macOS
myTracks for macOS is the swiss-army knife for organizing your GPS tracks. They can be loaded from a broad range of devices and organized in a library comfortably.
Once imported you can drag & drop photo files (JPEG or RAW) to myTracks and they will be assigned to the GPS tracks automatically. The GPS information can be written to the EXIF and IPTC tags of the photo files (Geotagging).
GPS tracks can be exported as GPX, KML or KMZ files. You can use the exported files, e.g. with Google Earth.
iOS
myTracks turns your iPhone into a fully functional GPS logger. During recording, you can add waypoints to highlight important locations. The GPS tracks are stored on your iPhone and optionally in iCloud. There is no need to register or login to any network service.
You can start and stop individual GPS recordings or use the power-saving diary mode. Using this mode myTracks automatically creates a single track for each day with the most important locations.
The integrated Apple Watch app displays information about the current GPS recording. This includes the starting time, distance traveled, current, minimum and maximum elevation.
myTracks is available for iPhone and iPad on the App Store:
