The app lets athletes securely link with their coach, grant permission for wearable and health data access, and keep their latest metrics available to their coach’s dashboard. Once connected, athletes can view their coach link, wearable connection status, and recent data such as resting heart rate, sleep, and steps. Harlen is intentionally simple: the coaching workflow happens on the coach’s web dashboard, while the mobile app helps athletes connect their account, manage consent, sync wearable data, contact support, and control their account. Harlen is not a medical device and does not provide medical advice, diagnosis, treatment, or medical decision-making guidance.
