This is a great, reliable sync app with outstanding technical support. I've had FolderSync Pro for years and used it without any problems. Recently, I ran into my first issue, which had to do with authentication in setting up a folder pair to a cloud account. The support team was very responsive and helpful in solving the problem, which ultimately came from an unusual android device system config. Would highly recommend FolderSync for the utility, the versatility, and the terrific support.

Excellent app. I use it on vacation to backup my pictures and videos to my server at home. One feature request would make it perfect: allow setting the simultaneous transfers number per folder pair instead of globally. This will allow setting to 1 for optimum card to card transfer speed, or to a higher number for optimum Internet transfer speed. Thank you!

You have to set up an individual folder pair for every single folder that you want to sync. Why can't I just select a list of folders that I want to sync from my device to my nextcloud server? And what is with the stupid "left folder" versus "right folder"? Just use the standard terminology of source and destination instead of making it over complicated and unintuitive. This app is garbage.
