Screen Distance – Eye Health

Screen Distance helps you and your children keep a healthy distance from the screen. Using the front TrueDepth camera, it measures how far your face is from your device in real time and gently warns you whenever you lean in too close.

Holding a phone too close is a major cause of eye strain and is linked to worsening short-sightedness (myopia), especially in children. Screen Distance gives you a simple, always-on reminder to back off.

REAL-TIME DISTANCE
• See exactly how many centimeters your face is from the screen
• A clear ring turns green at a healthy distance and red when you are too close
• Set your own alert threshold from 20 to 50 cm

GENTLE ALERTS
• A soft vibration nudges you when you lean in too close
• 20-20-20 break reminders: every 20 minutes, look 20 feet away for 20 seconds

EYE-CARE INSIGHTS
• Daily and weekly charts of your average distance and alerts
• Watch your screen habits improve over time

COMPLETELY PRIVATE
• The camera is used only to measure distance
• No photo or video is ever recorded, saved, or sent anywhere
• Everything happens on-device, fully offline

REQUIREMENTS
An iPhone or iPad with a TrueDepth front camera, iOS 17 or later.
