ZeroTier One for Android allows you to join ZeroTier virtual networks as VPN connections on your Android phone or tablet device. ZeroTier creates peer to peer virtual Ethernet networks that work anywhere. It's used as a faster alternative to VPNs, to provide a seamless hybrid or multi-site/multi-provider cloud backplane, for remote collaboration and distributed teams, and for Internet of Things (IoT) applications to provide direct end-to-end connectivity to specialized devices. See https://www.zerotier.com/ for more information and clients for other platforms including Linux, Macintosh, Windows, and BSD Unix.
