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.

Hot flashes rarely pick a good moment: the middle of a meeting, the checkout line, three in the morning. Logging one should take a second, not a form. Tap the big warm circle and it's saved. Add how strong it was or what was happening just before, only if you feel like it. HOT FLASHES, DAY AND NIGHT • Day and night are counted separately, because the ones that wake you deserve their own line • Your week at a glance • Log from the app, from Control Center, or just ask Siri HOW YOU FEEL • A quick daily check-in for sleep, mood, brain fog and joint pain, kept right beside your flashes YOUR HORMONE THERAPY • Add what you use: patch, gel, pills or spray, with estrogen, progesterone or testosterone • Mark when you started or changed a dose, and it appears on the same chart as your flashes • On patches? Set your change days once, and a gentle reminder arrives on your lock screen. Mark it done right there • A calendar of the last four weeks of doses and patch changes YOUR PATTERN OVER TIME • A clear chart of your hot flashes across weeks and months, so you don't have to rely on memory READY FOR YOUR APPOINTMENT • A one-page PDF with daily counts, night episodes, severity, symptoms and your treatment timeline • The first question is usually "how often?" Now you can answer from your own record YOURS ALONE • Everything stays on your iPhone. No account, no cloud, no tracking • If you'd like, your hot flashes can also be saved to Apple Health Hot Flash Log is a journal, not medical advice. It doesn't tell you what to take or when. Treatment decisions belong with you and your clinician. MENO PLUS Optional subscription, monthly or yearly with a 7-day free trial, for longer trends, patterns, the doctor's report and trend widgets. Payment is charged to your Apple Account. It renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in Settings > Apple Account > Subscriptions.
