Personalized baseline, not population average

Your body has a pattern. We help you see it.

HaloLocus turns the data your wearable already collects into a personal physiological baseline — built for women navigating PCOS, endometriosis, and perimenopause, whose symptoms are too often measured against the wrong reference point.

How it works

Three ideas, not three features

Most health apps compare you to a population average. We think your own pattern, tracked over time, is the more useful reference point — and we build the model to know the difference.

01 · Baseline

Your own normal, not a generic one

We connect to a wearable you already own and learn what's typical for you specifically — not a threshold set for the average user.

02 · Deviation

Flag what's different, not what's average

When your pattern shifts, you see it early — framed as information to bring to a conversation with a doctor, not a diagnosis.

03 · Context

Built on real physiology, not a symptom diary

Our models are grounded in large-scale, published cardiovascular and hormonal-health research — not just self-reported symptoms.

Who this is for

Built around three conditions

  • PCOS

    Polycystic ovary syndrome

    The most common hormonal condition in women of reproductive age, and one of the most delayed to diagnose.

  • ENDO

    Endometriosis

    Chronic, systemic, and still routinely dismissed as "normal" period pain in its earliest years.

  • PERI

    Perimenopause

    Symptoms often begin over a decade before diagnosis, and are frequently mistaken for something else entirely.

What we're not

A screening tool, not a diagnosis

HaloLocus is built to help you notice meaningful change earlier and bring real information into a medical conversation — not to replace one. We don't diagnose, and we don't promise to prevent disease.

HaloLocus is a prognostic screening tool, not a medical device. It is not intended to diagnose, treat, or prevent any condition. Always speak with a qualified healthcare provider about any change in your health.
