Theodolite 7 lays the groundwork for the next several years of development. The app introduces it's first AR layers, including navigational aids like the sun, moon, and Polaris (North star), and adds a brand new in-app purchase that shows over 70,000 US mountain summits in the viewfinder. These AR layers support Theodolite's new compass correction mode, which lets you slide your finger on the screen to correct compass errors and offsets by aligning the compass with known references. Theodolite 7 brings improvements to night modes, makes it easier to find and buy in-app purchases, and has numerous user interface improvements and tweaks throughout the app. Support for all the latest iOS devices has been added.

Great ap for construction and mapping
This is a great app, let me share an example; a small city i was employed at had just resurfaced most of the asphalt roads. I got a call from the boss about some truck leaking hydraulic fluid on our newly surfaced roadways. If you dont know hydraulic fluid is like a solvent for asphalt and creates holes and ultimately will lead to a failure in the road surface if the fluid leaks enough.
It was not long before i picked up the trail of the culprit, a local garbage truck , caught up to the driver of the leaky truck and informed him he was leaking hydraulic fluid and made him turn off his hydraulic unit and go back to his shop and to inform his boss of the occurrence. It wasn’t long before his boss contacted me and argued with me about the extent of the damages. I provided a map of the trucks route and pictures with times, gps locations. Argument over, but the boss wanted to know how i recorded this stuff. Showed him the ap and i think ,he’s a customer too. I know all the guys on my engineering staff purchased this ap and use it to record all kinds of data, great ap
This is my favorite app. I most recently used it to find a Forest fire that had gotten within 3.1 miles of us. I took photographs at various places in the burnt area and then plotted the location on a Quadrangle map.
But my main use is to record the location of petroglyphs in remote ( and not so remote sites) in the far west of the U.S. And Canada. Of course in some places satellite connection cannot be made but most of the time it can be. Not only do I get the time and the longitude and latitude and elevation, but also the azimuth. This latter is important because by adding 180 degrees to the reading I can tell what direction the petroglyph is facing. By placing a measuring graphic near the subject the theodolite photo also displays the size of the petroglyph. The theodolite record is redundant because I usually take more photographs with
a camera, which includes the time and sometimes the coordinates, but never the azimuth or elevation. This along with iPhone Notebook allows me to travel lighter and scramble in the rocks more safely.
Excellent tool for navigation and documenting important places
This app is both fun and useful. If you ever need to show exactly where something is, or show that you did that job out in the back forty, this app will provide a photo which includes all the information you can possibly imagine- exact latitude and longitude, bearing, altitude, time, date, inclination in 3 dimensions. In principle someone else could very nearly stand in your exact footprints to see the scene, based on the photo.
Another useful function is as a Sight Level. I put some bright tape on a tree or the side of the house at my eye level. Using this app I can move around and if I can see the tape I can tell within an inch or so my elevation relative to the tape. This helps with landscaping my yard, for example.
So if you are a contractor, forester, or investigator, this would do a nice job for you.
I use this app with Boy Scouts, not only for a handy compass bearing, but also for questions like, “If that tree were to fall, would it hit my tent?” (Hint: 45 degree vertical inclination). Or, “How side is that river?” (Classic map & compass exercise.)
I cannot evaluate the accuracy of the measurements (apps are notorious for displaying way more accuracy than they really can achieve), but they seem good for my purposes. If you have a boat with good navcom, check the accuracy and let us know!
I use it a lot and like it a great deal, and yes, it IS a great deal at this price!
