Rhythm · Personal Planning

Meals and movement, synced to your body.

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.

Step 2 · Anchoring your cycle

When did your last period start?

This anchors the 4-phase calendar. If you're unsure of the exact day, pick your best guess — you can adjust later.

First day of your last period

Typical cycle length (days)

Most cycles are 26–32 days. Default 28 if unsure.

Step 3 · Goal & Calorie baseline

What are you working toward?

This shapes your calorie target, macro split, and meal suggestions.

Step 5 · Workouts & groceries

A few last things

Strength training — exclude body parts?

Select any you want to skip (injuries, recovery, preference).

Where do you shop for groceries?

We'll tailor grocery picks to what's actually at these stores.

Always include these items

Staples you love — e.g. Silver Hills bread, Kite Hill cream cheese, Fage yogurt. Comma-separated.

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.
