About

PMOSense

Features
Read full description

PMOSense is a cycle tracking app built specifically for people with PCOS, PMOS, and irregular cycles — where typical 28-day cycle apps often fall short. Most cycle trackers assume your cycle is regular and predictable. PMOSense doesn't. It helps you understand your unique patterns using your logged body signs, cycle history, and fertility data. WHAT YOU CAN TRACK • Period start, end, and flow • LH test strips with automatic camera-based result reading • Basal body temperature (BBT) • Cervical fluid • Energy levels • Mood and stress • Symptoms and custom symptom tracking • Daily notes • Medications and supplements related to cycle health, fertility, and PCOS management WHAT YOU GET • Fertility window estimates that adapt to irregular cycles • Ovulation insights using LH, BBT, and cervical fluid together • Cycle predictions with realistic date ranges instead of a single fixed date • Prediction reviews that compare previous predictions with actual cycle outcomes • Recent cycle timeline showing your logged signs and cycle history • Personalized cycle insights based on your logged data • Mood, stress, symptom, and energy trend insights • Identification of possible anovulatory cycles and irregular cycle patterns • Medication and supplement reminders • Doctor Report — a clear cycle summary you can share with your healthcare professional BUILT FOR PCOS & IRREGULAR CYCLES Whether you experience long cycles, short cycles, irregular periods, or cycles without ovulation, PMOSense is designed to work with real-world cycle variability instead of assuming a perfect 28-day cycle. Confidence indicators help explain when predictions are based on strong patterns and when additional data may improve future insights. PRIVATE BY DEFAULT Your data belongs to you. PMOSense does not sell your personal health information. You can manage, export, or delete your data at any time.
