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 (AR) 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 photos and movies with 2X-8X zoom. Overlay geographical data, angle markings, 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 image files self-contained data records. Third-party apps can tap into Theodolite's advanced camera functions with a camera sharing feature. View current position on the built-in map with optional offline Outdoors maps that include topo contours, 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 in the main viewfinder. 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 including team land surveying, accident investigations, spotting wild fires, triangulation of landmarks, and advanced tactical observation and targeting. With an optional in-app purchase to enable team tracking, you can share location with up to 20 people on Theodolite's map. Theodolite includes features for serious users like a reference angle mode, nav calculator, map marker import/export, manual and automatic data logging with CSV and KML export, clipboard integration, %grade display, mil compass readout, optical rangefinders (including a mil-based reticle, sniper-style stadiametric graphs, and a variable 4X-24X scope), and night filters to improve use in dark conditions. 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, Map Grid of Australia, 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. AR Layers include navigational aids like the sun, moon, and Polaris (North star), and the optional US Mountain Summits layer that shows over 70,000 US mountain summits in the viewfinder. 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? Note: Theodolite is an iPhone app -- see “Theodolite HD” for use on an iPad. And be sure to check out the all-new "Theodolite for Watch" and put Theodolite on your wrist!
I’ve been searching for an app to help me plan photographing the solar eclipse on 10 June 2021. I need an app that will tell me accurate and precisely what the azimuth of various features so I can determine exactly where the Sun will rise. This app does that. The key to the accuracy is that this app allows you to manually calibrate the app to a known azimuth, such as the sun. And your can turn off the accelerometer and rely upon just the more accurate gyroscope for maintaining accuracy over a short period of time. The display of the app is remarkable. I am extremely impressed by the work the developer has put into this app and his other apps.
I’ve been using this app for 6+ years and find it a valuable tool when out in the field. It saves me time from using my hand held gps then having to take a picture of the position. I have recommended this app to my colleagues for documenting archaeological subject matter. It’s well worth time to try it out.
Why does it have to include the actual words “date and time” before the date and time? Isn’t obvious? It just adds unnecessary words. It’s pretty annoying.
I'm a First Responder and this app has helped in many ways. I'm considering buying the app for my team.
A high contrast & larger font setting would be useful for very bright conditions
Absolutely the best app. to record data. I love it. Easy to use. I do a lot of Community science work, so recording data is crucial. Theodolite ticks every button for recording time, place and image.
This app is recommended by my company as being very worth while. For me this app is completely useless and a waste of money but most important is time lost trying to get this thing to work. I would not recommend this as you will never be able to use it. It is like a work of art that you can only look at. Useless.
As a major electric utility serving over 15 million residential customers, we have been using Theodolite for several years when setting up helicopter lifts maintaining our infrastructure. Theodolite has proven to be extremely useful in measuring, imaging, geo-tagging and documenting our site plans all at once. This saves hours in the field and returns that time to lift plan development. In turn, that enables much greater productivity that enhances the return on investment for a dedicated aircraft fleet.
There’s nothing else like this out there. Very useful in all sorts of situations! I love this tool!
Nothing worse than paying for an app and then they just forget about updating it to the new IOS. Glitchy AF with the new update. Horrible! Don’t install until they remedy it. Must be covid. I’ll gladly change my star rating once remedied.
