Journal

The things only
you can tell it.

Brin will never decide from your readings that something happened to you. If an event sits beside a change, it is because you wrote it down.

What you can record

Everything you tell Brin, and everything your devices recorded, on one timeline — with what is coming up next.

The Brin journal: what is coming up next, then recorded events and the responses measured around them.
Up next, then events and responses across the window.

Everything it holds

Life events

Twelve categories: legal, medical, injury, illness, therapy, work, social, family, travel, exercise, admin, other.

Private titles

Titles are optional and stay on your phone. Titles never leave the phone. If you turn the Connected Coach on, only the category travels with your question — so you can record that something happened without the app, or anything it talks to, knowing what it was.

Check-ins

How an event actually felt, in your words. Only you say what it meant.

Supplements and medication

Schedules, doses, adherence, label parsing, a product catalogue, and literature lookup via Europe PMC.

The hour, not just the dose

Each row shows when you usually take it, and one tap logs the whole routine at the moment you tap. Timing is part of the intervention.

Workouts

Sessions from any device plus hand-logged training, with distance, pace, steps and climb where they were recorded.

Recovery sessions

Saunas, plunges, naps and breathwork — kept out of training load and measured by what followed instead.

Measured breathing

Guided paced breathing with live beat analysis, scored on the HRV change it actually produced.

Manual readings

Blood pressure, lab results, and anything a device didn’t send.

Recorded, then measured

Anything you log becomes something Brin can measure against. It compares each action with the same time of day on your ordinary days, so a fall that would have happened anyway is not credited to it — and reports plainly when something made no measurable difference.

Breathing has made no measurable difference to your activation across 6 times — the results sit within the noise.
