Sync crash on iOS

It seems that my problem has been reported previously. But the solution is not OK for me since I work a lot on my iPhone in a train and don’t want to erase all my job and then resync !
It is a real pain to be faced with such a recurrent problem ! Sync MUST be robust !
Is there any way to use other service than dropbox ?

The sync crash that was reported in November/December was fixed in an update to iOS Scrivener. If you have the latest versions of both Dropbox and iOS Scrivener and are still seeing crashes, then you are seeing a new problem. Please start a support ticket.

If you’d rather not use Dropbox, you can use iTunes to transfer files between your desktop and your iOS device.
