Symptom Lab: test what actually helps you
Everyone has advice — magnesium, no caffeine, evening walks. Symptom Lab turns advice into your own evidence: run a personal experiment and see what your data says.
- Pick an experiment — cut afternoon caffeine, try a supplement, start an evening walk — or create your own.
- Perimo compares your symptoms before and during, automatically. No spreadsheets.
- Get a clear evidence card — and it lands in your doctor report, too.
Magnesium supplement
14-day experiment · vs. your previous 14 days
Your own data — not averages, not medical advice. Personal observation, made visible.
Your cycle and your HRT,
finally in one place
The clearest signal of the transition is your cycle — and the biggest "is it working?" question is your treatment. Perimo tracks both, side by side with your symptoms.
- One tap logs a period; Perimo maps your cycle lengths and how they're shifting.
- Patch on Mondays & Thursdays? Model your real schedule, get sound reminders, see adherence.
- Every dose change is remembered — and lands in your doctor report as a timeline.

Ask Peri — the first menopause AI that knows your data
Any chatbot can recite generic advice. Peri answers from your own logs — with real dates and real numbers — and knows when to send you to a clinician instead.
- "Is my HRT working?" gets an answer built from your doses, your sleep scores, your timeline.
- Talk instead of type: say "three hot flashes today, slept badly" and Peri turns it into a structured log — you approve before anything is saved.
- Built with hard guardrails: no diagnoses, no dose advice, crisis-aware, and only with your explicit opt-in. Turn it off anytime.
Not medical advice. Peri never diagnoses — and hands you to a human when it matters.
