Unlike some other apps that sort of work or are finicky, PhotoSync works nice and smooth, no glitches, no stutters. Period.
There is a built in tutorial that guides you through how to transfer photos from your device to your computer, another device, or many different sharing sites. Folow the instructions and it works.
Luckily the default is to transfer full-sized photos but you can chose to downsize if you want.
I read on some forums about using it and there were all kinds of cautions: be sure to set this and that. I was apprehensive but the developers must have been listening because all those cautions were addressed right in Preferences and set as defaults.
I chose not to use iCloud so this app is invaluable.
Im impressed at how easily this apps does what it says.
