Did not work after Android update to 4.2, but the problem was fixed less than one day after the first reports on the issue. UPDATE: support is still as great as the app itself. Version 184.108.40.206 had a bug that caused it to ignore remote file modifications. It was fixed in a matter of hours after reporting it.
Sync over mobile data start with a big delay, like 30 seconds; latest updates didn't fixed that.
No response to support msgs Folder Sync stopped working for me and there has been no response from the developer in spite of me sending multiple emails
Very useful I use it to back up photos, downloadables (and whatsapp database before). Easy to set up folder pairs. I only try one way transfer so far. Not sure about the performance of two way sync.
Fantastic Sync App Once you learn how to use it this app is extremely effective in protecting your data. The latest updates have improved it even more. Works flawlessly - this is a must-have app.
Android 6 - fixed! Love this app and was upset when it no longer worked with external SD cards and android 6.0. Happy to say its working great now. I am noticing a weird issue of syncs automatically cancelling after 22minutes under 6.0 not sure what's up with this.
Bugfix: minor bugfixes.
Bugfix: fix for external SD card on Marshmallow.
Bugfix: fixed issue with checsum for files not being used properly.
Bugfix: other minor bugfixes.
