Theodolite App Description

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).

  • Multiple use tool

    Tool is very handy. Multiple uses from setting up satellite antennas, rough surveys, measurements and photo with info for reference.
  • Great app

    I use this app more than I thought I would...
  • A tool for avalanche forecasters and backcountry skiers/boarders.

    By Joe-lip
    Theodolite is a fantastic tool for avalanche professionals and all backcountry skiers and riders. For the professionals, take a photo of your pit to obtain and record location, altitude, aspect, date and time. Take a side view, tilting to the slope and you have the angle. This shortens the time required to obtain and record data, while increasing accuracy. For backcountry recreational users, use theodolite to determine aspect (some easy math required) and altitude. A side view shot and you have slope angle. Are you on plan for angle, aspect and elevation?
  • Great app

    Works just fine
  • Theodolite review

    Theodolite is great. It's really like a little theodolite riding around in my pocket. Took some shots on a couple of avalanche paths and it worked great.
  • Very Great App

    I use it all the time. I use it conjunction with my phone in locating points and where I am. I also use it like a mini telescope. Gary Brewer
  • Useful for variety of tasks

    By Twz42
    I have had this app for several years. I don’t keep those I don’t use. I use it to level furniture and wall hanging. I have used it as a compass, gps, inclinometer. It has been easy to use and bug free. Definitely one of my favorite apps.
