FolderSync user reviews :
I grabbed the free version to check syncing from Onedrive to local for my Obsidian mobile app. It works amazingly well, even with realtime sync if you need it. It has a multitude of options giving you great control over how you want to sync, what filters to apply, etc. Yes, the ads are annoying, but devs need to earn money for their hard work! I always buy these apps once I’m happy with them, which is exactly what I’ve done here. Great work!
amazing app that seems to have no competition for genuine synchronization of folders locally and remotely. would recommend highly did everything I need to do to do on the free version but still paid them because it’s such a terrific app great customer service and communication. glad to support companies like this that are making truly useful powerful and unique apps
After many years of usage, I’ve had to downgrade the rating of this app. In the last few android versions (now on Android 12), my scheduled daily sync seems to stop working after a few weeks. I’m not sure the cause – I suspect either updates to the app from Play store; restarting my mobile; or some aggressive Android app management. Unfortunately I can no longer rely on this app to do my daily syncing, as I receive no notification if my daily sync schedule has stopped. Real shame!
Works great with one exception. If it has a permissions error, it pauses for several seconds turning what would be a 1 minute sync into one requiring several days.
Syncs a directory on your phone with a cloud storage. Simple as that! Exactly what I was looking for to backup my pics and documents.
Great app! However I have one little suggestion. I am using the instant sync feature to move my photos to my personal cloud and then it is set to delete the copy from my phone. Everything is working perfectly…except…it does it too fast! Sometimes I take a pic to send to someone but before I can send it…it’s gone! Is there a way to hold off 30 seconds or so before doing the instant sync?
This is the amazing app to sync folder to cloud or local, many useful option available that we need actually, thanks so much developer
A very good SMB1 backup app. Configuration is not easy to understand while not intuitive. And has two major cons for me: I can not see any progress in action, when I try to sync and nothing happened, the play symbol / “Sync” appears after a few minutes again, but no info if ok or not. So I have to tick on the minuscular calender symbol with the last sync date and time, but can almost never hit it, only after 5-10 tries, because it is soo damn small. And when I create a new sync pair, I expect to select first the source and second the target, not invers. That’s not logic. Would be nice to have a sound selection or app-fixed loud beep for information when sync is over. And a “Compare before sync” whith viewable logfile would be nice.
Perfect app. Does what it has to. Tested with Dropbox and Google drive.
