Sidekey turns your iPhone into a wireless keyboard, trackpad and shortcut pad for your own computer. Tap keys on your phone and they type on your Mac or Windows PC over your local Wi‑Fi — no extra hardware, no cables. NEW IN 1.1 • Made for iPhone Duo — unfold for a big keyboard on one side of the fold and a trackpad on the other, and swap them with one tap. Every mode gets its own big-screen layout. • Laptop keyboard mode — a full computer keyboard on the inner screen that matches the connected computer, Mac or Windows. • Landscape on any iPhone — keys, trackpad and sidebar rearrange themselves. FEATURES • Voice typing — dictate on your phone and send the text straight to your computer • Custom key designer — make your own keys, shortcuts and layouts • Shortcuts & combos — Cmd/Ctrl/Alt/Shift, function keys, media keys, and left/right-specific modifiers • Trackpad — use your phone as a touchpad with left and right buttons • Multiple computers — pair several and switch between them in one tap • Modes for every job — a shortcut deck, a trackpad, a full keyboard, and Codex Micro for Claude Code and Codex • Quick pairing — scan a QR code once; it reconnects automatically • Private by design — no account, no tracking, nothing sent to the developer HOW IT WORKS Sidekey works together with a small, free desktop helper you run on the computer you want to control. Put both devices on the same Wi‑Fi, scan a QR code once to pair, and you're connected. Pairing is secured with a token, and your keystrokes travel directly to your own computer — never through us.
