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. COMPASS & GYROCOMPASS 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. FINDER, TRACKER & AR NAVIGATION 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. GPS, SPEEDOMETER & ALTIMETER 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. OFFLINE MAPS 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 STARS, SUN AND MOON & NAVIGATE BY STARS Track positions of stars, Sun and Moon with arc second precision – use them as a reference to calibrate compass for maximum accuracy. OPTICAL RANGEFINDER Measure distances to objects in real time with a rangefinder reticle similar to sniper sights. SEXTANT, ANGULAR CALCULATOR AND INCLINOMETER Find out heights of objects and distances to them – measure visually and calculate dimensions and distances. CAMERA Take pictures overlaid with all available GPS, positional and directional data.

Turn your iPhone or iPad into a practical field toolkit for camera measurement, maps, waypoints, compass work, and astronomical planning. RangeFinder brings the instruments you need into one focused app. Estimate a distance, inspect an angle, save a waypoint, measure a shape on the map, or plan around sunlight without breaking your workflow. CAMERA INSTRUMENTS • Estimate distance or height from an object of known size. • Measure distance with LiDAR on compatible devices. • Read heading, inclination, and roll, then capture an A–B angle. • Use Angle Survey with crisp, calibrated vector reticles. • Save camera, reticle, measurement, or full-screen compositions. MAPS THAT GO WITH YOU • Work with raster maps and detailed OSM vector maps up to zoom level 19. • Download supported map areas for use away from a connection. • Start with 512 MB of offline-map storage; save your first offline map to receive another 512 MB. • Search and inspect coordinates in Decimal Degrees, DMS, UTM, MGRS, Plus Codes, and GeoHash. WAYPOINTS WITH CONTEXT • Create waypoints on the map or from a photo’s GPS metadata. • Choose from 175 icons so every place is easy to recognize. • Add notes, photos, and voice messages. • Track selected waypoints on the map, compass, and live camera with their name and distance. MEASURE AND PLAN • Draw distances, polylines, angles, rectangles, polygons, areas, and circles directly on the map. • Use magnetic or true north, waypoint bearings, map rotation, and compass calibration. • Plan with sunrise, sunset, civil, nautical, and astronomical twilight, golden and blue hours, Moon phase, and planet positions—calculated on device. SAVE YOUR FIELDWORK Keep range observations, captures, waypoints, attachments, and map measurements organized for later. A safe migration assistant can bring compatible waypoints, media, and settings forward from the previous app. Camera frames and photo-location analysis are processed on your device. Availability and quality depend on device sensors, permissions, lighting, surface conditions, and location accuracy. Measurements are estimates and are not intended for safety-critical surveying or navigation.
