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 (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, planets, 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!

An excellent tool

Provided of course that you make sure your phone compass is working correctly, with no steel nearby!.
I made a crude support for my iPhone, and a laser distance measure to mount on the head of a Manfrotto tripod; a kind of very crude “total station” for a home driveway survey and drawings, but I neglected magnetic attraction between the phone and the laser, and the screws in my contraption. As a result all my bearings were useless!
Not Theodolites fault of course! An excellent tool

Spurious orientation measurements

I’m a relatively new user and I was working through validating and verifying the dip and azimuth data displayed. I used Apple’s Compass app and Field Move to check my measurements. I found that Theodolite was producing spurious values. What’s more, while checking these values I found that the other programs would start to produce spurious values after I initiated Theodolite and switched between them. I restarted the phone and Compass and Field Move were reliably showing correct readings. But as soon as Theodolite starts, the values become spurious. Additionally, when I lay my phone down, the tilt values jump around all over the place. The look and feel of the app is excellent, please address this critical issue and I would be more than happy to increase my rating! At the moment, it is unusable.

Great

Almost perfect.
It does everything it says it does very well.
If only I had the option to create a 1 second interval track file within the app then I wouldn't have to keep swapping between Theodolite and a simple track logger when I was in the field collecting data.
