About Harlen
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. The information and recommendations provided by Harlen are intended for informational and wellness purposes only. Always consult a physician or other qualified healthcare professional, in addition to using Harlen, before making medical decisions or changing any treatment, health, fitness, or recovery plan. Never disregard, avoid, or delay seeking professional medical advice because of information provided by this app.
