Context vs Beluga

Context unifies your health data from Oura, Whoop, Apple Watch, Fitbit, Strava, Withings, Apple Health and more into one powerful dashboard. It also allows you to track what your wearables can’t, see how everything connects, and finally understand what’s actually working in your protocol. The goal is simple: experience more good days by getting real insights from your wearables, biometrics, and daily patterns. Context is private by default and human by design. ALL YOUR HEALTH DATA IN ONE PLACE See your complete health picture across every device and app you use. Connect your Oura ring, Whoop, Apple Watch, and more, and switch wearables without losing your history. No more jumping between six different apps to understand your health. The following metrics sync automatically from your connected wearables and apps, no manual entry needed: sleep, HRV, heart rate, blood oxygen, steps, workouts, weight, body fat, calories, respiratory rate, and more (full list below). Layer in custom annotations for everything else. PLUS, TRACK YOUR FULL CUSTOM HABIT STACK OR PROTOCOL Your health is more than what a wearable measures. Use our custom annotations feature to log things like supplements, peptides, creatine, cold plunges, sauna sessions, contrast therapy, TRT doses, GLP-1 injections, fasting windows, NAD+, acupuncture sessions, meditations, nootropics, cortisol, caffeine timing, energy levels, mood, symptoms, diet, hormone therapy, blood panels, DEXA results, and anything else in your stack or that matters to you - you name it. If it matters to your protocol, Context can track it. DISCOVER WHAT ACTUALLY WORKS Context shows you correlations between your daily choices and your health metrics. Did that cold plunge improve your deep sleep? Is your supplement stack moving your HRV? How is your new protocol affecting your energy and recovery? Over time, see what’s actually driving change. Run your own experiments, and get real answers. CONNECTS WITH: Oura, Whoop, Apple Watch, Fitbit, Strava, WithingsSmart Scale, Apple Health and more.
