Squint is a 90-second daily eye-care wellness routine for people who stare at screens all day: a distance-corrected vision self-check, a 20-20-20 enforcer, and blue-light trends — all on your device.
No account. No backend. No analytics, no ads, no third-party SDKs. Your face is used only to measure distance; the camera image and face mesh are never saved and never leave your device.
Squint is a wellness self-check. It does not diagnose, treat, or cure any condition. For any vision concern, consult an optometrist.
