Sidekeys

Sidekeys is a Mac and iPhone/iPad app. The free Mac app connects to an iPhone or iPad over a USB-C cable (or Wi-Fi after pairing) and turns it into an extra display you can drag windows onto, with touch, two-finger scrolling, and on-screen keyboard typing. A deck of keys shows shortcuts for the app in front on your Mac, such as Xcode, Final Cut Pro, Figma, and VS Code, and switches to meeting controls during Zoom, Google Meet, Microsoft Teams, or Slack calls. It also shows each running Claude Code session as a card, letting you approve or deny permission requests with one tap. The page states it is built for iPhone Duo's inner screen and works on any iPhone or iPad, requires a Mac with Apple silicon running macOS 27 or later, and says screen and input data travel directly between your own devices with no analytics or tracking.
