Local shell — a real PTY on Android's own shell, with a full VT/xterm-256color emulator, scrollback, text selection, and a programmable key row.

Linux environments — installs Alpine, Debian, Ubuntu, Arch and others from the proot-distro catalogue: downloaded, checksum-verified, and extracted on device, then entered through proot. apt install works. So does gcc.

SSH — key or password auth, with credentials held in the Android Keystore.

Files — a browser over app storage, shared storage via SAF, and the guest filesystems, with privilege reported honestly rather than assumed.

Sessions — multiple tabs, groups, split view, snippets with placeholders, and quick commands.

Nothing here is mocked. There is no fake terminal output, no simulated filesystem, and no button that opens a placeholder dialog. When something cannot work on a device — no proot for the CPU, no root, no permission — the app says so and explains why.
