BlinkTide: Eyes in Rhythm

Eyes in rhythm.
Private focus on your Mac.

BlinkTide uses your Mac’s camera to observe and analyse your recent blink rhythm locally. It lives quietly in your menu bar, offers a gentle visual cue when you need it, and can remind you to look away.

01 / CAMERA-BASED ANALYSIS

Your recent rhythm, at a glance.

Using your Mac’s camera locally, BlinkTide analyses blinks from the last 60 seconds. It is a live session signal, not a health measurement or a record of your day.

02 / BLINK REMINDERS

A visual cue based on your blinks.

When camera-based analysis finds that you have not blinked for your chosen interval, a gentle cue can appear. Blink to clear it. Add optional background dimming; reminders stay quiet when you step away.

03 / SCREEN BREAKS

Make room for a pause.

Enable a separate cue to look away from the screen. Choose an interval that suits your routine; it is off until you turn it on.

04 / OPTIONAL PREVIEW

See the signal, not your history.

Open the optional local Preview to check your setup while BlinkTide is running. Lighting, glasses and head position can affect the estimate.
