Theodolite App 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).

    As a very active hiker and climber here in the Colorado Rockies as well as a member of Search and Rescue, I rely on this app to help confirm my location. I particularly value all of the data that can be imprinted on photos taken. Brilliant tool!

    I’m an archaeologist and while this doesn’t replace sub-meter accuracy GPS, it is a great general field tool for documenting initial finds.

    I use this all the time for my wetland delineation field work. Professional quality data, screenshot feature is invaluable and the mapping portion is fantastic.

    In an area of boreal forest flat muskeggy and zero landmarks theodolite was essential to make sure our footprint remained within our permit area. I checked it with our surveyor, within 1.5 meters laterally and 30 meters vertically. Pretty amazing for an iPhone app. I heartily recommend it!!!!

    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.
