Shellton

A fast, persistent SSH and Mosh terminal client for iPhone and iPad.

Shellton tries Mosh first on every connection. Mosh survives Wi-Fi handoffs, dead zones, and locked screens — your prompt is still there when you come back. If the server doesn’t have mosh-server installed, Shellton falls back to SSH automatically. No menus, no settings, just a connection that stays connected.
