K2 Companion App is the mobile remote connection app for K2 by Alakazam Labs! K2 runs a small team of AI agents on your own computer. One handles research, one keeps your plans straight, one handles the errands and paperwork. They hand work to each other, keep going after you close the app, and message you on your phone when they need you.
Helmrig Shell
Read full descriptionHide full description
The terminal from your desk, now on iPhone and iPad. Helmrig Shell is a native terminal — btop, tmux, vim, true color, ligatures, full escape-sequence support, rendered natively. Not a web view, not a cut-down mobile shell. A real desktop terminal that feels like the one you already use. Your sessions run on your own Mac or server. The iPad or iPhone is just the window — so they never drop. Lock the screen, lose signal, switch to another app, come back hours later: every tab, every running process, your full scrollback, exactly where you left it. No reconnect dance, no lost output. Drop a file onto the terminal and it uploads to your machine, with the full path dropped straight into your command line. Hand a screenshot to a CLI tool, attach a file to a running command — it just works, as if the file were already there. Built on libghostty for the rendering you'd expect from a desktop terminal. Hardware keyboard shortcuts, split panes, tabs that name themselves after what's running. Designed for iPad first, not ported from somewhere else. Works anywhere over an end-to-end encrypted connection — at your desk, on the couch, or across the world. Not limited to your local network. Helmrig Shell requires a subscription to use. A free trial is available, after which continued access requires Helmrig Shell Pro at $8.99/month. Payment is charged to your Apple Account. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings. WHAT IT IS A window into your own machine. Your shell, your tools, your environment — running where they always have, now reachable from your iPad. WHAT IT NEEDS A Mac or Linux machine you control, running the Helmrig server. Setup takes one command. PRIVACY No third-party SDKs. No analytics. No crash reporting. Helmrig Shell servers never see terminal output.

Verdict
The clearest difference is update cadence: Helmrig Shell at every 2 weeks against K2 Companion's monthly. K2 Companion's advantage is iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
