Empirical works with all Apple Watch / iwatch health sensors: heart rate monitor (pulse), ECG (electro cardiogram), HRV, blood oxygen saturation, activity, deep sleep, REM sleep, sleep stages, afib history, vo2max (cardio fitness), heart rate recovery (cardio recovery), temperature, depression and anxiety risk, sleep apnea alerts, breathing disturbances, and more.
Metrics summarizes 40+ biomarkers into one health score, including resting heart rate, heart rate recovery (cardio recovery), ECGs (electro cardiograms), irregular rhythm notifications, heart attack risk (based on the American College of Cardiology's heart attack risk calculator), HDL cholesterol, LDL cholesterol, ApoB, LP(a), sleep duration, sleep onset, deep sleep, REM sleep, sleep apnea risk, breathing disturbances, oxygen saturation (SpO2), respiratory rate, and VO2 Max (cardio fitness), HRV, temperature, depression, and anxiety.
We summarize all Apple Watch vitals--the heart rate monitor, sleep, VO2 max (cardio fitness), ECGs (electro cardiogram), mental health, HRV, oxygen, and more--into a comprehensive health report.
We're compatible with Apple Watch, Apple Watch SE, and Apple Watch Ultra, and can also import and analyze data from third party sleep, health, and fitness apps such as Autosleep, Athlytic, Bright, Cardiogram (HeartIQ), SleepWatch, Tachymon, Welltory, Sleep++, Visible, and other heart rate & HRV monitors.
The today screen gives you a high resolution heart rate (cardiogram), daily deep/REM sleep, and a customized symptom tracker with tags.
