Owlytics Healthcare uses machine-learning algorithms in combination with big data collected by smartphones and wearable sport and health devices. The resulting technology builds a predictive service layer as a mobile application to help manage family health and provide notifications based on medical-state prediction and healthcare-related events. Utilizing smart wearables, BandManage tracks individual physiological patterns, notifies care-givers about changes, and predicts health events. BandManage can detect and prevent falls, identify abnormal physiology, detect early dehydration signs, and detect flu symptoms.
