Luna - Period & Cycle Tracker

Track your period, ovulation, symptoms, and mood — privately and offline. Understand your cycle through the four seasons.

Luna is a beautiful, private period and cycle tracker that maps your menstrual cycle to the four seasons — Winter, Spring, Summer, and Autumn — so you can understand your body's natural rhythm at a glance.

Instead of just counting days, Luna shows you which phase you're in, what to expect, and how to make the most of each stage of your cycle.

FOUR-SEASON CYCLE PHASES Your cycle is more than just a period. Luna divides it into four distinct phases, each with its own energy, nutrition tips, and exercise guidance:

• Winter (Menstruation) — Rest and restore. Your body is shedding and renewing.
• Spring (Follicular) — Rising energy. A great time to start new projects and try new things.
• Summer (Ovulation) — Peak energy and confidence. You're at your most social and creative.
• Autumn (Luteal) — Winding down. Focus on completing tasks and preparing for rest.

DAILY LOGGING Track what matters to you, all in one place:

• Flow level (Heavy, Medium, Light, Spotting)
• Mood (Happy, Calm, Energetic, Anxious, Sad, Irritable)
• Symptoms (Cramps, Bloating, Headache, Fatigue, and more)
• Basal body temperature (BBT) for fertility awareness
• Weight and sleep tracking
• Personal notes
