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.

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.

One compass to rule them All

This is a powerful app without crass commercial distractions. It is a powerful navigational tool. Valuable to hikers, hunters, rock hounders, cyclists, automobile GPS, boaters, and any others who wish to use the most comprehensive compass based navigational tool for iOS.
Built in accurate calibration with celestial objects, moon, sun, and Polaris (viewed thru your device's camera) is in addition to the GPS compass toolset that other navigational apps use.
Great map overlays, satellite maps, and ability to share locations to other spyglass users. You can also share to users of tomtom , wayze, google maps, and other GPS and maps systems.
Very cool.
As long as you have battery life, you will never be lost with this app.
There is a learning curve. If you can read and comprehend on a 20th Century 7th grade level, then you can learn how to use Spyglass. Great videos and comprehensive manual. Use them to get the most out of the app.
I rarely leave reviews, but this app deserves its props and unabashed accolades. Bravo to the Spyglass team.
Top quality, the definitive compass and navigational tool. Buy it and be done in this genre of apps.

Not holding saved location

I just downloaded this app for remote area use in a very vast forest hunting area, but first I decided to test this on my property because getting lost and not able to find your vehicle is a very scary feeling!!! I put up a post holding it up in the air with a concrete block, I add the current location as taught by the videos, I walked 200 yards away, the app showed the post that it was on the ground in front of me on the ground when the post was 200 yards behind me. At first I thought I did something wrong, I tried it again marking the post area from the ground or to the tip of the post in the air. Still same result, I tried a different target which was my personal vehicle, this time I saw the marker to my truck literally glitch slowly moving to the east. I thought this app would help me get to my vehicle i mean it said off road, wilderness, but I guess they DIDNT MEAN OFFLINE! I was shocked that this app wasn’t dont what I thought it would. I’d like a developer to contact me, in the meantime I’ll be buying a map a REAL ALUMINUM COMPASS, and ranger beads!

please check location permissions in the iOS settings - you should allow "precise location" for the app
