PaceCheck
See your screen stamina before the afternoon crash.
A private, on-device eye check-in that turns screen load into Daily Eye Stamina — so you pace your workday instead of guessing when fatigue will hit.
The 3 PM Wall Is Real. You’ve Been Flying Blind.
Heavy screen days extract a toll you can feel but never quite measure. Dryness, afternoon focus fade, glare clashes, and heavy eyes shouldn't be the default price of doing deep work.
Without a reliable signal, you only notice fatigue after your productivity drops off a cliff. PaceCheck changes that by giving you a clear, quantitative handle on your digital ergonomics.
Three Steps to Total Screen Control
- The Quick Check-in: A secure, front-camera scan using advanced on-device computer vision. Oval framing, smart zoom, and instant alignment confirmation make it effortless.
- Your Daily Eye Stamina Score: Instantly translate a seconds-long check into a comprehensive stamina baseline backed by four core comfort pillars.
- The 30-Day Story: Track your pacing trajectory over time, correlate your breaks, and export professional PDF reports for your workflow or workspace setup.
Powered by the 5-Metric SSOT Engine
PaceCheck ditches vague wellness scores for a precise, multi-pillar digital ergonomics architecture:
- Hydration Feel: Monitors surface comfort and dryness indicators.
- Focus Endurance: Measures how long your attention holds steady under heavy screen loads.
- Room & Screen Balance: Evaluates how ambient workspace lighting clashes with your display.
- Visual Recovery: Tracks your eyes' ability to bounce back between intense sessions.
- Daily Eye Stamina: Your hero composite score for the day, keeping your screen energy in the green.
