Heart Rate Variability (HRV) Biofeedback is a technique that can directly affect physiological and psychological factors through deep breathing exercises and is an ideal strategy to help us self-regulate and better cope with stressful situations​ Practically speaking, HRV Biofeedback consists of providing an individual with real-time feedback on instantaneous heart rate and respiration changes while being instructed to breathe at low frequencies You can learn more about the psychological and physiological benefits of deep breathing and HRV Biofeedback, at HRV4Biofeedback.com HOW CAN I BENEFIT FROM BIOFEEDBACK? Life can be demanding, from both a physical and psychological point of view ​Our health and performance can be affected by how we are able to effectively cope with stressful situations and deal with anxiety, or in broader terms, our ability to emotionally self-regulate is key The goal of HRV Biofeedback is to improve self-regulation, therefore impacting positively our health and performance LEARN MORE: - App features: https://www.hrv4biofeedback.com/faq.html - An introduction to biofeedback: https://www.hrv4biofeedback.com/blog/a-primer-on-heart-rate-variability-biofeedback - How to use the camera measurement: https://www.hrv4biofeedback.com/blog/guidelines-and-best-practices-for-camera-based-measurements Supported devices for the camera measurement: iPhones 8 and onwards HRV4Biofeedback requires to register an account with your email address, so that your data can be backed up safely and retrieved in case anything happens (app issue, changing phone, etc.) The validation of the camera-based heart rate measurement is available here: https://www.researchgate.net/publication/315059917_Comparison_of_Heart_Rate_Variability_Recording_With_Smart_Phone_Photoplethysmographic_Polar_H7_Chest_Strap_and_Electrocardiogram_Methods

FatigueSense helps you understand your energy and pace your days, so you can do more of what matters with less risk of crashing. Built by digital health researchers, it links data from your wearable with quick daily check-ins to show how your activity, recovery, and fatigue relate over time. It is designed with and for people living with persistent fatigue — ME/CFS, long COVID, fibromyalgia, cancer-related fatigue, and other long-term conditions. What you can do • See your daily energy budget and how much you have left • Get an early signal when you may be approaching post-exertional malaise (PEM) • Track strain, recovery, HRV, resting heart rate, and sleep in one place • Plan activities that fit within your personal energy envelope • Log crashes and check-ins so the app learns your individual patterns • Connect a wearable, or use manual daily entry — no device required Works with your wearable Apple Watch, Oura, Garmin, WHOOP, Polar, Withings, Fitbit, and more. An honest, research-led approach FatigueSense is assistive and statistical. Its outputs complement your own judgment — they do not diagnose or treat any condition, and they are not validated for every diagnosis. Fatigue is not one thing, and the app does not assume all conditions behave the same way. You know your body best. FatigueSense is a wellness and self-management app. It is not a medical device and is not intended to diagnose, treat, cure or prevent any disease. Energy estimates, pacing guidance and symptom risk indicators are informational only and are not medical advice. Always speak to a qualified healthcare professional about your health, and before changing anything about your treatment or care.
