Something else that has been making life easier lately is an update to the Olympus Image Share app. Previously you had to pick which images you wanted to download to your device over wifi and then hit upload, which was ok if you didn’t have too many images on the card but could get very laggy with a full card...
The update has an option in the setting to “view today’s photos” which once selected only shows the current 24hrs worth of images and makes it very quick and easy to do a batch upload of the days shooting...
Panasonic still leads the charge by offering the option of a batch download by today’s, two days or three days worth of images when you connect to the camera in transfer mode...
