Termphin

Termphin is an Android SSH client that keeps a remote shell alive through locked screens and dropped connections: a small open-source Rust agent pushed automatically over SSH holds the session open on the server and reattaches instantly on reconnect. It renders TUIs (htop, vim) cleanly via Flutter instead of a web view, and includes SFTP, an encrypted key vault, snippets, and port forwarding. Free, no ads, no in-app purchases.
