SynoSync is a file synchronization tool crafted for iPhone and iPad, supporting Synology NAS, WebDAV, and SMB services. It is specifically designed to solve the long-standing issue where traditional sync software cannot flexibly integrate into the iOS "Files" app workflow. Simply log into your server, select a shared directory, and use the system file picker to specify a local target—allowing you to sync files to any authorized directory accessible by the Files app.
The app supports three sync modes: Server-to-Local, Local-to-Server, and Two-Way synchronization, while offering flexible conflict resolution strategies (Keep Newer, Keep Local, Keep Remote, or Keep Both). With support for extended foreground syncing and automatic background syncing, it is the perfect tool for long-term maintenance of note libraries, document repositories, research data, and project files.
