Generic wellness apps are built around male physiology. Rhythm plans around your actual hormonal rhythm - whether that's a 28-day cycle or a steady daily one - and adapts meals, workouts, and grocery picks to where your body is today.
Step 1 of 5
Rhythm adapts to how your body actually works
What's your daily rhythm?
This shapes your entire plan - food, movement, and energy are all calibrated to your body's pattern.
💡
Did you know? Women biologically operate on a ~28-day hormonal cycle - estrogen, progesterone, LH and FSH all shift week to week. Men's hormone cycles are primarily 24-hour (testosterone peaks in the morning). Most nutrition and fitness research is built on male physiology, which is why generic advice often doesn't feel quite right for women.

A note: Rhythm is a design demo - not medical advice. Real hormonal health varies person to person, and anyone making changes to nutrition, exercise, or cycle tracking should talk to a qualified practitioner. The science of female-specific training and cycle-syncing is still emerging and not every study agrees; this tool tries to reflect what's reasonably supported while leaving space for your own body's feedback.
