Codeyzer Screen

Got a Mac and an Android tablet? You already own a second screen. Codeyzer Screen turns your tablet into a second display for your Mac: plug in the cable and your screen appears on the tablet. No developer mode, no USB debugging.

Free during the open test.

▶ JUST PLUG IN THE CABLE
• Plug-and-play USB (Android Open Accessory): approve the prompt on the tablet the first time, with no ADB to install
• Tunes itself to your tablet when it connects: stream and frame rate are set automatically
• Works wirelessly too: finds your Mac on the same Wi-Fi network by itself. Wi-Fi is fine for everyday work; for video and fast motion the cable is smoothest (with the Mac on Ethernet, Wi-Fi gets close)

▶ SHARP, SMOOTH PICTURE
• Up to 2.8K and 120 Hz with 10-bit color, if your tablet supports it (HDR10 or compatible HLG)
• Hardware-accelerated encoding that is easy on your Mac's processor

▶ USE YOUR MAC FROM THE TABLET
• By touch: scroll with your finger, pinch to zoom, long-press to right-click; three fingers to see all your windows (Mission Control)
• With a pen: the cursor follows the pen as it hovers; pressure and tilt (in apps that support them), eraser tip, side button for right-click, palm rejection
• With a keyboard: external and folio keyboards work one-to-one; the on-screen keyboard opens by itself when you tap a text field and shows your Mac's layout (ANSI/ISO/JIS)
• With a folio touchpad: Mac trackpad gestures — Spaces and Mission Control move with your fingers

▶ AND MORE
• Sound from the tablet's speakers: each tablet becomes its own sound output in macOS (a small audio driver is installed on the Mac once)
• Portrait mode: turn the tablet and your Mac's display turns with it
• More than one tablet: each one is a separate display, by cable or Wi-Fi
• Lid closed: the tablet becomes your main display, and you use it by touch
• Each tablet is recognized as its own display on your Mac: resolution, arrangement and HDR preference are kept for that tablet
• Away from home: through your own Tailscale account, all from inside the app (smoothness depends on the connection in between)

🔒 PRIVACY
Picture, sound and control input flow only between your Mac and your tablet. No account, no ads, no advertising ID — only anonymous usage statistics.
