Blood Reports

Understand your blood work in plain language

Upload blood test reports and instantly see what matters, what changed, and what to keep an eye on.

Anonymous Ingestion

Report data is processed without personal identifiers.

Clear Explanations

Each marker includes plain-English meaning and context.

Trend Tracking

Compare results over time to spot improvements or regressions.

Actionable Signals

Highlights what needs attention now versus later.

Blood report insights

Privacy-first by design: uploaded report values are de-identified before analysis so the focus stays on your health signals, not your identity.

AI Health Coach

Goals you set. Plans your data supports.

Tell the coach what you want — better sleep, more energy, a race time. It reads your connected data and builds a plan that fits your baseline, not a generic template.

Goal Intake

Share what you want to improve. The coach asks the follow-ups that matter.

Grounded in Your Data

Every suggestion cites your own sleep, HRV, and activity trends.

Weekly Check-ins

The plan adapts as your numbers change, not on a fixed schedule.

Plain-Language Answers

Ask anything in your own words. No jargon required.
