You're not imagining it. The 3am wake-up. A heart that suddenly races. A full night of sleep that still leaves you flat. Perimenopause can make nights hard to make sense of — and Apple Watch can leave you with numbers but no clear picture. Perigee brings five Apple Watch readings into one clear morning view: HRV — the small changes in time between heartbeats — resting heart rate, sleep, wrist temperature, and breathing rate while you sleep. Each is compared with what’s usual for you. No athlete score. No mystery grade. WHAT YOU GET EVERY MORNING • A useful morning explanation: what changed, what likely contributed, and one practical suggestion. • Five Watch readings in one place, each beside what’s usual for you. • A plain note when the Watch missed part of the night or needs more nights for a fair comparison. No guessing. TRACK WHAT YOU FEEL • Log a symptom in ten seconds — hot flashes, night sweats, racing heart, brain fog, low mood, poor sleep. • Keep a simple HRT log and see your notes beside your Watch readings over time. Perigee never tells you what to take or change. SEE THE PATTERNS • See which symptoms and Watch readings happened on the same nights. Open the dates, counts and missing nights behind each Pattern. • Export a clean, doctor-ready PDF to bring to your next appointment. WHY PERIGEE IS DIFFERENT Perigee is made for perimenopause and menopause, when sleep, night sweats, brain fog, hot flashes, a racing heart or low mood can be hard to explain. It keeps your symptoms, HRT notes and Apple Watch readings together, so you can see what changed, what repeats, and what to bring to your doctor. FREE, AND FAIR Your Watch readings and history are free, forever. So are symptom and HRT logs. The free plan includes up to one morning summary a week and three a month. Perigee Plus unlocks a useful explanation every morning, full weekly reports, and doctor-ready PDF export. AN HONEST WORD ON WHAT THIS IS Perigee is a wellness and self-knowledge companion, not a medical device. It does not detect, diagnose, or treat menopause or any condition, and it does not give medical or medication advice. It shows your own Watch readings and symptom log so that you — and your doctor — can review them together. Always talk to a qualified healthcare professional about symptoms, treatment, or any decision about HRT. SUBSCRIPTION Perigee Plus is an auto-renewing subscription available as a monthly or annual plan. Eligible new subscribers can start with a 7-day free trial; the Apple purchase sheet shows the offer available to your account. • Payment is charged to your Apple Account at confirmation of purchase. • It renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. • Manage or cancel anytime in your App Store account settings.

You're not imagining it — now you have dates and readings to bring with you.
