## What is Rhythm?

Track your period, predict ovulation and understand your cycle — free to use, stored on your device, and without judgment.

KNOW YOUR CYCLE
Rhythm predicts your next period, ovulation window, and all four cycle phases (menstrual, follicular, ovulation, luteal) based on your personal data. See your full month at a glance on the calendar.

LOG WHAT MATTERS
Track what you experience each day: flow intensity, pain level (0–10), symptoms (cramps, bloating, headaches, breast tenderness, and more), mood, energy, and personal notes. Rhythm remembers everything so you don't have to.

MEDICATION REMINDERS
Add your pill, patch, ring, or any supplement. Mark each one taken directly from your daily log. Track your adherence over time — Rhythm shows how consistent you've been, always without judgment.

APPLE HEALTH
Connect Rhythm to Apple Health to sync your menstrual flow data automatically. Your health, all in one place.

HOME SCREEN WIDGET
See your current phase, cycle day, and days until your next period right from your home screen. Available in small, medium, and Lock Screen sizes for iOS 16+.

CALENDAR SYNC
Export your predicted period, ovulation day, and fertile window to any native calendar — iCloud, Google Calendar, or any CalDAV-compatible service.

INSIGHTS
Track your average cycle and period length over time. Spot patterns in your body at a glance.

PRIVACY FIRST
Your cycle data is deeply personal. Rhythm stores it locally on your device. We never sell it. The free version shows ads, and you choose whether they can be personalized. You can even use Rhythm without creating an account.

PREMIUM
Go further with Rhythm Premium:
— Advanced Insights: symptom trends, mood history, and energy & wellbeing analysis by cycle phase
— Export your full cycle history as a PDF to share with your doctor
— Ad-free experience

Rhythm is for everyone who has a cycle. No assumptions. No labels. No stereotypes. Just your body, your data, your rhythm.

Predictions are estimates. Rhythm is not a medical device or a method of contraception. Talk to your doctor about any health concern.

SUBSCRIPTION
Rhythm Premium is an auto-renewable subscription (monthly or annual). Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel it anytime in your Apple Account settings.
