Your wearable knows what happened. Bivryn tells you why. "Why do I feel off today?" "Is coffee wrecking my sleep?" "Did that actually help?" Most health apps wait for you to ask. Bivryn reads your Apple Health stream every morning — sleep, HRV, recovery, blood work, behaviour, weather — names what changed and the likely reason, and tells you whether what you tried last time worked. The daily reading is free, with the wearable you already own; membership adds the patterns and the answers. TODAY One calm reading of how your biology is landing, from sleep, HRV, resting heart rate, respiratory rate, wrist temperature, bedtime timing and travel. The Arc behind it draws your last 24 hours. Under it, the day ahead with clock times — how long the morning holds, when the dip lands, whether the evening comes back — and this week against last, in numbers. WHY Ask anything — why am I tired this week, what changed in my last 14 days — and Bivryn reads across a year of your biology to answer. PATTERNS Correlations across your behaviour and biology you'd never spot by hand, including the 1, 2 and 3-day delays where the real signal usually lives. PROOF Try one change at a time — a supplement, an earlier dinner, a training protocol. Bivryn captures your baseline, tracks adherence, and tells you honestly whether your biology actually moved. LABS Upload a lab PDF. Bivryn reads cholesterol, ferritin, vitamin D, hs-CRP, glucose, thyroid and hormone markers, and connects them to your sleep, energy and recovery. MEMORY When today's biology matches a day from your own history, Bivryn surfaces what came next, over a living timeline of travel, recovery stretches and supplement changes. LONG ARC Bivryn Bio Age: a continuous reading from up to nine channels, scored against your own baselines and published ranges, computed on your device. RIGHT NOW Breathing, mindful walks, eye rest, light reset — with the HRV change measured before and after. WORKS WITH WHAT YOU ALREADY WEAR Apple Watch, Oura, WHOOP, Garmin, Withings and lab panels all flow in through Apple Health. Bivryn reads every source you have and tells you which one recorded last night. PRIVACY BY DEFAULT Your biology stays on your device, syncing only to your own iCloud account if you choose. We don't sell your data or share it with advertisers. Export everything as JSON, or delete everything, with one tap from inside the app. Requires iOS 17 or later. Apple Watch supported but not required. On-device interpretation of the free reading uses Apple Intelligence where available. Bivryn is not a medical device. It provides informational and educational insights about your biology and is not intended to diagnose, treat, cure or prevent any disease. For medical concerns, consult a healthcare professional.
