Coordinate Converter
Read full descriptionHide full description
Read coordinates from your camera or an imported image, use your live location or select a point on the map, and convert between reference systems. Keep your results ready for the next step. CoordCap is free to download. Manual conversions, the built-in WGS 84 / UTM workflow, and Auto UTM on the map are free. CoordCap PRO is an optional, one-time in-app purchase that unlocks other map targets, plus capture and saving with additional transformations. No subscription. INCLUDED FOR FREE - Enter coordinates manually and convert them using the built-in WGS 84 / UTM workflow or transformations you add. - Read original coordinates with your camera or from imported images. - Convert between WGS 84 latitude/longitude and UTM using the built-in workflow. - Capture, review, save, and export individual coordinates and coordinate lists using the built-in WGS 84 / UTM workflow. - View, copy, and save map coordinates with Auto UTM. Use your live location or select a point with the crosshair; the UTM zone and hemisphere update automatically. - Copy and share manual conversion results. REQUIRES COORDCAP PRO - View, copy, and save map coordinates using any target other than Auto UTM, in both Live and Target modes. - View converted coordinates from your camera or imported images using transformations you add beyond the built-in WGS 84 / UTM workflow. - Capture and review coordinate lists using those additional transformations. - Save individual results using additional transformations, including results entered manually. - Save and export captured coordinate lists using additional transformations. Manual conversion with an added transformation is free. Using that transformation to view converted map coordinates, for converted camera or image capture, or to save results requires PRO. Auto UTM on the map stays free, including copying and saving. The built-in WGS 84 / UTM workflow also stays free, including capture, saving, and export. REVIEW BEFORE YOU USE Check captured readings, correct coordinates, and choose which rows to include before exporting. Coordinate recognition can make mistakes, so always review results against your source.

Point your camera at the horizon and your waypoints appear floating over the real world — near ones large and close, distant ones small and faded. No map to download. No data connection. No account. Just your camera, GPS and compass, working when nothing else does. Off-Grid GPS answers one question: which way, and how far? It is not a mapping app and it will not plan a route for you. It is the modern equivalent of a hand-held GPS and a compass - a bearing, a distance and a running ETA to every point you care about, updated every second. THE AR VIEW Point your phone and your saved waypoints hover over the live camera feed, placed by compass bearing and GPS. Nearby points appear large and bright; distant ones shrink and fade. No headset, no special hardware. THE COLOUR CUE Your waypoint list is alive. Each row shades toward green as you close in and toward red as you drift away. Across the whole list, at a glance, you can see which destinations you are approaching and which you are leaving behind - without reading a single number. EVERYTHING ELSE - Live distance, bearing and ETA range to every saved location - Tap any waypoint for degrees to turn, closing speed and absolute bearing - GPS speed, course, elevation and accuracy, with a colour-coded accuracy bar - Add waypoints by map search, or drop and drag pins - Metric, imperial or nautical units - Fully dark interface - Works in flight mode WHO USES IT Hikers heading off trail. Sailors and kayakers crossing open water. Drivers on remote desert roads. Geocachers, hunters and anglers. Radio amateurs taking bearings to distant towers. Anyone who needs a direction and a distance when the map runs out. FREE, WITH NO CATCH No ads. No nags. No subscription. No account. No tracking. Your waypoints are stored on your device and never leave it. I wrote the first version of Off-Grid GPS in 2009 because I needed it myself. It has been free ever since.
