Six questions. Your whole day.

Each morning you answer six simple questions about how your body feels right now. Rhythm OS maps your answers to one of four rhythms and then adapts everything: your plan, your meals, your movement, your mindfulness. All of it built to meet you where you are.

Your Morning Rhythm Check-In

Six honest questions about how you feel right now. No wrong answers. Bloom, Drift, Ground, or Shelter — your rhythm shapes your entire day.

Eat for Your Rhythm

Meal ideas matched to your energy state. Simple, low-effort options for Drift and Shelter. Batch prep suggestions for Bloom. Food that works with your body, not against it.

A Plan Built for Today

Your daily schedule adapts to your rhythm. Bloom days get strategic tasks and energy banking. Shelter days get one thing: rest. The app does the thinking so you don't have to.

Move the Way Your Body Allows

Adaptive movement suggestions for every rhythm. Not a workout plan. A body-aware guide to what movement is possible and supportive today.

Built for your hardest days

Shelter Mode is already inside.

When you're in Shelter, Rhythm OS knows. The app shifts completely. No task lists. No meal planning. No movement suggestions. Just the Quiet Room, a safe, still space that holds you until the storm passes.

Because the most important feature of any tool built for chronic illness is knowing when to ask nothing of you at all.

Built for the days no one talks about.

You've tried every productivity system and none of them account for the days when getting dressed feels impossible.

You're tired of apologizing for canceling plans when your body pulls you inward without warning.

You want a tool that starts with how you actually feel, not how you're supposed to feel.
