrew Koerber July 13, 2016

Change mgrs I do like this app; however the MGRS datum is incorrect for my location. Can this be changed? Thanks

Nanohmics July 13, 2016

Send me an email with your location and I'll check it out.

david marsh February 4, 2017

This is awesome. Since I've become a flat earther, this app is essential for sun and moon Azimuth, bearing and altitude readings. It's really accurate too depending on your phone.

John Mion September 22, 2016

Hurray, it's been updated since I last used it. Captures the screen information (compass and such) with the image. Very handy app. Could use a way to change text color.

pedro Nonofyourbusiness December 18, 2016

Not even close on my S5 OK ... I'll take my gripes back, somewhat .... after playing with it for 10 min and actually hitting due north it has corrected it's misfunction and missinformation and now provide accurate azzimuth/bearing info ...... in the beginning the compass values change based on vertical rotation of my phone (Smsng S5)... keeping it in 'camera position' I can move 90' and get a 1' variance ... so for now I'll move it up to 3 stars & we'll see

Witold Rakoczy December 14, 2016

Total crap According to the indicators you cannot turn your tablet vertically 😂 ~87 degrees i the max! Uninstalled.

glenn whittington December 29, 2016

Good enough. No complaints. Good as what one could expect on a phone without using all the expensive, proper gear.

April 30, 2017

Needs to have setting for reticle and info colors. White is not always good.

Dug Stokes April 9, 2016

Just aligned my satellite dish perfectly first time! Very handy app!!

Caley Campbell May 4, 2016

Liked it Wish I could get UTM coordinates then I would love it.

Peter John September 8, 2016

Fantastic Screen Layout Perfect for geo ref photos, no on screen ads!

Richard Saunders May 23, 2016

Didn't work Didn't work on the Samsung S2. I would have loved to function well.

Marco Lackovic July 22, 2017

It does not auto focus

Vhezhedrick Abjzaiel Acosta September 21, 2016

My Gold Star For Your Excellency Good job developer and thanks for sharing us of useful apps

Sam Tai September 1, 2016

Nice I found here from AngleCam App. You both are good camera applications.

Richard Thompson May 20, 2017

Great tool to have that combines several instruments to use for still photographs.

Terry Hill June 2, 2016

Works great Good for satellite work

Michael Styman December 1, 2016

no zoom?

Shashikant Jadhav August 9, 2016

Good App Good app but there should be option of hiding angles in final image.

Joel Harris June 17, 2017

Like it. Going to find the acuracy at work, in inspection.

Caleb R October 20, 2016

This app is simple yet extremely effective!
