Blink - Screen Break Timer

Staring at screens all day? Your eyes are paying the price.

Blink is the most beautifully designed 20-20-20 eye break reminder for iPhone. Built for people who spend 6–10 hours a day in front of screens — developers, designers, writers, remote workers — Blink makes the doctor-recommended 20-20-20 rule effortless to follow.

THE 20-20-20 RULE
Every 20 minutes, look at something 20 feet away for 20 seconds. This simple habit, recommended by optometrists worldwide, dramatically reduces digital eye strain, dry eyes, headaches, and neck tension. The problem? Remembering to do it. That's what Blink is for.

HOW IT WORKS
Set your work interval. Blink runs quietly in the background. When it's time for a break, a full-screen overlay appears with a calming breathing animation and countdown — guiding you through the break so it actually helps. When you're done, it gets out of your way.

FEATURES
- Smart break reminders following the 20-20-20 rule
- Customizable work intervals: 10, 20, 30, 45, or 60 minutes
