Cycle Sync vs Vellum

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. SMART RESCHEDULING CycleSync connects to your calendar and automatically detects: • Events on heavy-flow days • Events on rest-phase days • Dense meeting days during focus phases (3+ events) One tap on a conflict card opens the Time Slot Picker. Your available slots on better days are pre-calculated. Reschedule in seconds. An undo option gives you 10 seconds to reverse. RULES, NOT GUESSWORK. The recommendation engine is rule-based: 1. Your cycle history predicts your phase for any date. 2. Your phase preferences determine focus or rest classifications. 3. Your calendar events are flagged when they conflict with your classifications. 4. Available slots on recommended-phase days enable one-tap rescheduling.
