SMB Server turns your iPhone into an SMB (file sharing) server. From a Mac or Windows PC on the same Wi-Fi network, you can open your iPhone's Documents folder directly and copy, move, or delete files. No cables and no cloud required. [Great for] • Getting photos, documents, and music from your computer onto your iPhone without a cable • Quickly pulling files off your iPhone onto your computer • Moving files around at home without the cloud or an account • Handling files the familiar way, from Finder on Mac or File Explorer on Windows [Key Features] • File server supporting SMB2 (connect from Mac, Windows, Linux, and other SMB clients) • Start or stop the server with one tap • Bonjour support: appears automatically in the Network list in Mac Finder • Shows the IP address, port, and connection address (smb://...) you need, right on screen • Guest access, or set a password to restrict who can connect • Read-only mode (blocks writing and deleting from the computer) • Automatically start the server when the app launches • Keeps the screen from auto-locking while the server is running, so connections don't drop • View a log of connections, disconnections, and file operations • Shows the free space available in the shared folder • Open the same Documents folder from the Files app, too • Built-in guide for connecting, plus troubleshooting tips [How to Use] 1. Open the app, tap "Agree and Start", then tap "Start" (If asked to allow access to the local network, choose "Allow") 2. Enter the address shown on screen on your computer (YOUR_IP = the IP address shown in the app) • Mac: In Finder, choose Go, then Connect to Server, and enter smb://YOUR_IP:4455/Documents • Windows: Enter \\YOUR_IP@4455\Documents in the File Explorer address bar • Other SMB clients, such as Linux, can connect too 3. Sign in as a guest, or with the password you set Only this app's Documents folder is shared. The share name is fixed as "Documents". [Can't Connect?] • Make sure your iPhone and computer are on the same Wi-Fi network • Keep the app's screen open on your iPhone • Include the share name (/Documents) and the port number (4455) in the address • Mac Finder keeps a window in its failed state after a sign-in failure. Close the Finder window, then choose "Connect to Server" again. If it still won't connect, delete the old password in Keychain Access [Privacy] • Never connects to the internet. Works only within your local network (Wi-Fi) • Does not collect or transmit personal information, usage data, or file contents • Uses no third-party SDKs of any kind, including ads, analytics, or crash reporting • No account registration or sign-in required • Your Documents folder is shared only while the server is running. When stopped, it cannot be accessed from outside [Notes] • The server runs only while the app's screen is open. Closing the app disconnects all connections • The SMB port number is 4455 (the standard port 445 is not available due to iOS restrictions). You need to specify the port when connecting • With guest access, anyone on the same network can connect. Use it on a trusted network, or set a password
