Orbit Cycle: Period Tracker

About this app

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.
