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.




Spyglass App Description & Overview

The applications Spyglass was published in the category Navigation on 2009-10-04 and was developed by Pavel Ahafonau. The file size is 18.95 MB. The current version is 3.9.3 and works well on 8.4 and high ios versions.

○ fixed a coordinate parser bug

Supported latitude and longitude coordinate formats are now properly handled when coordinates copied from a text editor, a mail or a web are being pasted into the app as a new waypoint destination. Earlier a hemisphere following the longitude could be omitted in case the hemisphere was the last part of the coordinates.

I like having the camera to mark coordinates.


Excelent  Iluvgames  5 star

Great app  Le' General  5 star

The altitude reading Is very good for navigation using a contour map.


Review  Tsiochain  4 star

I really have no reason to use this app but as a science geek, I love it.


Very capable  itsgonnabealright  5 star

This app can do so much -- much more than I know how to do but am learning. Wonderful and powerful app.


This is spot on  Swatem2u  5 star

Altimeter is spot on also


Fantastic Cross Country Navigation App  pfbentley3  5 star

I've always been very pleased using this app to navigate while hiking. Easy to add waypoints and destinations and the base map is very useful.

Mi Kiwi

The map overlay is fantastic.  Mi Kiwi  5 star

A Very clever we sail in west Michigan it is very handy when going into new ports to help find slips and food etc. a full 5 stars.


Awesome  Mushdogs  5 star

Excellent app. Really like the sextant function. Detailed instruction manual. Functions well on my 5s. Recommending to all my friends.


Ok app. Could do more  BillK12321  4 star

Works. Could add date and time to data for each waypoint. Could easily add a mode to record points per time elapsed--e.g. 1, 5, ... minutes.

Love this app


👍🏼  PhukY0C0ucH  5 star

Seriously no other app comes close. Very accurate! Very attentive to bug fixes and updates.


Amazing  Meshuggah003  5 star

This is one of the most powerful apps in the App Store. I primarily use this tool as a U.S. Army Pathfinder to measure obstacles around helicopter landing sites. There are many useful tools in this app and they are very accurate. Also, technical support is fast and friendly. I had my questions answered within minutes of my initial email.

A great compass - very accurate.

Won't open!  ev's world  1 star

Screen goes black. When I back out of it, it goes right back to black screen. Has this worked for anyone running latest iOS on iPhone 6? How do I resolve issue?


Broken  Feelbettertraveling  2 star

None of the buttons work on the right side i.e. The tracker button is supposed to open menu options, according to the manual. Tapping, pushing, holding down on the buttons do nothing. Can't change to new destination, or any other option listed in the manual. If these were working 5 stars. Right now I am stuck with one destination, and I don't even want to go there!


Well-crafted App  bluequasar  5 star

I’ve had this app, in its various updates, for several years now, and it still is leaving me shaking my head. It’s true that - as some reviewers have said - if you’re in the wilderness and your phone runs out of battery, you would do well to have an old-fashioned iron compass. But this is something far more sophisticated. AR combines bearings, distance measurement (mil scale), fine calibration by position of sun, moon, Polaris…or any of the 100 or so major stars that you can choose. Can be set for magnetic north, true north, “gyro” compass (based on your initialization, just as in aircraft gyro compass), integrates with GPS, stores maps you use once while connected to data. If this were a stand-alone device, it would come closest to some of the high-end TI scientific calculators, in terms of usability, versatility. This dev has done some other interesting apps, too, but while they are extremely detailed, this is the most accessible of his projects. But be sure to print out the manual, and (as he suggests) read it a bit at a time, not trying to internalize it at one sitting.


Great App  cmhendrix1280  5 star

Works wonderfully for keeping track of locations I've visited and new ones that are on my list.

CASH conscious

It's a Toy. A very cool Toy.  CASH conscious  3 star

Works great, gorgeous, well designed. But let's be honest......you're never going to use this thing other than for a cool novelty. No one is wandering into the wilderness with nothing but an iPhone app to navigate them out.....and really no one is wandering into the wilderness period. You're going to pull this thing out and show your hunting buddies how cool it is, or use it to waypoint your way from the bar to the urinal and back. That's why it's so cheap....I bought it just because it looks cool and makes me feel like I can go spelunking. If you claim this is an essential tool to navigate your off-road adventure or next wild camp outing, then you need to get a different hobby.


Worthless On iPod Touch 5  uranographer  1 star

Don't get lost with this app on a iPod Touch 5. If you do make sure you are constantly recalibrating it. Only works in gyrocompass mode on iPod Touch 5. Gyrocompass mode requires that you know the cardinal directions in your location or that you have relatively clear skies, in order to calibrate it. If you know the cardinal directions then you don't need a compass. If you don't have clear skies and don't know the cardinal directions in your location, can't back track, or you're in unfamiliar terrain, then sit down and stay put because you're lost and this app ain't going to help you. Hahahaha! PLEASE BE AWARE GYROCOMPASS MODE LOSES CALIBRATION WITHIN SECONDS OR A MINUTE OR TWO AFTER THE LAST CALIBRATION. (And does so under normal movement and turns by the user/holder of the device.)
