Theodolite for Watch vs NRST Usage & Stats

Theodolite was one of the earliest augmented reality (AR) apps for iOS when it debuted in 2009 -- in fact Theodolite was pioneering AR technology before "AR" was even a buzzword! In the time since, Theodolite has been used by millions of consumers and professionals in their outdoor adventures and on the job. Now, we've taken the Theodolite concept to Apple Watch by combining a compass, inclinometer, GPS, and maps into one indispensable app that sits on your wrist. We're excited to keep evolving this centuries-old instrument as hardware and software technologies allow the concept to come to new device formats. On iPhone and iPad, Theodolite uses a viewfinder format, uniting the device sensors (GPS, magnetometer, gyro, accelerometer) and camera. On Apple Watch, Theodolite combines data from these sensors into an AHRS (attitude and heading reference system) layout similar to what you'd see in the glass cockpit of a modern aircraft. This layout allows Theodolite to efficiently display compass bearing (yaw angle), pitch angle, and roll angle in a compact format that works extremely well on a small screen. This information is augmented by latitude, longitude, and altitude from GPS, as well as sun and moon position. New in Theodolite for Watch version 2 is a map screen and waypoint manager. You can add waypoints on the map or at your current location, and view waypoints on the compass ring to visualize their bearing from your current location. Theodolite has settings for compass mode (true or magnetic, degrees or mils), distance/altitude units (feet or meters), and position format (decimal degrees, degrees-minutes-seconds, MGRS, USNG, UTM, UTM-B, and Maidenhead Locator System). Users can choose to display an artificial horizon in the center of the app display (tied to pitch and roll) and can set the app's level reference to flat or vertical orientations of the Watch. The app has six color schemes, including two night vision modes - midnight red and luminescent green. Theodolite for Watch is recommended for Apple Watch Series 5 and later (including Ultra). Apple Watch Series 4 and older do not have a compass sensor and will not show compass data. On older devices, the app uses the device's gyro sensor to measure rotation. You can twist the watch's digital crown to adjust and calibrate the gyro to the sun position, moon position, or a known bearing. Using these references, the "gyro compass" is able to give bearing. The calibration can be repeated as often as desired to give accurate results. Theodolite reports accuracy from the magnetometer sensor in your Watch. To improve results, operate Theodolite away from magnets, electronics, or sources of electro-magnetic interference, including car dashboards, aircraft cockpits, metal structures, and other devices. Like all our apps, we plan to continually improve and evolve Theodolite for Watch. Please contact us with feature requests, suggestions, and general feedback. We'd love to hear what you're doing with the app! And if you don't already have Theodolite for your iPhone or iPad, check it out!

NRST

Don't miss your airport! Designed for pilots of any size aircraft, this app provides you with bearing and vertical speed required to nearby airports. The following information is shown for destinations: • Distance from current location • Field Elevation • Descent rate required • Time to Top of Descent (TOD) • Bearing • Frequencies • Runways • Glide distance delta Additionally your current speed, course, altitude and vertical speed are displayed. Tapping on the information button, Time to TOD or Target Altitude allows you to customize the desired descent rate. All data is updated in real time as you fly. You may choose a nearby airport or select an airport by identifier by scrolling down on the airport list. Filter by runway length and surface type and choose any of the following: airports, seaplane bases, heliports, balloon ports and closed airports. You may optionally provide a glide ratio for your aircraft. The glide distance long or short of the selected airport is then displayed and is conveniently color coded. A positive, green glide delta indicates the glide distance has been estimated to exceed the distance to the airport with a 25% safety margin. Runway headings, if known, are used to draw runways on the heading indicator. If the magenta arrow is pointed straight up and aligned with a runway then you are headed straight in. Worldwide airport information is provided by multiple sources. Canada, Europe and all continents are covered! For more information go to ourairports.com/world.html. Database updates are performed daily. Your location and altitude is provided by your device's location services. If location or altitude is not available that information will not be displayed however you can still search for an airport by identifier. Unfortunately external GPS devices are generally NOT compatible. You must be moving for course information and the magenta relative bearing arrow to be displayed. The Watch app has many of the same features and fits on your wrist. See distances to nearby airports or bearing to a selected airport. Frequencies and runway lengths can be seen with a swipe. A green glide icon or delta indicates glideability is likely. Just like the iPhone and iPad app, the Watch app requires GPS information to locate nearby airports and relative bearing. Additionally, altitude is needed to calculate descent rates. Feedback and feature requests are appreciated. Thanks!
