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 - Full-screen break overlay with calming breathing animation - Posture break reminders — separate from eye breaks - Streak tracking: see how many breaks you actually complete - Weekly chart: visualize your eye care habits over time - Focus Hours: reminders only fire during your work hours - Rotating posture & stretch tips during every break - Works fully offline — no account, no data collection DESIGNED FOR DARK MODE Blink is built dark-first, with a refined near-black interface and a signature mint-green accent. It feels calm. It feels like it actually cares about your eyes — because it does. Light mode available too, or follow your system setting automatically. UNLOCK PRO — ONE TIME No subscription. No monthly fee. Pay once, own it forever. Blink Pro unlocks: - Custom intervals (any duration you want) - Full streak history and weekly analytics - Focus Hours scheduling - Posture break library (10+ rotating exercises) - Ambient sounds during breaks ONE-TIME PURCHASE. No tricks. YOUR PRIVACY Blink doesn't collect your data. Everything stays on your device. No analytics, no tracking, no account required. --- Recommended by optometrists: the 20-20-20 rule is endorsed by the American Optometric Association and eye health professionals worldwide. Computer Vision Syndrome (CVS) affects millions of screen workers — Blink helps you fight back. Download Blink and give your eyes the break they've been asking for.
