[Owncloud] iOS & Android Owncloud Client Synchronization feature

[Jean-Noel MARTINEAU]

Hello everyone,
We need synchronization between folders hosted on our owncloud and
mobile devices (iOS & Android)...
Some "WebDAV based App" exist with a sync feature in order to maintain
a local copy of such folders but we don't find a single editor with a
similar look & feel to add such  a feature in both iOS and Android
system...
Is there a existing project to include "sync" feature into a iOS and
Android Owncloud Client ?
Thanks ahead
