Syncthing is awesome, I don&#x27;t understand why some people still use bittorrent sync. If you use ownCloud only for file syncing you&#x27;d also be better off using Syncthing instead. The developer is also a super nice guy, answering all bug and performance reports on github.<p>Regarding contact &amp; calendar syncing, I just wish more apps could just use files instead of always setting a new server and reinventing the wheel to sync data. I still have not found a good way to export my calcurse calendar to my Android phone via files only.
