GPXExport lets you export location information stored in your photos as GPX file. This file can be saved to iCloud Drive or exported into other applications.
Two options are currently available:
Save as Waypoints (wpt) or as trackpoints (trkpt). Certain apps only allow imports if multiple trackpoints are stored in one track. To do so a jiggle feature will place a second tack point aprox 1cm next to the original point.
The app has been tested with imports of 34000 photos containing 17000 locations. It might take a while but it was successful.
How many locations have you stored in your photos?
