DropDuo is a pair of native apps that send files, folders, photos, links and text between your Mac and Android phone, directly over your local network. Pair once by scanning a QR code and approving it on your Mac. After that, the two devices reconnect on their own. • Right-click in Finder → Send with DropDuo, or use Android’s share sheet • Photos arrive as originals, and folders stay folders • Interrupted transfers resume and are integrity-checked • Encrypted end to end, no account, no cloud
