20-20-20 eye break timer for Mac.
Work for 20 minutes, look away for 20 seconds, and repeat. Use this timer now; install Peeku Presence Coach when you want the habit in your Mac menu bar with private local presence signals.
Free. No account. The browser timer stays on this page; the Mac app keeps reminders in the menu bar.
Break counted. If this helped once, Peeku can keep the same eye-rest rhythm in your Mac menu bar without leaving a browser tab open.
Install the free Mac appPeeku Presence Coach is the Mac App Store build: eye-rest prompts, walk reminders, local presence signals, and no account. The full walk-away lock is separate because the App Store sandbox cannot run the automatic lock command.
Why this page exists
A small tool beats a cold pitch.
The 20-20-20 rule is simple enough to explain and hard enough to remember during real work. A timer is useful immediately, which makes it a better introduction than an ad. Peeku is the next step: the same habit, sitting quietly in the Mac menu bar.
The American Optometric Association describes the rule as a way to help alleviate digital eyestrain. The American Academy of Ophthalmology also recommends looking away from the screen, blinking, adjusting lighting, and keeping enough distance from the display. This page is a reminder tool, not medical advice.
- Timer first. Use the browser tool before installing anything. No account, no email gate.
- Menu bar next. Peeku keeps the reminder visible while you work across apps, not just in this tab.
- Private signals. The Mac app uses local presence signals. No cloud face data, no presence account.
- Honest upgrade path. App Store coaching is free; full automatic locking uses the direct Mac build.
Keep the habit
Move this from a browser tab to your Mac menu bar.
Peeku Presence Coach adds private eye-rest and walk reminders, Desk Health, and local presence signals. If one break helps, an honest App Store review after trying the app helps other Mac users find it.
