The 20-20-20 rule is a simple habit recommended by optometrists to reduce eye strain:

Every 20 minutes, look at something 20 feet away for 20 seconds.

The problem is that most 20-20-20 apps are so annoying that I end up disabling them within a week.

They interrupt you mid-thought.

They popup during meetings.

They remind you even if you just stepped away from your desk.

So I built Blink .

Instead of blindly firing timers, Blink tries to understand context:

in flow? it waits for a natural pause

away from your desk? timer resets automatically

in a meeting? timer pauses

waiting for AI output?…
