Red Diary: Body Intelligence

Red Diary is a body intelligence system that learns your unique patterns and helps you understand what your body is telling you — every single day.
Unlike basic period trackers, Red Diary doesn't just count days. It analyzes your symptoms, mood, energy, sleep, and activity across every phase of your cycle to deliver personalized insights and daily guidance tailored to your goals.
SMART DAILY GUIDANCE
Every time you open the app, Red Diary answers the question: "What should I do today?" Phase-aware recommendations for exercise, nutrition, and self-care adapt as your body moves through each cycle phase.
BODY WEATHER FORECAST
Your personal body forecast — powered by your own logged data. Red Diary scans your history, finds recurring patterns, and tells you what to expect today based on where you are in your cycle. Sunny, clear, mixed, overcast, or stormy — see your body's forecast at a glance.
FOUR MODES, ONE APP
