4 phases, one rhythm.
Every cycle has four distinct phases, each with its own energy, mood, and physical needs. Luteal tracks them all and tells you what to expect — every single day.
Follicular
Days 6–13
Estrogen rises, energy returns. This is the best time to start new projects, exercise, and socialize. Your mood naturally lifts.
Ovulation
Days 13–17
Peak estrogen and LH surge trigger ovulation. You feel radiant, confident, and social. Fertility is at its highest.
Luteal
Days 17–28
Progesterone rises, then drops if no pregnancy. Energy slows, introspection deepens. Good time for journaling and self-care.
Partner sharing
Built for connection.
Invite your partner to your space. They see your phase, your mood, and how to support you — all in a private, consensual way. No oversharing. No guessing.
