Support for iOS 6 and iPhone 5. Improvements to map marker sharing. Improved rendering of map markers, compass rose, and azimuth pointer. Live map markers, with realtime distance/heading updates (relative to current position). Map marker sharing and e-mail export integration with Gaia GPS. Improved handling of MGRS, UTM, and UTM-B search/lookup on map screen using format prefixes (see user manual for details). Variable 4X-24X rangefinder scope reticle. SLR camera style round wire reticle with focus prism and exposure indicator. Team tracking available through in-app purchase (see user manual for details).

NEW! Movie recording, with optional screen/watermark overlays and multiple video quality settings. Three large-format stadiametric rangefinders (sniper/artillery/hunter style, showing distance multipliers, yards, or meters). Revised position formats with new decimal minutes option.

Numerous performance improvements and tweaks.

Ability to share map markers and A-B points with other users of Theodolite Pro and Theodolite HD via SMS text messages and e-mail. To access this feature, tap any marker shown on the built-in map, and then tap the "Share" button on the marker's popup. Data shared from normal markers includes position and marker name. Data shared from A or B points include position, altitude, azimuth, elevation angle, and horizon angle. This allows users to share A-B measurement points for distributed and team calculations.

Fixed bug in storage of map markers and added rangefinder lens specs for the iPhone 4S.

Combined distance/height calculation in A-B calculator. Data logging feature with clipboard integration and e-mail export.

The calculator includes an option to copy results to the clipboard. Theodolite will save observation data for point A if the app is quit before recording data for point B.
* Zero Reference mode to show relative angles
* Option to take screenshots from camera button
* Option to show/hide crosshairs on saved photos
* Option to write custom note/text on saved photos
* Status message displayed while image save in progress
* DMS option for latitude/longitude format
* Revised time/date to better capture local/national formats
