DropBox was awesome until I ran out of space. Now it is just annoying. Of course I could pay for more space, but i have found that my files have ended up in about 3 or 4 different fily syncing sites like Google drive, BitTorrent Sync, and others. Now there is an app that allows you to sync files across devices on your home network. Syncthing is compatible with all major desktop operating systems including Windows, Mac and Linux. There is now a mobile client version that is supported on Android. This app makes syncing up your photos and videos super easy. Head to the link below for the download.
Via Play Store
