Everything Birll
keeps an eye on.

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.

01 — THE MORNING REPORT

A single score,
and the why.

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.

  • Recovery, Sleep & Readiness — the triad, scored 0–100 against your own baseline.
  • Plain-language insight — why today is a push day or a pull-back day.
  • HRV & resting HR — the signals behind the score, always one tap away.
02 — BIRLL AI

An AI coach that
cites its sources.

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.

  • Grounded answers — every claim traces back to logged data.
  • On-device inference — powered by the Neural Engine, private by default.
  • Context aware — knows your caffeine log, workouts and overnight trends.
03 — BIOMARKERS & LABS

Your blood,
annotated.

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.

  • Trend-aware ranges — 88 mg/dL read against months of your own data.
  • 40+ markers — metabolic, lipid, inflammation, hormones, vitamins.
  • Panel history — every draw, side by side, over time.
04 — HRV TRAINING

Train the nervous
system, gently.

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.

  • Live biofeedback — watch HRV respond as you breathe.
  • Session library — down-regulate, focus, or wind down for sleep.
  • The long view — a 90-day HRV trend that rewards consistency.
06 — Vitals & Tracking

One record for
every signal.

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.
