FAQ

Short answers, with links to the details.

Will it interrupt calls, games or presentations?

On Windows, no: a due break waits while a fullscreen app, presentation mode, a fullscreen game or video, or a call (another app using the microphone or camera) is active, and comes 2 minutes after. On Android it waits during calls, in landscape, and in apps you choose. iOS can't detect these. More on scheduling.

Is it free?

Yes. Downloading and using Blink Blink costs nothing. There's no account, no ads and no subscription. Install on Windows.

Which platforms can I use it on?

Windows 10 and 11 (64-bit) now. Android and iPhone versions are coming: they're written, but not yet tested on real phones, so there's no download for them yet.

Windows warns me when I open it

Blink Blink isn't code-signed yet, so Windows shows "Windows protected your PC". Choose More info, then Run anyway. More about the warning.

Does it track me?

No. No accounts, no analytics, no ads. Settings and history stay on your device. What's stored where.

Is it a medical device?

No. It's a comfort tool. It doesn't diagnose or treat any condition, and it won't prevent or reverse short-sightedness or the need for glasses. If you have eye pain, redness, sudden or ongoing blurry vision, flashes, or symptoms that don't improve, see an optometrist or ophthalmologist.

I've had eye surgery, or I have glaucoma

Turn off Squeeze step in Settings › Exercises, and check with your eye doctor. The squeeze becomes "Keep them closed."

I wear reading glasses

Some breaks suggest "Reading glasses? Slip them off for this one." Far looks are easier without them.

I don't have a window or a far view

Turn on No far view: eye breaks use eyes-closed rests instead of far looks.

Why 40 seconds and not 20?

20-second breaks alone showed no benefit in one trial, so eye breaks on a computer are 40 seconds. Phones default to 20 seconds. You can set 20 to 60 seconds. The research behind the timings.

Does it count my blinks or use the camera?

No. It doesn't use your camera and doesn't count blinks. On Windows it notices when another app is using the microphone or camera, only to hold breaks during calls.

Can I use it on a Mac or Linux?

Not yet. Windows is available now, and Android and iPhone are coming.
