Take advantage of your biology.
One good week a month is not enough. Rhythms helps you make the most of all four.

Your energy, focus, appetite and motivation can shift throughout your cycle. Rhythms helps you understand what may be happening today and what to do about it.

More than a period tracker, Rhythms is a smart cycle syncing app with personalised daily guidance based on your actual cycle.

How Rhythms works

Know your phase, science-grounded.
Your phase forecast comes from a custom-built model based on peer-reviewed research, including a published study of 612,613 real-world cycles*.

Log your period and cycle information to see your phase today.
Rhythms is designed for cycles from 21 to 35 days. Update your cycle details anytime and your phase and guidance are recalculated.

Cycle-based eating.
Discover phase-matched recipes and build a meal plan around what your body may need at each point in your cycle. Turn your plan automatically into a shopping list, making cycle-based eating easier to follow.

Your data is encrypted, locked and yours to delete.
Never sold, rented or traded. Encrypted in transit and at rest, with optional App Lock so nobody else can open Rhythms on your phone. Delete your account at any time, in the app or on the web without signing in, and all your personal data will be removed.

Personalised daily guidance.
Receive phase-aware daily tasks across Food & Nutrition, Exercise, Social, Career, Mind & Focus, Thermal Protocols and Fasting. Thermal Protocols and Fasting tasks are not shown to anyone who selects an age group under 18.

Build a routine around you.
Like or dislike suggestions, create your own tasks, add recipes to your meal plan and shopping list, and shape a personal cycle plan that fits your life.

Reflect and see your patterns.
Log symptoms, activities and energy, and write freely in your phase-based journal to see your patterns. Choose to receive an AI-generated cycle summary based on your entries. AI is optional and can be fully turned off.

Track changes over time.
See your cycle variation, including your shortest and longest cycles. Export your information to support conversations with your healthcare professional.

Sync your cycle with your calendar.
Add your cycle phases to your personal calendar so you can plan ahead.

Share with your partner.
Add up to three people and they receive a short email the day before each new phase begins, or share your phases straight into their calendar. Remove access at any time.

Rest now. Slay dragons later.
Some days are made for intensity. Others call for recovery. Rhythms helps you recognise the difference and respond confidently.
Not by forcing yourself into the same routine every day, but by building one that moves with you.
