biocode
For iPhone · Works with Apple Health

See what your body’s been saying.

Biocode shows the health data your iPhone and Apple Watch already collect, each number next to your own usual range. No scores to decode, no account, and nothing leaves your iPhone.

How it works

Real measurements, against your own normal.

Every value is a measurement from Apple Health, shown next to your usual range: the middle of your own last 60 days. You see at a glance what’s typical for you, and every number shows how it was measured.

Heart

Resting heart rate, HRV and more

Night-time dip, ECG recordings, AFib History and heart alerts, with Apple’s classifications word for word.

Sleep

Last night, and the nights around it

Stages, your schedule and its consistency, and the Sleep Regularity Index.

Trends

What changed, with no setup

Thirty days to a year, the biggest changes first, each against its own day-to-day spread.

Vitals

Breathing, blood oxygen, temperature

Overnight vitals from Apple Watch, each with its usual range and the nights behind it.

Labs & records

Your lab results over time

From Health Records, charted against the reference ranges your lab reported, not ours.

Show your work

Every number explains itself

How it’s measured, the formula, its limits, and every raw sample with its source.

What Biocode doesn’t do

No black boxes.

Composite scores blend signals from different parts of the body into one number no one can check. Biocode shows each measurement on its own, so you can see what actually changed.

No composite scoresNo recovery, readiness, strain, stress or sleep scores.
No verdictsWithin or outside your usual range. Never “good” or “bad”.
No accountNothing to sign up for or log in to.
No streaksNo badges, goals or nudges. Notifications are off until you want them.
Private by design
