VisionGuard: Eye Health AI — App Store rankings

About this app

The developer's US App Store description, in full.

VisionGuard is the most comprehensive digital eye health app for iPhone. Using AI and your front camera, it monitors your blink rate, measures screen distance, and reminds you to take breaks — all processed 100% on-device for complete privacy. Pay once, use forever. WHY VISIONGUARD? You blink 15-20 times per minute normally, but only 5-7 times when staring at a screen. This leads to dry eyes, eye strain, and headaches. VisionGuard detects this in real-time and helps you build healthier screen habits. CORE FEATURES: • AI Blink Detection — Real-time blink rate monitoring using Apple's Vision framework. Get alerts when your blink rate drops below healthy levels. • Screen Distance Monitoring — Measures how far your phone is from your eyes using the front camera. Warns you when you're holding it too close. • Smart 20-20-20 Breaks — Intelligent break reminders based on the ophthalmologist-recommended 20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds. The timer only counts when you're actually looking at the screen. • Eye Health Score — A daily composite score based on your blink rate, screen distance, and break compliance. Track your eye health over time. • 6 Guided Eye Exercises — Focus shifting, palming, eye circles, near-far focus, figure eight, and rapid blinking exercises with animated guides. • Analytics Dashboard — Daily, weekly, and monthly charts showing blink rate trends, screen distance history, screen time, and health score progression. • Apple Health Integration — Sync your eye care break sessions to Apple Health as mindful sessions. • Home Screen Widget — See your eye health score and next break countdown at a glance. 100% PRIVATE: All face detection and eye tracking happens entirely on your iPhone. No images are stored, uploaded, or shared. No accounts, no analytics, no tracking. Zero data leaves your device. BASED ON SCIENCE: The 20-20-20 rule is recommended by the American Academy of Ophthalmology. Computer Vision Syndrome affects 50-90% of computer workers. VisionGuard brings clinical eye care recommendations to your pocket. SUPPORTED LANGUAGES: English, Chinese (Simplified & Traditional), Japanese, Korean, German, French, Spanish, Portuguese, Arabic One-time purchase. No subscriptions. No ads. No hidden fees.
