EmberLog
Read full descriptionHide full description
EmberLog is a private menopause and perimenopause companion. Log a hot flash in one tap, check in on your symptoms, track how your treatment responds, and walk into your next appointment with a clear report. SEE YOUR PATTERN Flash load combines how often your hot flashes happen with how strong they are, so one trend shows whether things are easing or building. Daily check ins cover five symptom clusters: vasomotor, sleep, mood, cognitive, and genitourinary. The timeline shows how your cycle and symptoms are changing through the transition. EmberLog never claims to predict a period. KNOW WHETHER TREATMENT HELPS Record hormone therapy and supplement regimens with their start dates. The before and after view compares your own log around each change, so you can see the response instead of guessing. Correlations connect sleep, triggers, and flashes using only your data. WALK IN PREPARED The Menopause Care Visit Report gathers your recent pattern, treatments, and changes into a clean PDF you can print or share with your clinician. The clinical background shown in the app cites its sources on screen: ACOG, The Menopause Society, and the NHS. PRIVATE BY DESIGN No account. Your data lives on your device and in your personal iCloud, synced across iPhone, iPad, Mac, and Apple Watch. No analytics, no tracking. You can delete everything at any time. ALWAYS AT HAND Home Screen and Lock Screen widgets show your day at a glance, the Apple Watch app keeps your log close, and everything stays in sync on iPhone, iPad, and Mac. FREE AND PRO Free includes hot flash logging, the vasomotor symptom cluster, and the visit report. A single lifetime unlock adds the remaining symptom clusters, treatment response, and correlations. No subscription, no recurring charges. EmberLog is informational only. It does not provide medical advice, diagnosis, or treatment. Always discuss symptoms and treatment decisions with your clinician.
Hormone OS

You're not imagining it. The 3am wake-ups, the brain fog before a meeting you prepared for, the week where everything felt harder for no reason you could name. You've probably been told it's stress. Or that you're fine. Or that it's just your age. HormoneOS helps you find out whether there's a pattern โ and gives you the words to raise it. HOW IT WORKS 1. Check in for 60 seconds a day. Speak it or tap it. Mood, energy, sleep, pain, and whatever symptoms you're tracking. 2. Connect Apple Health, if you want to. Your Apple Watch, Oura, Whoop, Garmin or ring already writes sleep, heart rate, HRV and temperature there. We read it โ never write to it. 3. Every week, get your report. Not a dashboard. A short piece of writing about your own last 28 days, naming what showed up together and when. WHAT MAKES IT DIFFERENT Every check-in answers you back. Log a symptom and you'll see something true about your own history โ "that's the 3rd time brain fog has come up this week" โ not a badge for showing up. Your 28 days as one picture. Symptoms, period days and your scores on a shared timeline, so clustering is something you see rather than something you have to work out. Tap any day to read exactly what you logged. Written for the appointment. When a pattern is worth raising, the report gives you the sentence to say out loud. Save it to a list that stays put, so it's in your hand in the exam room weeks later. Your words matter. Note that a kid was sick or you were travelling, and the report factors it in instead of blaming your hormones for a bad week that had a cause. WHAT IT ISN'T HormoneOS does not diagnose anything, and it never will. It reports patterns in data you recorded, in the past tense. It doesn't predict your cycle, tell you what you'll feel next week, or explain why something happened โ that conversation belongs to you and your doctor. We just make sure you walk in with the evidence. PRIVACY Voice check-ins are transcribed on your phone. Audio never leaves the device and is never uploaded โ only the text you confirm. Apple Health access is read-only. We never write anything back. Export everything we hold about you to your inbox, any time, from Settings. Delete your account and all of it goes, permanently. SUBSCRIPTION Free for everyone through January 31, 2027. After that: 14 days free, then $12.99/month or $89.99/year. Logging, trends and your history stay free. Payment is charged to your Apple ID at confirmation of purchase. Your subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Account Settings. Hormone OS helps you notice patterns in your own data. It is not a medical device and does not provide medical advice, diagnosis, or treatment.
