I'm Juno. I'm not going to tell you to drink more water. What I do is keep track. Every symptom you log, every cycle, every bad night's sleep — I hold onto it. When a pattern turns up, I'll tell you what it is and how sure I am about it. The reason that matters: next time someone tells you it's probably nothing, you'll have months of data that says otherwise. A RECORD THAT HOLDS UP IN AN APPOINTMENT Symptoms, periods, sleep, mood, medications, food and weight — logged in a tap or two, not eight questions a day. Out of that comes the doctor report: a PDF with your cycle history, how often each symptom actually turned up, what you're taking, and your lab results over time. It's free, and it stays free. It is harder to wave off a chart than a description. PATTERNS YOU WOULDN'T SPOT YOURSELF "Your bloating runs higher in the three days after you sleep under six hours — eleven times out of fourteen." That is the kind of thing I go looking for, and I will always tell you whether it's a pattern or a cause. It is never a cause. FOOD, FOUR WAYS Photograph the meal, scan the barcode, read the label, or just type the name in. The numbers come from a nutrition database rather than from a model's imagination, and the app names which of the four it used every time. No food gets a grade here. Describing what something is made of is not the same as ranking what you chose to eat, and I only do the first one. ALSO IN HERE • Cycle prediction that copes with cycles that don't behave • Lab results tracked over time — AMH, testosterone, HbA1c and nine more • Ask me about your own record, in your own words • 74 exercises and eight sessions, none of them assigned to you • What the research actually says about supplements, including where it says very little • A goal weight you set for yourself, and the daily energy that follows from it • Reminders that only ever say take, never log • Steps, weight, workouts and sleep from Apple Health, read-only — nothing is written back WHAT I WON'T DO No streaks. No guilt about the fortnight you didn't log. No opinion on your weight or your dinner. And no diagnosis — I'm a record, not a doctor. What I'm for is making sure the person who is one has something in front of her. FREE, AND PREMIUM Logging, your full history and the doctor report are free forever, and nothing you have already written down is ever locked away. Premium adds the pattern-finding, cycle prediction, chat, lab tracking and food tracking beyond the free monthly entries. Seven days free first, so you can find out whether I turn up anything in your record. If I don't, the app still does the thing you came for. — PCOS Juno does not diagnose, treat or prescribe, and it is not a substitute for medical care. Premium is an auto-renewing subscription, monthly or yearly, with a 7-day free trial once per Apple Account. Payment is charged to your Apple Account at the end of the free trial unless it is cancelled at least 24 hours before the trial ends. Manage or cancel in Settings › Apple Account › Subscriptions.
