SynoSync vs NASLink

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.

NASLink is a secure SMB file manager that connects your phone to your NAS, Windows PC, or Mac from anywhere — over your own Tailscale network, with no port forwarding and no cloud upload. • BROWSE & PLAY INSTANTLY Navigate your SMB2/3 shares and preview photos, videos, music, and documents right on your phone. No need to sit down at a PC just to find one file. • FULL FILE MANAGEMENT Copy, move, rename, delete, and download files and folders. Multi-select and recursive folder transfers let you organize entire libraries in a few taps. • TRANSFER BOTH WAYS Move photos, videos, audio, and documents between your phone's local storage and your SMB shares — back up your camera roll to the NAS, or take files with you. • SHARE FOLDERS SAFELY Send expiring folder invitation links. Links never contain your SMB username or password, and recipients need permission on both your Tailnet and the SMB server. • PRIVATE BY DESIGN SMB credentials are stored in your device's secure storage. NASLink never sends your server details or file contents to its own servers — traffic flows only between your Tailscale network and the SMB server you choose.
