SuperDuper Terminal

Nobody develops from a phone. What people actually do is check on a long-running job, restart a service, or answer a prompt from an agent that is still waiting.

SuperDuper Terminal is built for that shape of use. A full SSH terminal with a real PTY — colours, cursor keys, everything a shell expects — and tmux sessions by default, which is the decision the rest follows from. Close the app, walk into a tunnel, lose the signal: reconnect and you are exactly where you left off. On a phone the connection is not an edge case, it is the normal condition.

Multiple servers and live sessions from a tab strip. A keyboard row with the keys iOS hides from a command line: Esc, Ctrl, Tab, arrows, pipe, slash. Port forwarding when a remote port needs to be local.

Keys never leave the phone

Ed25519, ECDSA and RSA keys are generated on the device and stored in the Keychain behind Face ID. Nothing is uploaded, so there is no server that could be asked for them.

Free.
