Temperature

Your body speaks through temperature. It quietly shows when you ovulate, how your cycle flows, when your hormones shift, and even offers early signs of pregnancy, stress, sleep, and metabolic health. Subtle changes, made visible.

Heart

With every beat, ECG tracking can reveal stress and recovery, sleep quality, cycle-related changes, and shifts in hormones. It can catch early signs of cardiovascular risk, monitor fertility, and follow how your body adapts day by day.

Hormones

Your hormones shape how you feel every day. Estrogen and progesterone guide your cycles, fertility, and mood. Cortisol reflects your stress and recovery. Testosterone fuels your energy and drive.
