Slow Blink is a tiny menu bar companion that helps you remember to blink while you work
Slow Blink is a tiny menu bar companion that helps you remember to blink while you work. When you stare at the screen too long without blinking, a cute cat quietly peeks from the corner of your screen. Blink slowly, and it waves goodbye. That's it — no alarms, no guilt, just a gentle nudge from a small friend. HOW IT WORKS • Your Mac's camera watches your blinks — entirely on this Mac. Video is processed on-device and never stored, uploaded, or shared. Detection even works offline. • Set how long the cat waits before visiting (3–60 seconds of not blinking). • Automatic calibration learns your natural blink in seconds. MORE THAN A REMINDER • 20-20-20 eye breaks: every 20 minutes, the cat guides a 20-second break — the well-known optometrists' rule of thumb. • Stats that stay on your Mac: average blink interval, daily trends, 7/30-day averages, streaks. • Quests: unlock new cat friends free by building healthy habits — your first send-off, taking breaks, keeping a streak. • Premium: the Maine Coon comes with 6 moods and a special wall-peek entrance (one-time purchase, no subscription). PRIVACY FIRST • Camera video never leaves your Mac. No tracking, no ads, no third-party analytics SDK, no crash reporter. • The app reports one anonymous "started" count when it opens — the app version and nothing else. No account ID, no device ID, no installation ID, so two launches can't be tied to the same Mac. You can switch it off in Settings, and when it's off the app builds no request at all. • No account required — everything works without signing in. Optional sign-in only syncs purchases across your Macs. Slow Blink is not a medical device and does not provide medical advice. If you have eye discomfort or symptoms, please consult an eye-care professional.
