Your iPhone is your Mac's wireless trackpad and keyboard.
Airothy turns any iPhone on your local network into a secure, low-latency input device for your Mac. Multi-touch gestures, full keyboard, Mission Control, media keys — all without leaving your couch.
Multi-touch trackpad
One-finger pointer, two-finger scroll and pinch-to-zoom, three-finger Mission Control and Space navigation. Tuned for the real macOS gesture vocabulary.
Full Magic Keyboard
Hold-to-use modifiers, client-side key repeat, Mac-generation-aware function row with brightness, media, mute, and volume. Or use the iOS keyboard with a Cmd / Opt / Ctrl / Shift accessory bar.
Authenticated by design
Curve25519 key exchange, HMAC-signed command envelopes, monotonic sequence numbers, and explicit Mac-owner pairing. No cloud, no third-party servers, no telemetry.
How it works
Three steps, ~60 seconds the first time.
Install on Mac
Download the notarized `.dmg`, drag to Applications, grant Accessibility permission in System Settings.
Pair your iPhone
Open Airothy on iPhone. Scan the QR or enter the 6-digit code shown on the Mac. Trusted once, paired forever.
Control your Mac
Use the trackpad surface for gestures, or the full-screen Magic Keyboard for typing. Auto-locks when you put the iPhone down.
Privacy and security
- Local network only. The iPhone and Mac talk peer-to-peer over Bonjour and TCP. Nothing transits the public internet.
- No accounts. No sign-up. No login. No third-party servers. No analytics. No telemetry.
- Open protocol, signed code. The macOS app is Developer ID signed, notarized by Apple, and auto-updates via Sparkle with EdDSA-verified release signatures.
- One controller at a time. The Mac will not accept commands from more than one paired iPhone simultaneously; takeover requires explicit Mac-side approval.
