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.

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.

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.

Yes. Rhythms draws on established research in women's endocrinology, chrononutrition, and exercise physiology, translated into practical daily actions. It's guidance, not medical advice.

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, 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.

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.

Rhythms is built to consumer health data privacy standards for Australia, the US, and the UK. We never sell your personal data or share it with advertisers, and you can delete your data whenever you choose.
