Description

Theodolite is a multi-function viewfinder that combines a compass, two-axis inclinometer, rangefinder, GPS, map, nav calculator, and geo-overlay photo/movie camera into one indispensable app. Theodolite was one of the very first augmented reality apps when it was released in 2009, and it’s been downloaded and used by millions of customers since then. Uses are endless, and the app is great for land measurements, outdoor sports, sightseeing, navigation, and finding your way around. Theodolite is a pro grade app and is used extensively by surveyors, geologists, architects, engineers, competitive sportsmen, first responders, military personnel, and search and rescue workers around the world.

Theodolite lets you take data-overlay camera images and movies, with 2X-8X digital zoom and fast image processing. You can overlay geographical data, date, time, author/company info, and project notes directly on photos and movies for later reference. The same data is written into the metadata record of images, making the image files self-contained image+data records. Third-party apps can tap into Theodolite's advanced camera functions with a new camera sharing feature.

View your current position on the built in map, with optional new offline Outdoors maps that include topo contours (feet or meters), roads, trails, landmarks, campgrounds, ski lifts, and more. Live map markers continually update distance/heading relative to the current location and also show wayfinding info on the main camera screen. You can draw polygons on the map to mark things like property boundaries and trails, and import/export polygon data via KML.

Share map markers and nav calculator points with other users of Theodolite via text messages or e-mail. This powerful capability opens up a wide range of collaborative uses which include team land surveying, accident investigations, spotting of wild fires, triangulation of landmarks, and advanced tactical observation and targeting operations.

Theodolite includes features for serious users like a reference angle mode, nav calculator, map marker import/export, data logging with CSV and KML export (via e-mail or iCloud Drive), system-wide clipboard integration, percent grade display, mil compass readout, optical rangefinders (including a mil-based reticle, sniper-style stadiametric graphs, and a variable 4X-24X scope), and colored lens filters to improve use in dark conditions and preserve night vision.

Theodolite can provide location in military grid reference system (MGRS) coordinates, Universal Transverse Mercator (UTM) coordinates, British/Irish National Grids, US National Grid, Maidenhead locator system, and six latitude/longitude formats. Optional US State Plane coordinates include SPCS27 and SPCS83 zones covering all US States. The optional Datum Pack adds over 230 geodetic datums to the app to improve position computation from GPS data, covering regions and countries on all continents around the world.

With an optional in-app purchase to enable team tracking, you can share location with up to 20 people on Theodolite's map. Team tracking was developed in conjunction with search and rescue experts to offer a good balance between simplicity and performance.

Theodolite has been shown in Apple Keynotes, featured on the App Store, and has been a #1 selling Navigation app in App Stores around the world. Since its introduction in 2009, Theodolite has defined augmented reality navigation. The app continually introduces new technologies, pushing the limits of iOS app development and taking advantage of new hardware capabilities.

Find out why Apple named Theodolite one of the most amazing apps available and showed it being used to explore the Great Wall of China. Where will you take it on your next adventure?

Theodolite requires an iPhone or iPod touch (see the “Theodolite HD” app for use on iPad).

Theodolite

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.

Fascinating application

Theodolite Pro is a fascinating application showcasing some of the abilities the iPhone is capable of. Whether playing around and curiously experimenting, or seriously putting your iPhone to work, it's surprising to find quite a few uses limited only by one's imagination.
So far the application has worked flawlessly and been extremely accurate.
Great job!!
This app would be a great gift to a student learning geometry, or an outdoors person with a curious nature, or just someone who likes to experiment. I've seen lots of articles and apps about compasses , levels, protractors , and similar devices. None that I have read about or used can match Theodolite.
Additionally, Theodolite is a well thought out app with a great user manual. I haven't had an issue or crash using Theodolite on a 3GS, 4S, and 6 Plus on their various IOS versions. This is one app that will stay on my device.

UPDATED: NOT a Total Ripoff after all

Update on my complaint about in-app purchases back in January: wow, major kudos to HTR. I just got a personal response from a developer regarding my review - that's never happened to me before and shows that these guys really do read these reviews and respond to customers. They explained the in-app purchases and why they need to do it that way (no, they're not just hitting you for more money).

I have to change my review from one to 5 stars. Customer service goes a long ways, especially personal responses. Obviously this app is awesome and does lots of cool things. I was frustrated about the in-app purchases that didn't seem clearly explained, but HTR got it right. Again, major kudos and you guys get 5 stars. Thanks for taking the time to explain. 👍🏻👍🏻👍🏻👍🏻👍🏻

Developer Response

Offline topo maps were the #1 requested feature from our customers for many years, and finally came to the app in version 5 as an in-app purchase. The map tiles (which are very high quality) come from a third party, and we have to pay for them, so we pass the cost off to customers on a "per-tile" basis. You only pay for what you use (other apps charge annual subscription fees no matter how much you use). I am sorry you are unhappy about the cost, but we make it clear this is an optional purchase in all of our advertising, as well as the iTunes product listing. We do our best to add features requested by customers, but in some cases those features need to be setup as in-app purchases to make them feasible to implement and support on a long term basis. For additional help/feedback, please contact us through our website (link is included in this App Store listing). Thanks!
