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. GLP-1 MEDICINE LOG Using a GLP-1 medicine? Record the dose and the injection or tablet day your prescriber set, then log each dose, side effects and your weight in kg, lb or stone. A weekly card shows your next scheduled dose, how many weeks you have been on your current dose and what you noted this week. Works with GLP-1 medicines such as tirzepatide (Mounjaro®, Zepbound®) and semaglutide (Wegovy®, Ozempic®). Perimo only records what you were prescribed and never calculates or recommends doses. Perimo is not affiliated with Eli Lilly or Novo Nordisk; medicine names are trademarks of their owners. 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. PREMIUM Perimo Premium unlocks Symptom Lab, weekly insights, reports and full tracking. Start with a 7-day free trial, then choose Premium Yearly ($49.99/year) or Premium Monthly ($9.99/month). Payment is charged to your Apple Account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel anytime in your App Store settings. Perimenopause can feel unpredictable. Understanding it shouldn't. — Privacy Policy: https://perimo.app/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
