Notice your eyes feeling uncomfortable after long hours on screens? It might be linked to how often or how fully you blink. Many people develop habits of blinking less frequently or not closing their lids completely (incomplete blinks) during focused activities, which can affect day-to-day eye comfort. BlinkBlink uses simple technology to help you build healthier blinking habits: • Real-time Blink Tracking: Leveraging advanced Vision Camera and Face Detection to monitor your blinking patterns throughout the day. • Blink Goal Reminders: Set personalized per-minute targets (e.g., 15-20 blinks). Get gentle alerts when you’re too focused on work or scrolling, helping you avoid long stretches with few blinks. • Incomplete Blink Alerts: Get instant reminders when partial blinking is detected, helping you become more aware of your blink pattern and practice fuller, more intentional blinks. Whether you’re an office worker, a student, or anyone spending hours on screens, BlinkBlink fits seamlessly into your routine as a tool to support healthier blinking habits. Make every blink count – support your eyes through better daily habits. Download BlinkBlink now, and give your eyes the care they need. ** BlinkBlink is a wellness reminder tool only. Not a medical device. Results may vary. Always consult an eye specialist for health concerns. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
