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.
EVERYTHING IN ONE SUBSCRIPTION
An active CycleSync Pro subscription unlocks the whole planner:
• Cycle logging, phase prediction and a 14-day cycle outlook
• Dashboard with today's phase and a 7-day week view
• Calendar sync with Apple Calendar and Google Calendar
• Conflict detection and unlimited reschedule suggestions
• One-tap rescheduling with a 10-second undo
• Five notification types: reschedule alerts, phase transitions, period predictions, tomorrow's preview and re-engagement nudges
• Insights: energy curve, seasonal capacities and full cycle history
• Cycle import from Apple Health
• Export your cycle history as JSON or CSV
• Light, Dark and System themes
BEFORE YOU SUBSCRIBE
Onboarding and the plan comparison are free, so you can see how CycleSync works before you pay. The planner opens once your subscription is active, and everything you have already logged stays on your device. Weekly, monthly and yearly plans are available in the app.
PRIVACY FIRST
• All cycle data is stored locally on your device
• No cloud sync and no tracking
• Health data is read-only from Apple Health
• Export your data anytime as JSON or CSV
HOW TO START
1. Open CycleSync and log your last period start date.
2. Connect your calendar using Apple Calendar or Google Calendar.
3. Set your typical cycle length (default: 28 days).
4. Review your dashboard. Suggested reschedules appear automatically.
