Theodolite App Details

Theodolite HD 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, and custom notes directly on photos and movies for later reference. 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. 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 for more accurate 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).

  • More than an app, its a pro tool

    By Digeguy
    I have relied on this app when I require a precision tool for outdoor photography. Its got everything and more. I use this when Im hiking alone to record and send location updates to friends and family. They can enjoy the pictures and open the location in google earth and others to see EXACTLY when and where it was taken. Awesome for hike review as well. Well done Team!
  • Solid app

    By NgcJim
    Very helpful for setting up my telescope before it gets dark.
  • Welding inspector

    This app is perfect for recording welds, piping or anything. The amount of information on the picture is outstanding.
  • CRD020

    By Chris UAE
    This is a great product. Use it for doing rapid photo surveys of buildings and it’s perfect.
  • Surveying my world

    By CityGuideSix
    I’m not a professional in any field where this is in constant use, but it has always been the right tool to use in special situations. Whether hiking and wanting a numerically geographic record of the landscape or conducting walking tours in the city and wondering about whether a particular building had a tilt, I always relied on my trusty app to provide the data. With so much information in the screen, it provides a factual and entertaining record that is useful for a long time.
  • Amateur Use ONLY

    By Whenwitty
    Bought all sub packs and walked to several monuments to compare data, all several feet off if not more. Not for Civil Engineers.
  • No updates

    By tomfergy
    This must be the first perfect application that doesn't need updates to keep current with the iOS. No updates since 2015. One stars because I like the app but it needs to stay current with hardware and OS changes.
  • Great app!

    By bbobbzz
    I’ve had this app for quite a while and love it. It has a lot of information all brought together in a handy way. I use while hiking using it and my USGS 7.5 minute topo maps (or the Topo Map app). It uses the iPhone camera, so I often take a couple of pictures with it to help orient me when I’m traveling or taking photos in unfamiliar territory. It’s a survey and navigation tool and has a lot of data on each picture, not designed to replace your camera. I have not had any issues with it, and it’s GPS and compass correlate well with the GPS and compass on the iPhone and the Topo Maps app.
  • Great App

    Works great, cool features. Easy to understand and use.
  • Field Geologist

    By GeologyTom
    If you are a field geologist who hasn't integrated this app into your workflow then you should.
