Perimo is a calm, private space to understand your perimenopause — built for real life, not another chore.
TRACK YOUR CYCLE
One tap for period start, spotting, and flow. See your cycle lengths shift over time — with patterns worth mentioning to your clinician, in plain numbers.
HRT & MEDICATION DIARY
Log doses, patch schedules, and adherence. Dose changes are tracked so you can see what happened next — all of it lands in your doctor report.
LOG YOUR DAY IN 30 SECONDS
Hot flashes, sleep, mood, energy, and symptoms like night sweats, brain fog, or anxiety. Quick counters and sliders make daily logging effortless — even offline.
SEE YOUR PATTERNS
Weekly trend charts and a monthly calendar turn scattered symptoms into a clear picture. Streaks gently encourage consistency, because more data means better answers.
AI INSIGHTS FROM YOUR OWN DATA
Every week, Perimo analyzes your logs and surfaces connections you might miss — like how your sleep shifts on high hot-flash days. Plain language, no jargon, and always with the reminder that this is general information, not medical advice.
SYMPTOM LAB — RUN YOUR OWN EXPERIMENT
Wondering if magnesium, an evening walk, or skipping late caffeine actually helps you? Pick one change, keep logging, and Perimo compares your symptoms before and after — then shows the difference in your own numbers on a simple evidence card you can bring to your clinician. Not averages. Not advice. Your own data.
ASK PERI — YOUR DATA, TALKING BACK
Ask Peri answers questions about YOUR patterns — sleep, cycle, medications — using your own logged history, not generic content. Prefer talking? Voice logging turns 30 seconds of speaking into a completed daily log. AI features are optional, clearly labelled, and require your explicit consent; conversations are processed by OpenAI and are never used to train AI models or sold to anyone. Peri gives general information only — it does not diagnose or replace your clinician, and safety-sensitive messages are always directed to real-world help.
DOCTOR-READY REPORTS
Export a clean PDF summary of your last 30, 90, or 365 days and make your next appointment count.
PRIVATE BY DESIGN
Your data is yours. Logs are encrypted, stay on your device when offline, and can be exported or permanently deleted anytime.

Perimenopause can feel unpredictable. Understanding it shouldn't.

NEW: Perimo Plan, a 4-week sleep and night sweats program.
- 5 to 10 minutes a day: a short lesson, one exercise, one thing to do tonight.
- Built on the cognitive behavioural principles recommended by NICE and The Menopause Society: paced breathing, a routine for the 3am wake-up, calmer replies to the thoughts, and the habits that make sleep deeper.
- Day 1 is free for everyone. From day 2 it is part of Premium.
- Measured on your own logs: the app compares weeks 2 to 4 with your first week and shows you the verdict.
- A paced breathing guide that works offline, with gentle haptics.
Also: a clear "Continue with the free version" option on the Premium screen, and smaller fixes.
