CYCLE-AWARE CALENDAR CycleSync helps professional women align their work schedules with their natural menstrual cycle phases. Instead of fighting through low-energy days, you get smart suggestions to move demanding meetings to days when your focus and energy peak. WORK WITH YOUR RHYTHM, NOT AGAINST IT Your cycle isn't an obstacle. It's a compass. Menstrual Phase (Winter) Rest and recovery. Reschedule high-stakes meetings. Follicular Phase (Spring) Rising energy. Schedule creative work and planning. Ovulation Phase (Summer) Peak performance. Take on negotiations and leadership. Luteal Phase (Autumn) Focused wind-down. Finish projects and organize.
