Is Tempest for Android free?

Yes — the free plan covers SSH, Mosh, SFTP, FTP, S3, and WebDAV on Android and every other platform. Pro adds unlimited synced devices and the full protocol set.

Where do I download it?

Grab the APK from the download page — it installs directly, no store account needed.

Does it support SSH keys on Android?

Yes — import existing OpenSSH keys or generate a pair on the device; keys sync end-to-end encrypted if you want them on other devices too.

Can it stay connected in the background?

Continuous sessions are designed for exactly this: the session survives app switches and network changes, and Mosh handles roaming between Wi-Fi and cellular.

Does it work with tmux or screen on the server?

Yes — the terminal is fully VT-compliant, so tmux, screen, vim, and htop render properly, with touch scrolling and a modifier-key toolbar.

SSH client for Android

A real SSH client in your pocket

The 2 a.m. page shouldn't require opening a laptop. Tempest for Android is the same client you run on your desktop: full terminal, SFTP file manager, jump hosts, Mosh for cellular networks — with your entire host list already there, end-to-end encrypted.

Pick up a session your desktop started — and hand it back.
