Every 20 minutes, look 20 feet away, for 20 seconds. Eye doctors call it the 20-20-20 rule. Eye Rest makes it effortless. A gentle vibration — on your iPhone or your Apple Watch — reminds you to rest your eyes through a screen-heavy day. No disruptive alarms. No guilt. Reminders are offers, never demands: snooze them, skip them, and the rhythm quietly continues. MADE TO BE WORTH IT • Tap Start once — reminders loop until you stop, restarting after each break • 12 vibration patterns you choose by feel, from a whisper to a desk-rattler • A 20-second break dial designed to be looked away from • Answer from the notification: Done, Snooze or Skip, without opening the app • A live countdown on the Lock Screen and in the Dynamic Island • Gentle statistics that encourage, never shame — no streaks to break • Working-hours and quiet-hours scheduling for office rhythms ON YOUR WRIST The Apple Watch companion carries the whole loop — the reminder, the break dial, the done — so a tap on the wrist is enough even when your iPhone is face-down in another room. Give "time to rest" and "rest is over" two different haptics, and choose both from the iPhone. BUILT TO ACTUALLY ARRIVE Reminders survive a reboot, a closed app, and a phone that has been in your pocket all morning. If notifications are switched off in a way that would silence them, Eye Rest says so plainly and takes you to the setting that fixes it, rather than counting down to a reminder that will never come. PRIVATE BY ARCHITECTURE Free. No ads, no subscription, no account, no analytics. Your settings and your break history never leave your device — there is no server to send them to. Export everything to a single file whenever you like, or delete all of it in one tap. Your eyes need the nudge forever — time blindness during focus is human hardware, not a habit to fix. Your eyes will thank you at five o'clock.
