Although Dropbox has an official Android application it’s a bare bones affair. Dropsync supercharges Dropbox syncing on your Android device with a pile of extra features and true two-way syncing.
Many people turn off synchronization features because they chew up battery life and the sync occurs too frequently. Dropsync gives you fine control over the syncing process allowing you to go so far as to specify how much battery life there needs to be for a sync to occur, how often to sync, whether the device is on Wi-Fi or 3G, and which folders on your SD card should be synced.
