Meet Peri, the first wearable built for perimenopause. Peri turns what your body is actually doing into data you can see, so the phase nobody prepared you for stops being a guessing game. Created by scientists and women's health advocates, and shaped by conversations with 500+ women, Peri gives you your own objective picture of your symptoms, night after night, day after day. HOW IT WORKS: Wear the Peri Sensor. It captures physiological signals continuously and syncs to the app automatically. No manual logging required, though you can add your own notes any time. HOT FLUSHES: Peri does the noticing for you. Your flushes show up in your timeline once the app syncs, so you can see how many you're having, when they cluster, and how that shifts week to week. NIGHT SWEATS: See your night-time episodes laid out alongside your sleep, so you finally know what was behind a rough night. SLEEP: Get a nightly breakdown of your sleep, including time asleep, time awake, restlessness, and watch how it trends over time. HEART RATE & HRV: See your heart rate across the day and night, plus your heart rate variability (HRV), a general wellness measure of how your body is balancing rest and demand. It's there for context on your own trends, not as a clinical reading. CYCLE: Track your cycle through a phase where "regular" often stops applying, and see how your symptoms line up with it. ACTIVITY: See your daily movement and how it sits alongside your sleep and your symptoms. HOW YOU'RE FEELING: Log mood, stress, energy, or anything you want to remember, and see it beside your Peri Sensor data. YOUR PATTERNS: Clear graphs and plain-English summaries of your own data, weekly and monthly, so patterns you'd never spot on your own become obvious. LEARN & CONNECT: Expert-created resources on what's happening in your body, plus a community of women going through exactly the same thing. Peri hands you the data and gets out of your way. What you do with it is your call. THE PERI SENSOR IS REQUIRED: The Peri app works with the Peri Sensor, available at https://www.myperi.co/.
