Terminalko is a fast, focused SSH terminal for iPhone and iPad. Connect to your VPS, Raspberry Pi or any Linux box, run a real shell, get work done without a laptop. Add a server and you are at a prompt in a minute. [ A real terminal ] A true xterm-256color PTY with ANSI colors, scrollback and a keyboard aware layout. htop, vim and tmux behave exactly like they should. [ SSH, Mosh and Telnet ] SSH with password or key auth, jump hosts through a bastion in one hop. Mosh survives Wi-Fi to cellular switches, IP changes and long sleeps. Your prompt is still there hours later. Telnet for legacy gear: switches, routers, the odd BBS. [ Edit files over SFTP ] Open the config, fix the wrong line, save it back in place. Sizes, permissions and dates on every row. Upload, download, rename, delete, new folder. [ SSH keys, Secure Enclave included ] Generate an Ed25519 key on device and copy its authorized_keys line, ready to deploy. Paste an existing OpenSSH key. Or make one in the Secure Enclave, where the private half cannot leave the chip. A different key per server. Secrets live in the iOS Keychain. [ Dropped connections reconnect ] Connection Keeper retries a dropped session with a visible overlay and a cancel button. Lock the phone, tmux keeps working server side, the session re-attaches when you return. [ Themes and fonts ] Fifteen built in themes, plus an editor for your own: all 16 ANSI slots, text, background, cursor and selection, live preview. Twenty monospace faces bundled, nothing to download. [ Maximum Privacy and Security ] No tracking, no ads, no spying. Face ID, Touch ID, Optic ID or your passcode, with a grace period you choose, and masks it in the app switcher. No analytics, no ads, no accounts, no telemetry. The app talks to your servers and to nothing else. [ Our mission ] Make the best terminal and SFTP app there is. Every version came from someone saying what was missing. If something is missing for you, say so. [ Requirements ] iOS or iPadOS 17 or later. Built for developers, sysadmins and homelab tinkerers. Check a server from the couch, SSH into a Pi from bed, restart a service from the train. Terms of Use: https://terminalko.com/terms/

Terminalko's advantage is update cadence (every 4 days vs every 7 months) and chart position (#31 vs unranked). On ads, device support and iOS requirement there is nothing between them.
