One score every morning, an AI that cites your data, bloodwork in plain language, and a record of every vital — from glucose to cycle to stress. Here's what's inside.
Every morning Birll reads your overnight signals and writes a short report: the number, the direction it moved, and the one decision that follows from it.
Ask anything — "why was my sleep broken?" — and Birll answers from your real numbers, then shows the receipts. Inference runs on-device; your raw signals stay on your phone.
Upload a panel and Birll reads every marker against your trend — not just a lab's one-size range. Optimal, borderline, low; what it means and what moves it.
Guided breathwork sessions that move your heart-rate variability in real time, with an editorial trend chart that shows the work compounding week over week.
Ninety days in, Birll surfaces durable cause and effect: bed before 11pm earns +9 recovery the next day. Quiet correlations, written down where you'll see them.
Beyond the score, Birll tracks the full picture of your body — logged by hand, photographed, or synced from a device. All of it lands in one timeline.
Nutrition
Log meals or snap a photo. Macros, fiber and meal timing sit right next to your glucose and recovery.
Stress
Continuous stress derived from HRV and heart rate, mapped across your whole day.
Cardiac
Log cuff readings or sync a monitor; pressure trends sit beside your cardiovascular markers.
Metabolic
CGM or finger-stick, charted against meals, sleep and movement to reveal what spikes you.
Cycle
Phase-aware tracking — recovery and readiness adjust to where you are in your cycle.
Vitals
Resting heart rate, respiratory rate, SpO₂ and skin temperature, captured every night.
Sleep
REM, deep and light sleep — with the disruptions that quietly cost you recovery.
Movement
Steps, active minutes, workouts and training strain pulled from any source you wear.
Body
Weight, body fat and lean mass trends from your smart scale, tracked over months.
