Orbit Cycle is a private, offline period and cycle tracker built for real bodies — not just a calendar with a red dot. WHY ORBIT CYCLE Most period apps give you one guessed date and call it a prediction. Orbit Cycle shows you an earliest-to-latest range with a confidence level (High, Medium, Low) that gets smarter the more you log — plus a Cycle Health score so you can see, at a glance, whether your cycles are trending regular or not. EVERYTHING YOU NEED, NOTHING YOU DON'T • Quick Log — track flow, symptoms, mood, and cervical discharge in seconds • Smart predictions — period and fertile-window forecasts with a real confidence range, not a single guess • Cycle Health score — a running read on your cycle regularity • Fertility & ovulation tracking • Gyno Visit Prep — auto-detects red-flag symptom patterns, generates questions to ask your doctor, and exports a shareable PDF or clipboard summary before your appointment • AI Cycle Coach — ask questions in plain language; works fully offline too • Body Literacy Library — 22 in-depth articles covering PCOS, endometriosis, fibroids, perimenopause, PMDD, birth control, thyroid, teen periods, postpartum, vaginal health, and more • Period product inventory — tracks how many pads/tampons/cups you actually use and estimates when you'll run out • Light, dark, and alternate themes • Full backup & restore, and one-tap permanent data deletion BUILT FOR EVERY STAGE Whether you're tracking your first period as a teen, managing PCOS or endometriosis, navigating perimenopause, or just want to know when your next period is coming — Orbit Cycle adapts to you. YOUR DATA STAYS YOURS Orbit Cycle runs entirely on your device. No account, no sign-up, no cloud sync of your health data, no ads. Your cycle history never leaves your phone unless you choose to export it yourself. Track smarter. Understand your body. Walk into every doctor's visit prepared. MEDICAL DISCLAIMER Orbit Cycle provides general health information for educational purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment.

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.
