Ovaflow is the PCOS app built for irregular cycles, not despite them. Instead of just logging symptoms, it turns your own daily check-ins into one small, kind thing to do today — and shows you honest patterns in your sleep, mood, cycle and skin, with the real numbers behind them. It's honest about what your body is doing. For irregular cycles Ovaflow shows a realistic range and “normal for you” instead of a false-precision date, and it never badgers you that something is wrong. When it's time to see a clinician, the Doctor Visit Brief turns your history into a clean summary — cycle patterns, symptom frequency and mood — plus questions to ask, so you spend less time re-explaining and more time getting help. Log in seconds: mood, energy, sleep, cycle, a food diary with no calorie counting, and the symptoms that matter for PCOS. Read calm, science-backed lessons on insulin, hormones, nutrition and mood, with sources you can check. Everything is grounded in the 2023 International Evidence-based Guideline for PCOS — written to inform, never to shame, and never diet-culture. Your data stays on your device. No account, no ads, no third-party analytics. We never see what you log — so it can never be sold, shared, or leaked by us. Ovaflow offers education and self-tracking. It is not a medical device and does not diagnose or treat any condition. Always talk to a qualified clinician about your care. Ovaflow Plus is an auto-renewable subscription: $5.99/month or $39.99/year, with a 7-day free trial on the annual plan. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. You can manage or cancel anytime in your Apple Account settings.
