Blink Rhythm Desktop Companion

An offline blink-and-break coach for people who stare at screens all day

Problem
Engineers, designers and researchers spend hours zooming into tiny details on screen, their blink rate drops without them noticing, and they only find out when their eyes become painfully dry. The poster is a 20-year computer-vision researcher and a victim himself, which shows how common and overlooked this occupational hazard is.
Solution
A fully offline desktop companion that tracks screen time via a local camera or a simple timer, nudges users to blink and take distance breaks on a healthy rhythm, and never uploads any imagery. It produces a personal eye-care report so the habit actually sticks.
Users
Heavy screen workers such as software engineers, designers, researchers and editors who spend 6+ hours a day in front of a display
MVP
Local-camera blink-rate estimation with a timer-only fallback; configurable blink and 20-20-20 break reminders; tray app with do-not-disturb windows; weekly eye-rhythm report; fully offline with no account
Revenue
One-time purchase ($15-25) or annual subscription, with team licensing and a cut from corporate wellness channels
Why now
Remote work has stretched screen time further and dry-eye syndrome is now a common occupational issue, while big-vendor health features are locked to their hardware ecosystems. On-device inference makes offline camera analysis viable on ordinary laptops, so a solo developer can ship a privacy-friendly tool fast
