Your Rhythm

No app knows your body better than you do.

Rhythms helps you build a personal plan that makes you feel better throughout your cycle.

Over time, the guidance shifts from what the science says is likely, to what your body has shown is true.

Phase-aware guidance from day one. Patterns and insights as you use it. Everything you provide (energy logs, task feedback, your journal entries) is used to make Rhythms more personal.

Journaling with a reflection back

Journal the cycle you are in. After enough entries, Rhythms writes you an AI Cycle Reflection, a narrative read of the weeks you just lived.

AI Cycle Reflection · 24 Feb – 23 Mar 2026

Finding the rhythm again

Eighteen entries across your first full cycle with Rhythms. Small, steady, already revealing.

You came into this cycle slowly. The first few days were about staying still and letting the heavier bit pass, and you gave yourself permission to do that without apology. By the first week of March, energy started coming back in quiet doses, the kind that shows up as finishing a proposal or walking further than planned rather than anything dramatic.

The more you use it, the more it becomes yours.

Cycle intelligence

Built for your cycle.
Not a textbook average.

Rhythms predicts your phases based on your unique data. Short cycles, long cycles, short periods, long periods. Every combination is modelled accurately from your first day.

Supports cycles from 21 to 35 days.

Phase model built on peer-reviewed cycle research

Irregular cycle? Shorter menstrual? Update anytime.

If your cycle shifts, update your data in the app. Rhythms recalculates every phase instantly. No waiting, no manual adjustment. Your guidance is accurate from the moment you save.

I was training the same every week for years and wondering why I was wrecked by Friday. Rhythms showed me I was basically punishing myself in the luteal weeks. Swapped in yoga on those days. My body is less angry.

FAQ

Questions, answered.

Rhythms is a cycle aware lifestyle app that gives you personalised daily guidance across nutrition, exercise, work and energy, aligned to your hormonal phase. It's built to help you work with your body rather than against it.

Rhythms is designed for women with a menstrual cycle who want to live in sync with it, whether you're in your 20s, 30s, or 40s. It's especially helpful if you've noticed your energy, mood, focus or appetite shift across the month and want to stop fighting it.

Start by tracking, not changing. Before you overhaul anything, just notice when you feel sharp, when you feel flat, when you want to be around people and when you don't. Once you start seeing your own pattern, pick one thing to shift, leave everything else alone, and that still counts. The goal is to work with yourself instead of against yourself, and that can start anywhere.

No, far from it. The research-backed baseline applies to everyone. Iron and nutrient-dense foods during menstruation help replace blood loss. Rising oestrogen in the follicular phase supports motivation and risk-taking, so scheduling challenging work then aligns with demonstrated physiology. You need to try things out and see what works. Journal what shifts across a few cycles, edit your tasks, log your energy. You are looking for your personal pattern, not a generic template. Rhythms adapts to your exact cycle length and your feedback, so the data you see is specific to you, not a one-size-fits-all model.

Period trackers focus heavily on your period, ovulation, pregnancy, and perimenopause. Rhythms is built around your actual cycle length, listens to what you log, do and journal, and gets more specific to you over time. What to eat, how to move, when to push, when to rest, how to plan your work, all according to your behaviour. The prediction is the starting point. What Rhythms can become depends on how you use it.

No. Rhythms is not a fertility tracker, ovulation predictor, or pregnancy app. We don't provide conception guidance or pregnancy support. Rhythms is a lifestyle companion for women who want to understand their cycle and use it to live, work, eat and train with more ease. If you're actively trying to conceive or are pregnant, please use a dedicated fertility or pregnancy tool alongside appropriate medical care.
