PeekEarth vs Circulus Maximus WGS84

Explore the world in stunning 3D. PeekEarth turns your iPhone into a powerful geographic toolkit with a beautiful, minimalist interface. EXPLORE A 3D GLOBE Launch the app and see Earth as a realistic 3D globe. Pinch, rotate, and tilt to explore terrain from any angle. Switch between Standard, Satellite, Hybrid, and Dark map styles with a single tap. PIN LANDMARKS Tap anywhere on the map to drop a pin. Name it, save it, and come back to it anytime. Every landmark is stored locally on your device — no account required, no cloud, fully private. DRAW PATHS Plan routes by tapping points on the map. PeekEarth connects them with a path line and calculates the total distance in real time. Save your routes with custom names for future reference. MEASURE DISTANCES Need to know how far apart two points are? Drop measurement pins and get accurate great-circle distances instantly. Label each measurement so you remember what it represents — road width, river crossing, hiking segment. CALCULATE AREAS Tap three or more points to form a polygon and measure the enclosed area. Useful for estimating land size, park boundaries, or construction zones. IMPORT & EXPORT KML Open KML files directly from other apps like WeChat, email, or Files. PeekEarth parses Placemarks, LineStrings, Polygons, and gx:Track data. Export your own data as KML to share with Google Earth, Maps, or colleagues. WATERMARK CAMERA Capture geotagged photos with a built-in watermark camera. Each photo is stamped with the location name, coordinates, altitude, and timestamp — cropped to a clean 16:9 ratio. Save directly to your photo library. COMPASS Open a full-screen digital compass powered by your device magnetometer. See your heading in degrees and cardinal direction in real time. COORDINATE DISPLAY View live latitude, longitude, and altitude for the map center as you pan. Toggle the info panel on or off to keep your view clean. WEATHER AT A GLANCE Check current weather conditions for your map location with a quick tap. FULLY OFFLINE DATA All your landmarks, paths, measurements, and imported KML data are stored locally using Apple's SwiftData framework. Your data never leaves your device. DESIGNED FOR iOS Built entirely with SwiftUI and MapKit. Native 3D globe rendering, smooth animations, and a dark interface that looks sharp on every iPhone.

Trace the shortest path around Earth with professional WGS84 calculations. Circulus Maximus turns great-circle navigation into an interactive map, a detailed territory timeline, and precise instruments for bearings and route deviation. Built for sailors, pilots, radio amateurs — and every geo nerd who loves honest numbers. PLAN A WGS84 GEODESIC Choose any two points by address, coordinates, your current location, or directly on the map. See the ellipsoidal geodesic between them, inspect initial and final bearings, and explore the true continuation around the world. COMPARE ORTHODROME AND LOXODROME Display the shortest WGS84 route beside the rhumb line. Compare distance and constant course while both paths remain visible on the map. SEE EVERY TERRITORY ALONG THE WAY Follow countries and seas in chronological order along the route. Expand countries into available administrative levels to inspect regions and smaller areas. Country boundaries are bundled; optional sea and regional packages can be downloaded for deeper offline analysis. EXPLORE A CHOSEN DIRECTION Set a starting point and enter a bearing, turn the compass control, use the device compass, or follow your direction of movement. Circulus Maximus shows where that geodesic leads around the world. MEASURE ROUTE DEVIATION Use the Cross-Track instrument to calculate how far a selected or live GPS position lies left or right of course. Along-track distance, the abeam point, and remaining distance provide the complete geometric context. SOLVE A BEARING FIX Enter directed bearings from two or three known stations to estimate their forward intersection. Optional tolerances reveal the resulting uncertainty area. BUILT FOR PRECISE EXPLORATION Calculations use the WGS84 ellipsoid and GeographicLib algorithms rather than spherical shortcuts. Choose kilometers, nautical miles, or miles, and display coordinates as decimal degrees, degrees and decimal minutes, or degrees-minutes-seconds. Core calculations work offline. Address search and optional data-package downloads require an internet connection. Circulus Maximus is a calculation and exploration tool, not turn-by-turn navigation. Fair and transparent: every feature is free to try for 3 days. The trial simply ends — nothing is charged automatically. After that, the app becomes a view-only preview; full use requires the one-time Lifetime Unlock. One purchase, yours forever — no subscription, no recurring charges. The price is always shown before you buy.
