Rhythm - Sleep & Energy Coach

Sleep better. Feel sharper. Live in sync with your body clock. You have a built-in rhythm that decides when you feel sharp, sleepy, hungry, and ready to focus. When you work against it, nights feel restless and days feel off. When you work with it, sleep comes easier and energy stays steady. Rhythm is a circadian coach that maps your personal rhythm and tells you what to do, and when. It learns from your sleep, activity, and daily patterns — no wearable required — and turns the science of circadian timing into simple, well-timed nudges across your day.
