Cycle Harmony

Cycle Harmony helps the people who love you understand your cycle - and show up for you in the right way, at the right time.

Most cycle apps are built for one person. Cycle Harmony is built for relationships. Whether you're tracking your own cycle, supporting a partner, caring for a daughter, or staying connected with a mother or sister — this app gives everyone the context they need to offer real, meaningful support.

FOR WOMEN Track your menstrual cycle with daily entries for flow, mood, symptoms, and notes. Cycle Harmony calculates your current phase and delivers personalized guidance for every day of your cycle — from what to eat and how to care for your skin, to how your energy and emotions are likely to shift. All backed by peer-reviewed research.

FOR PARTNERS, FATHERS & FAMILY Understand what the people you love are experiencing — not just that they're "in a phase," but what that actually means for their energy, mood, and needs. Get daily notifications that tell you exactly how to show up: what to say, what to do, and what to avoid.

FOR MEN Men have a hormonal cycle too — a daily testosterone rhythm that affects energy, focus, mood, and performance. Cycle Harmony tracks your daily rhythm and sends time-of-day reminders aligned with your natural hormone peaks and dips.
