GeoReturn vs GuideDog Nav

Never lose your parked car, trailhead, campsite, or photography location again. GeoReturn is a precision GPS compass that guides you back to any saved spot with aviation‑inspired accuracy — even offline. Mark Your Location Save your exact position with one tap. GeoReturn reverse‑geocodes automatically, adds the address, and stores it in your waypoint history. Import from Photos Select any geotagged photo and GeoReturn extracts the GPS coordinates, creating a waypoint so you can return to that exact moment later. ADF‑Style Navigation A rotating compass rose shows your heading while a fixed arrow points to your destination. Bearing and distance update in real time for intuitive, aviation‑grade guidance. Waypoint History Every saved place includes a thumbnail, address, coordinates, and timestamp. Tap to navigate back or swipe to delete. Share Your Location Send a waypoint to anyone. They can open the link and follow the arrow straight to you. Customizable Settings Choose your GPS format, compass type (true or magnetic north), distance units, date/time format, and preferred navigation app. GeoReturn works offline once locations are saved. No account. No tracking. Your data stays on your device.
