## Description

90 seconds a day to keep your eyes fresh. Distance-corrected self-check, a 20-20-20 enforcer, and blue-light trends. Private by design. Not a medical device.

Squint is a 90-second daily wellness self-check for people who stare at screens all day. It's not a medical diagnostic tool — it's a habit-forming routine. Catch screen fatigue before it catches you.

WHAT SQUINT DOES
• A 90-second daily eye-care routine you can actually keep
• Distance-corrected vision self-check using the TrueDepth camera — the letters size themselves to the right distance, so the screen does the math for you
• A 20-20-20 enforcer that gently nudges you with a Live Activity: every 20 minutes, look 20 feet away for 20 seconds
• Blue-light exposure trends from your own screen-time patterns
• An optional symptom journal and a streak you'll want to keep

PRIVATE BY DESIGN
• No account, no sign-in
• No backend, no analytics, no third-party SDKs, no ads
• Your face is used only to measure distance — the camera image and face mesh are never saved and never leave your device
• Everything is stored on-device; Plus adds end-to-end encrypted iCloud sync

FOUR QUICK SELF-CHECKS
• Distance acuity (Sloan letters)
• Astigmatism fan dial
• Contrast sensitivity (grey-only, Pelli-Robson style)
• Near vision (Jaeger), with the phone held at a steady reading distance

Every result is framed against your own baseline and ends with "consider checking with an optometrist." Squint never diagnoses, treats, or names a condition.

MEMBERSHIP
• Free: one daily distance self-check
• Pro: all four self-checks, the 20-20-20 enforcer, blue-light trends, symptom journal, widgets, 30-day history
• Plus: Apple Watch quick-test, Family Sharing for up to 5, encrypted iCloud sync, CSV export, and an on-device weekly Ergonomics Plan

Squint is a wellness self-check, not a medical device. It does not diagnose, treat, or cure any condition. For any vision concern, consult an optometrist.
