Theodolite

***** 40%-OFF SALE ***** Theodolite is on sale for 40%-off to celebrate its seven year anniversary! ***** As seen in Apple's Special Event Keynote, Theodolite is a multi-function viewfinder for iPhone and iPod touch that combines a compass, two-axis inclinometer, rangefinder, GPS, map, nav calculator, tracker, and geo-tag photo/movie camera into one indispensable app. Uses are endless, and the app is great for hiking, boating, hunting, golf, outdoor sports, sightseeing, navigation, and finding your way around. Theodolite 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 geo-tagged camera images, screenshots, movies, and screen movies directly from the app, with 2X and 4X digital zoom and fast buffered saves. You can choose to overlay geographical data, time, date, and custom notes directly on photos and movies for later reference.

View your current position on the built in map view, with optional new Outdoors maps that include topo contours (feet or meters), roads, trails, landmarks, campgrounds, ski lifts, and more. Custom "live" map markers continually update distance/heading relative to the current location. Share map markers and nav calculator points with other users of Theodolite and Theodolite HD via SMS text messages and 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, a nav calculator, data logging, e-mail export with KML, 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. The app can provide location in military grid reference system (MGRS) coordinates, universal transverse Mercator (UTM) coordinates, British/Irish National Grids, US National Grid, 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 and altitude 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 teams to offer a good balance between simplicity and performance.

Theodolite has been featured several times in iTunes in "Rewind: Hot Trends in Apps", "The World Around You", and "New and Noteworthy". It 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.

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 or iPad mini). Note: GPS and compass requires an iPhone. iPod touch devices do not have GPS or compass hardware.

Theodolite Reviews

Squirrels & Bacon

UPDATED: NOT a Total Ripoff after all  Squirrels & Bacon  5 star

Update on my complaint about in-app purchases back in January: wow, major kudos to HTR. I just got a personal response from a developer regarding my review - that's never happened to me before and shows that these guys really do read these reviews and respond to customers. They explained the in-app purchases and why they need to do it that way (no, they're not just hitting you for more money). I have to change my review from one to 5 stars. Customer service goes a long ways, especially personal responses. Obviously this app is awesome and does lots of cool things. I was frustrated about the in-app purchases that didn't seem clearly explained, but HTR got it right. Again, major kudos and you guys get 5 stars. Thanks for taking the time to explain. 👍🏻👍🏻👍🏻👍🏻👍🏻

In need of refresh (Apr 2017)  Dimsum99  2 star

Can't select between iPhone 7+ cameras, doesn't shoot full resolution, would be nice to support RAW & use vol buttons for snap.

Awesome APP! Next step would be to integrate a topo map.

BHunted

Great app  BHunted  4 star

But we are over due for an update to get it to specs.

Cougrick

Very Useful  Cougrick  5 star

I have used this app many times to document infrastructure items in the electric utility industry. Elevation is particularly helpful.

WTadPf

Fascinating & fun  WTadPf  4 star

And a good pedagogical tool (I teach surveying)

Fishdoctor2

Where are you?  Fishdoctor2  5 star

Great app to provide you detailed information on your location relative to the surroundings. Also great for documenting photographs that need location information as part of a record. Highly recommended.

JuneauB

Crashes current iOS version.  JuneauB  1 star

I used to love this app, but twice now it has totally crashed my phone and rendered it unusable. It drains the battery in such a way that the phone acts as if it were totally dead. I started using it at a 75% charge and within 5 minutes my phone said it was out of battery and would not turn back on. Once I plugged my phone in it then said that the charge level was at 67%. Strange right? DO NOT PURCHASE THIS APP UNTIL THERE IS A UPDATE!! I will be looking for a replacement for this one as soon as I submit this review.

the good nick names are taken

Great app!  the good nick names are taken  5 star

I made a hood out of tar paper that fits around my cell phone to make the cell phone display more visible in sunlight

Babzyy_gurl

Freaking terrible  Babzyy_gurl  1 star

This is by far the worst app ever. I would honestly like my money back the range is not correct. When I stand not even 5 feet from something it says I'm over 500 feet. It really deserves no star but unfortunately I have to give it one.

The win

Theodolite app compass no longer works in IPhone 6s  The win  2 star

Really enjoyed this app with iPhone 5 however, after updating to IPhone 6S the compass is always reading north in any observed direction. All of my other installed Apps show the correct observed direction and are working correctly. Appears not to be calibrated, although all of the indicators, green radio knobs, indicate that it is.... Hopefully there is a quick fix!!!!

Kickasaurus

Love it  Kickasaurus  5 star

Incredible app with a lot of different uses.

Mac_Doctor

Great App  Mac_Doctor  5 star

I use it to remember and document locations I have visited. Works great.

Goatbuster

Well designed multi functional app  Goatbuster  5 star

Works well as a clinometer and useful for recording information on a photo relating to a specific place. I use it to map things like small infestations of invasive weeds on my ranch so I can come back later and deal with them. I don't need all of the capabilities and have tried several simpler apps, but keep coming back to Theodolite because it works better.

WeatherFreaky

At First I Had No Idea  WeatherFreaky  5 star

When first I started with this app I couldn't pro ounce let alone figure out what it could be used for. Now in my professional life it has been a remarkable tool. And backpacking and trek ING it has been an great app., with all kinds of useful tools. You will enjoy it!

gadgetklm

Extremely useful, even though the learning curve is a little steep. Highly recommended.

Predist

Awesome  Predist  5 star

This app is great and is a gift to assist me in my endeavors throughout the country

Ghenley

FUN APP  Ghenley  5 star

This is an enjoyable fun app to play with. It could be useful for a number of things, both pleasure and professional. As a ham radio operator I find it useful for aligning a beam antenna at a fixed point on the horizon.
