ReadiOne by Fatigue Science is a lifestyle application available on iPhone. It aims to help users manage their fatigue levels by analyzing their sleep patterns. By utilizing a proprietary biomathematical model, ReadiOne quantifies and predicts the impact of sleep on daily performance, crucial for individuals in demanding professions or sports.

Users can sync their sleep data from devices like the Fatigue Science ReadiBand or Fitbit to receive a personalized risk assessment known as "ReadiScore" for the upcoming 18 hours. This feature enables users to visualize their peak and low performance periods throughout the day. Additionally, the app allows users to track their readiness improvements over time and receive alerts to prevent critical fatigue levels. Developed with 25 years of sleep research from the US Army Research Lab, ReadiOne offers validated algorithms exclusively through Fatigue Science.
