Horizon

Give your eyes a rest from long screen time.

Horizon is a macOS menu-bar app that gently takes over your screen for 20 seconds every 20 minutes — so your eyes can ease off, look into the distance, and refocus. Then it hands your screen right back.

First time opening Horizon

macOS adds one extra step the first time you open an app from outside the App Store. You only do this once.

  1. Open the downloaded Horizon.dmg, then drag the Horizon icon onto the Applications folder.
  2. Open your Applications folder and double-click Horizon. macOS will say it “could not verify” the app — click Done.
  3. Open the Apple menu → System Settings → Privacy & Security.
  4. Scroll down to the Security section. You’ll see that “Horizon was blocked” — click Open Anyway.
  5. Confirm with Touch ID or your password, then click Open Anyway once more.

That’s it — Horizon now lives in your menu bar (look for the eye icon), and you won’t see this prompt again.
