Spyglass is an essential offline GPS app for outdoors and off-road navigation. Packed with tools it serves as binoculars, heads-up display, hi-tech compass with offline maps, gyrocompass, GPS receiver, waypoint tracker, speedometer, altimeter, Sun, Moon and star finder, gyro horizon, rangefinder, coordinate converter, sextant, inclinometer, angular calculator and camera. It saves your custom places and waypoints, navigates precisely to them later, shows them on maps and using real-time augmented reality displays detailed GPS info, measures distances, sizes, angles, and does a lot more.


Accuracy improvement techniques, special compass modes and calibration methods available in Spyglass only make it a real instrument – the most advanced and accurate digital compass.


Spyglass operates in 3D and uses augmented reality to show real-time object positions, info and directions to them overlaid over camera or maps.

Save current position, add points from maps, manually enter location coordinates and bearings, add stars by hand or use a built-in star catalogue.

Find saved places and objects later simply by following directional arrows.

Spyglass tracks multiple targets simultaneously and shows their info – distance, direction, azimuth, elevation and estimated time of arrival.

Copy, paste and share locations, coordinates and map links using many supported formats.


Find and track your location and get detailed real-time GPS data – coordinates in dozens of formats, altitude, course, current, maximum and vertical speed, using imperial, metric, nautical and surveying units.


See your and targets’ positions on maps using different map styles and alternative map providers – plan waypoints and measure distances. Offline maps optimized for retina displays are available for download.


Track positions of stars, Sun and Moon with arc second precision – use them as a reference to calibrate compass for maximum accuracy.


Measure distances to objects in real time with a rangefinder reticle similar to sniper sights.


Find out heights of objects and distances to them – measure visually and calculate dimensions and distances.


Take pictures overlaid with all available GPS, positional and directional data.

Everything a good compass can do but…

Years later and I still live this app. I also still wish you could orienteer like a real compass. All it needs is a direction of travel line, and an orienteering arrow (that little house to keep the needle in) and a way to turn the bezel to a specific azimuthal (without moving the map).

Happy to resend screen shots of what it could look like if that helps. Original review below:

It lacks a direction of travel line and an orienteering arrow. You can certainly shoot an azimuth by setting a way point, and can see direction of travel once you start moving but… It would be nice to be able line up the direction of travel, the needle, and orienteering arrow; then two finger turn the bezel to say 10°, turn your body until the needle is inside the orienteering window and walk following the direction of travel line. Should be an easy UI update. It also lacks a ruler, which I imagine is harder to implement with all the different screen sized (or need to calibrate it) and wouldn’t be easily used with a paper map (and not needed for a digital map). This is a full featured compass that makes use of all the phone sensor data and map data and nicely integrates gps, gyros, and accelerometers. it even emulates a site glass when you hold the phone 90° and “look” through the phone screen.

Developer Response ,

WOW ) Thank you for the warm reply and detailed suggestions. I'll add the direction of travel line/mark on the bezel with the soon coming update. Took a while for it to come to me as I rarely read comments. Messaging directly via the support button in the app would work a way faster :]

Elite Quality App

This is one of those rare apps that you come across every so often that truly demonstrates the power of what an application on a smart phone can do. I personally have only come across a handful of apps that are what I consider "elite".

This App works flawlessly. The design is very slick and minimal which I equate to quality. I could honestly see this application being something that you would see on a screen in the cockpit of a jet aircraft. After using this app for only a short time, it becomes obvious that the creator of this app has the Swift/Objective-C programming language mastered. I honestly wish that the author of this app would create a Celeste you'll start tracking app as I know it would be five stars as well. By this up with confidence if you are looking for a top-tier application that turns your smart phone into a precision measuring instrument.

Great tool

Calibration using visual land marks, satellite aerial map and sun make this a very accurate tool. Accuracy is there if you know how to set it up. Metal is no longer an issue when finding an azimuth. Remote tree and building heights is another favorite use of this powerful tool. Take the time to learn this app. Still using frequently and am really impressed. One improvement would be an option for large text for Bering. Or a separate azimuth mode with larger bearing text.

Years later I still use this app. In fact, it’s only app I pay money for. It is worth it to me. I install communications equipment, and when I have to set specific directional antenna path, I use this tool where I can literally put my phone on the back of the antenna and hit the target, after a local calibration. It works so good.
