Your four phases

Know where you are,
every day

Your cycle isn't just about your period. Luna tracks all four hormonal phases so you can understand your whole month.

🌺
Menstrual
Days 1–5
Rest is productive. Your body is shedding the uterine lining — honour your need for recovery.
🌱
Follicular
Days 6–13
Rising estrogen brings energy and clarity. A great time to start new projects and be social.
✨
Ovulation
Days 14–16
Peak energy and confidence. Your fertile window is open — a great time for important conversations.
🌙
Luteal
Days 17–28
Progesterone rises. You may feel more inward. Wind down routines and be kind to yourself.
