Everything in your notch

Eight built-in modules that make the dead pixel zone the most useful part of your screen.

🎵

Now Playing

See what's playing, skip tracks, scrub the timeline. Works with Spotify, Apple Music, and any media app.

🔋

Battery

Glanceable charge level, time remaining, and charging status. Color-coded so you never miss low battery.

📅

Calendar

Upcoming events, countdowns, and one-click join for video calls. Syncs with your system calendars.

Weather

Current conditions, high/low, and location. All from Apple Weather — no API key needed.

🔔

Notifications

Surface incoming notifications in the notch. Tap to open or dismiss without breaking flow.

📷

Shelf

Drag files onto the notch to stash them temporarily. A clipboard tray that's always within reach.

🔊

System HUD

Volume and brightness changes appear in the notch instead of the default macOS overlay.

📡

Teleprompter

Paste a script and read it right below your camera. Perfect for video calls and recordings.

Extension SDK

Build your own modules

Write a JavaScript file, drop it in a folder, and your module appears in the notch. No Xcode, no compilation, no App Store review.
