Hair Compass AI  ·  for iPhone

An honest record
of slow change.

Hair changes over months, not mornings. Hair Compass AI keeps the daily record — scalp, shedding, routine, photos, labs — and reads it back with on-device intelligence. Everything stays on your iPhone.

The Today screen: a serif 'Minimal' shedding readout, a copper Compass Score ring at 80, and a quiet ledger of scalp, sleep, stress, and routine entries
Today — the daily ledger
The Trends screen: a three-month shedding line easing from Elevated toward Minimal, dose tick-marks beneath, and the honest note 'Too early to judge — week 20 of 24'
Trends — months at a glance

What you keep

Six quiet records, about thirty seconds a day.

One check-in, and the day is on file. Each record is small on its own; kept daily, they become the only thing that can actually answer "is this working?"

Check-in Scalp, shedding, oil, stress

Discrete taps, not essays. The scales match what clinicians ask about.

Photos Same angle, same light

Standardized capture, so a comparison months apart is a real comparison.

Routine What you actually did

Morning and evening steps, checked off as they happen.

Medications Doses as taken

Adherence lives next to the trend line it's supposed to move.

Labs Ferritin, vitamin D, thyroid…

Results with reference flags, kept where your history can explain them.

Triggers Illness, stress, procedures

The events that echo in your hair eight to twelve weeks later.

On-device intelligence

The analysis never leaves your hand.

Daily insights, deep analysis, and the hair chat run entirely on your iPhone with Apple Intelligence. No account, no server, no third-party AI — your records are never uploaded, because there is nothing to upload them to.

Private by design. Check-ins, photos, labs, and Health data are stored only on your device. The privacy policy is short because there is little to disclose.

The house rule

No before-and-after theater.

You will not find retouched scalps or ninety-day promises here, because hair biology does not work that way. The app waits a full treatment cycle — twenty-four weeks for density — before it will call a verdict, and until then it says so, plainly: "Too early to judge."

Every suggestion inside the app carries its evidence tier, worn openly:

When the science is thin, the label says so — and the design lets it recede.
