Your personal
algorithm.

We'll send a single hello the moment Hertally opens. That's it. Welcome — we've been waiting for you.
How it works
Three things, working as one
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.
Tracked every day — by your wearable and the little you log.
Sleep, temperature, cycle, symptoms, mood. Hertally learns your normal, then gently shows you what shifts.
The research is read for you — more than 100,000 studies, matched to your life.
Continually updated, always in plain language. The evidence finally meets the person it's about.
It's all woven into an algorithm that is entirely your own.
Your patterns, your baselines, your history — yours to keep, export, or erase, always.
For too long, the person who knows the most about your body — you — was the missing piece.
That's the whole reason Hertally exists.
With your doctor
Walk in with the full picture
Hertally doesn't replace your clinician — it makes the time you have together count. Invite your doctor to view your data directly in the app, so the conversation starts from everything your body's been telling you, not a blank page.
+ Invite your clinician to observeThey observe; the two of you decide — and you can revoke access any time.
