Eye care for people who forget to blink

The cat that reminds you to blink.

When you lock onto a screen, you stop blinking — and your eyes pay for it. Stare too long and a cat quietly creeps in from the corner. Blink, and it slips away.

blink, please

Screens are quietly drying out your eyes

The average person blinks ~20 times a minute. Staring at a screen? It drops below five. That's the gritty, tired-eye feeling by 4 PM.

Dry, gritty eyes

Deep focus tanks your blink rate without you ever noticing.

Reminders you ignore

"Take a break every 20 minutes" pop-ups get dismissed on reflex.

A nudge you can't resist

So instead of nagging, we send a cat. You'll actually look.

How it works

Three steps, running quietly in your menu bar.

01

It watches for blinks

Your webcam tracks blinks on-device. The longer you stare, the more a timer fills.

02

A cat creeps in

Pass your threshold (8s by default) and a cat peeks from the corner, inching closer.

03

Blink → it leaves

One blink and the cat slowly closes its eyes and slips off-screen. Relief.

Thoughtful by design

Gentle, not disruptiveIt never blacks out your screen. Just a soft visitor in the corner.

Live focus gaugeSee exactly how long it's been since your last blink.
Auto-pausePresenting or watching a movie? It steps out of the way.
Fully privateYour webcam video is processed on-device and never leaves your Mac.

Your camera, your business

Your webcam video is processed entirely on-device, in real time, then immediately discarded — never saved, never uploaded, never seen by anyone but you. No tracking. You don't need an account to use slow-blink; an optional sign-in is only for unlocking premium.

Bring the cat home

Install, allow the camera, and you're set. It lives quietly in your menu bar and Dock.
