## Description

ReadiOne by Fatigue Science is a powerful Chrome extension designed to provide users with personalized fatigue alerts and alertness predictions based on sleep data. By syncing sleep information from the Fatigue Science ReadiBand or Fitbit devices, it uses a proprietary biomathematical model developed over 25 years of research to quantify and forecast the impact of sleep patterns on your cognitive performance and reaction times throughout the day.

Each morning, ReadiOne calculates your "ReadiScore," giving you hourly insights into your alertness levels for the subsequent 18 hours. The extension visually displays periods where you are predicted to perform at your best or face heightened fatigue risk. It also sends timely alerts before your fatigue reaches critical levels, helping users take proactive steps to maintain safety and effectiveness. Tailored primarily for users of the Readi enterprise fatigue management platform, ReadiOne ensures you stay informed and ready to tackle your day with optimal performance.
