SmoothSSH 🔒

SmoothSSH is a high-performance, gesture-driven SSH client for Android, built specifically for sysadmins who need speed, security, and a frictionless terminal experience on the move.

Forget clunky menus and dropped frames. SmoothSSH provides a smooth interface optimized for modern hardware like the Pixel 9 Pro XL, ensuring 60fps terminal scrolling and cryptographic handshakes that don't hang your UI.

✨ Key Features

• Multi-Session Swiping: Running maintenance across a cluster? Fluidly swipe left or right on the terminal canvas to instantly snap between active SSH sessions.
• The Transcript Engine: Stop fighting with mobile text selection. One tap dumps your entire live terminal buffer into a native, searchable text view—perfect for grabbing IP addresses or logs.
• Dynamic Control Row: A mobile-optimized accessory row that seamlessly swaps to vital sysadmin keys (SIGINT, EOF, SUSPEND) the moment you tap CTRL.
• Encrypted Vault: All connections, passwords, and private keys (PEM) are stored in a heavily encrypted local vault using AES-256.
• Biometric App Lock: Secure the entire application behind your device's native Fingerprint, Face ID, or PIN.
• Frictionless Workflow: Quick-add new Identities or Private Keys directly from the connection screen without losing your place.
• Volume Rocker Scaling: Instantly scale your terminal font size up or down using your phone's physical volume buttons.
• Portable Backups: Export your entire configuration as an encrypted .smoothvault file to migrate between devices securely.
