MissionNAV vs GEO Calc

MissionNAV is a professional field-navigation app for hiking, search and rescue, hunting, surveying reference, emergency preparedness, geocaching, and outdoor operations. Navigate with accurate GPS position data and view your location in MGRS, USNG, UTM, OSNG, latitude/longitude decimal degrees, degrees-minutes-seconds, and degrees-decimal-minutes. Convert coordinates, copy or share them, create waypoints, and open locations on the map. Use the navigation compass to track bearing and distance to a selected waypoint. View target direction, current heading, speed, altitude, GPS accuracy, course, and estimated travel information. Optional haptic feedback helps indicate when you are aligned with your target. Create waypoints from your current GPS position, manual coordinate entry, map center, long-press map placement, or distance-and-bearing projection. Rename, edit, favorite, duplicate, reorder, organize, and delete waypoints. Group locations into overlays such as Home, Hiking, Emergency, Survey, or Mission, with visibility controls, custom icons, and colors. The Field Map provides standard, satellite, and hybrid map styles, user location tracking, waypoint markers, a fixed center targeting reticle, coordinate display, and map-based waypoint creation. Measure distance and bearing between locations and quickly purge all saved waypoints when needed. Import and export waypoint data using GPX, KML, CSV, and MissionNAV JSON backups. Share individual waypoints or your complete waypoint dataset using the native iOS share sheet, including AirDrop, Messages, Mail, Files, and iCloud Drive. Customize the Dashboard and Navigate screens with reorderable data panels, adjustable font sizes, unit preferences, and multiple display presets. Choose metric, US/Imperial, or both units for distance, speed, and altitude. Personalize the experience with Tactical Green, Amber Night, Ocean Blue, High Contrast, and daylight-friendly display options. MissionNAV stores waypoint data locally and core navigation features work without an account or subscription. GPS-dependent readings are clearly identified and are never fabricated when unavailable.

GEO Calc : Coordinates is a WGS84 field calculator for surveyors, engineers, and outdoor professionals. Convert coordinates, compute geodesic distance and bearing, measure on a map, and manage waypoints—on iPhone and iPad. COORDINATE CONVERTER Convert Decimal Degrees, DDM, DMS, UTM, MGRS, USNG, and Plus Codes. Auto-detect format. Copy results in one tap. DISTANCE & BEARING Vincenty geodesic distance and forward azimuth on the WGS84 ellipsoid—not flat-map shortcuts. Direct geodesic calculator (Pro). MAP & MEASURE OpenStreetMap tiles with path and polygon measure on the ellipsoid. Optional satellite layer (Pro). Go-to coordinate. Live GPS (Pro). FIELD NAVIGATOR (PRO) Walk to a coordinate with a live compass arrow and arrival alert. WAYPOINTS & GPX Save waypoints on your device. Export GPX 1.1. Import GPX waypoints (Pro). Free tier: up to 20 waypoints. UNITS & LANGUAGES Metric, imperial, or nautical. Twelve languages. Dark theme for outdoor readability. IN-APP PURCHASES Free to download with ads. GEO Calc Pro is a one-time, non-consumable in-app purchase—no subscription. Pro unlocks direct geodesic calculator, live GPS, field navigator, satellite map layer, GPX import, and unlimited waypoints. Restore purchases anytime from Settings or the Pro screen. INTERNET & LOCATION Map tiles load over the internet from OpenStreetMap. Live GPS and field navigation use device location when you allow it. Not for certified legal surveying. Verify critical measurements with professional methods.
