Your Mac watches your blinks so your eyes stay healthy.

Blink Tracker monitors your blink rate in real time and sends gentle reminders when you forget to blink. Prevent dry eyes, eye strain, and headaches caused by screen time.

The Problem

When you focus on a screen, your blink rate drops from 15-20 blinks per minute to as low as 3-4. You don't notice it happening, but your eyes do.

Reduced blinking leads to:

  • Dry, irritated eyes
  • Eye strain and fatigue
  • Persistent headaches
  • Long-term corneal damage

How It Works

1

Sits in your menu bar

Blink Tracker runs quietly as a menu bar app. No dock icon, no windows in your way. Just a small eye icon showing your blink count.

2

Detects blinks in real time

Using your Mac's camera and Apple's Vision framework, Blink Tracker tracks your blink rate with on-device computer vision. Nothing is stored or sent anywhere.

3

Reminds you when you forget

Haven't blinked in a while? Blink Tracker sends a gentle notification. Choose your alert interval from 10 seconds to 60 seconds.

Privacy First

Blink Tracker is built with privacy as a core principle.

  • 100% on-device — All processing happens on your Mac. No data ever leaves your device.
  • No cloud, no servers — Zero network calls. The app never connects to the internet.
  • No accounts — No sign-up, no login required.
  • No tracking — No analytics, no telemetry, no third-party SDKs.
  • No ads — Ever.

Your camera feed is processed frame by frame in real time and immediately discarded. Nothing is recorded, stored, or transmitted.

Requirements

  • macOS 13 Ventura or later
  • A Mac with a camera (built-in FaceTime camera, USB webcam, or iPhone via Continuity Camera)
  • Camera permission (used solely for on-device blink detection)
