Limeo is a wearable-connected fatigue risk awareness system for high-intensity sports users. It helps people sense rising physical risk before fatigue becomes fully obvious, using a smart wristband for real-time alerts and a mobile app with built-in AI for daily readiness, workout tracking, recovery guidance, and post-workout insights. By translating invisible body strain into understandable feedback, Limeo supports safer training, better recovery, and earlier intervention before fatigue turns into injury.
