Sidekey turns your iPhone into a customizable wireless keyboard 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. Design the keyboard you actually want: add keys, build shortcuts (including combos like Cmd/Ctrl, and left/right modifiers), arrange them on a grid, and switch between layers and modes. Keep your most-used shortcuts one tap away. 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. FEATURES • 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 • Multiple layers & modes — flip between a full keyboard, a shortcut deck, a trackpad, and more • Trackpad mode — use your phone as a touchpad with left/right buttons • Voice typing — dictate with the system keyboard and send the text to your computer • Quick pairing — scan a QR code; reconnects automatically afterward • Works with Mac and Windows • Private by design — no account, no tracking, nothing sent to the developer REQUIRES THE FREE DESKTOP HELPER Sidekey needs the free Sidekey helper running on your Mac or Windows computer.
