Hertally is a women's health intelligence platform. It weaves your body's signals, your own observations and the latest research into one record, surfacing the patterns that are yours — across every stage of life and any condition you live with: cycles and PMOS, pregnancy, perimenopause and menopause, and autoimmune, thyroid, pain or other long-term conditions and treatments.

Is Hertally a medical device?

Hertally provides descriptive insight only. It is not an assessment of your health, a prediction, or a replacement for your doctor. It supports the conversation with your doctor and is engineered to a medical-device (EU MDR Class IIa) standard and is GDPR-first.

Women at any stage of life, ages 18 and over — whether you're tracking your cycle and symptoms, trying to conceive, pregnant or postpartum, navigating perimenopause and menopause, or living with an autoimmune, thyroid, pain or other long-term condition and want your data ready for any consultation.

Hertally is in an invite-only closed beta. Apply with your email at https://hertally.com and each application is reviewed personally.

In her own words

For too long, the person who knows the most about your body — you — was the missing piece

That’s the whole reason Hertally exists.

For your doctor

Hertally doesn’t replace your doctor.

It makes the time you have together count. Invite your doctor or medical professional to view your data directly in the app, so the conversation starts from everything your body’s been telling you, not a blank page.

Your doctor observes — the two of you decide together.

Why Hertally exists

The missing piece was always you

One idea holds the whole platform together — read top to bottom, it’s a single line of thinking, not three separate claims.

Most health records are written about you — rarely with you

Your signals — and your own observations — count as real data

What your body does, and what you notice about it, logged together and taken seriously — to surface the patterns that are yours, and no one else’s

Every stage

One record that grows with you

Hormones are only part of it. Whatever you’re living with — an autoimmune condition, thyroid, endometriosis, migraine, chronic pain, a treatment you’re going through — Hertally plots your data points and your own observations in one record, ready to support any consultation.

20s

Cycles, symptoms and everything alongside them

Painful periods, endometriosis, PMOS, migraine, thyroid, skin, mood — logged from the start.

30s – 40s

Trying to conceive, pregnancy, postpartum — and the conditions that don’t wait

Autoimmune conditions, thyroid, fibroids, anxiety and depression, chronic pain, long-term medication — tracked next to everything else.

45 – 55

Perimenopause, named and tracked

Alongside blood pressure, joint pain, sleep, migraine, autoimmune flares — whatever is changing for you.

60s & beyond

Menopause, bone & heart health

Arthritis, osteoporosis, diabetes, heart conditions, recovery after treatment — one record for every appointment.

Descriptive

Hertally describes your own logged data against your own baseline. It is not an assessment of your health, a prediction, or a replacement for your doctor.

Yours to keep

Your patterns, your baselines, your history — yours to keep, export, or erase, always.
