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 camera images and movies with 2X-8X digital zoom and fast image processing. 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 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 (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 in the main viewfinder. 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 including team land surveying, accident investigations, spotting wild fires, triangulation of landmarks, and advanced tactical observation and targeting. 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, iCloud Drive, or local files), 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 colored lens 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, 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. New for 2019 are AR Layers, including 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.
Indispensable. Been using it for years, time to review it. We do storm water and erosion control and always always have it at hand, always showing it to people, best thing for site assessments, continually saves us from having to go back and measure something. Would you consider an option in Prefs to make the angle readouts announce when they are at zero? Especially the left/right tilt. Hard to see them in New Mexico sunlight sometimes. Or maybe an option to make it bigger when you need to. Thanks for the great app.
I love the app for work as it geotags on the photos BUT just put it on my XR and the app will mot let you close out of it Cant swipe up to close it off the screen Not sure if anyone else has this issue If its the app please fix it as i used it almost daily over the past 4-5 yrs
Well worth the price. Does everything you could ask of a Brunton Pocket Transit, plus gives lat/long data. Lots of options for saving photos too.
I have use this app for many years for a variety of activities and it’s done what I needed to do every time. It’s great that I can share what I’m seeing in a picture.
The uber-geek in me really loves this app. The only shortcoming is documentation. The latest update to the FAQ went a LONG way toward fixing this, but a little more is needed. For example, a screenshot of the app with each component named and explained a little would have been nice (like the different reticles). In all, I really like it...not far from a 5.0 Update...Theodolite finally gets a 5. This app has really matured. The latest updates, especially the in-app purchases with geo-referenced peak names, adds great functionality. If you are an app developer, look to Theodolite for inspiration on developing a full-featured app,. OUTSTANDING!
I use his tool in the context of field work for crisis resilience and also farm planning. From antenna angles in Haiti to field documentation on a farm, this app is my go-to to capture situational awareness metadata. The interface is simple and yet rich in options, and makes an easy chore of capturing or establishing headings, angles, etc. I use it as is or plugging in my Bad Elf external GPS for added precision and helping the iphone battery life. Heck I've even used it to level picture frames but it's not as exciting. Only thing I'd love to see added to the main screen is the HDOP and VDOP - the GPS precision. Very different to capture data with 2m error than 30m.
Love this app. I use it exclusively for work in land surveying. I would love to see a feature that auto sorts pictures from the app into a designated folder in my phone. I am using it with an iPhone and the trouble is that google photos backs up all of my work photos along with personal ones. I can’t seem to find a way to keep them separate
App is built around “in the field” functionality and dedication to simplicity.
Accurate and easy to use. Perfect for getting a quick evaluation of local boundaries.
We live on 30 timbered acres in the Matanuska Valley. I have yet to understand and integrate all the features of this app. in my head. Once I have done so it will allow me to understand more fully the resources I have available and sustainably manage them.
