PMDD, tracked with the seriousness it deserves. Lunaire PMDD Tracker & Diary is a private, offline symptom diary for people living with premenstrual dysphoric disorder. Log luteal-phase mood crashes, anger, anxiety, physical symptoms and cycle patterns. WHAT YOU CAN TRACK • Mood — low mood, anger, anxiety, hopelessness, irritability • Sleep disturbance • Fatigue and low energy • Physical symptoms — bloating, breast tenderness, cramps, headaches • Difficulty concentrating, cravings and appetite changes • Period dates, flow and spotting — so you can see your symptoms alongside your cycle • 24 built-in symptoms in total • Supplements, and whether you took them • Food, drink and exercise by type and intensity • Weight (kg, lbs or st), blood pressure, pulse and temperature • Appointments and daily notes (reminders with Premium) Every symptom and exercise is rated on a simple five-point scale — you can log the same symptom or exercise multiple times a day. Many people live with more than one condition, so with Premium you can add symptoms of your own and hide the ones you don't use — the lists end up matching you. PRIVACY-FIRST BY DESIGN • No accounts. No sign-up. Open the app and start logging. • No tracking. Your data lives in a local database only you control. • No ads. Ever. No analytics. • Works fully offline. PDF REPORTS (PREMIUM) Generate a clean PDF of your cycle-mood pattern and symptom severity — share it with your doctor, gynecologist or psychiatrist in one tap. BUILT FOR PMDD, NOT PMS PMDD is not "bad PMS". Lunaire PMDD Tracker & Diary keeps your mood log and your period log side by side, so you can see how your symptoms line up with your cycle. FREE • Symptom, mood, period, food, exercise and supplement logging • Up to three entries per symptom per day • Calendar view • Weight, temperature and blood pressure • Appointments • One week of trends and charts • Your complete history, always browsable • Backup and restore to a file you keep • Light, dark and AMOLED themes, plus an in-app language picker PREMIUM • Trends over one month, three months, a year or all time • PDF reports • CSV data export • Twelve entries per symptom / exercise per day • Your own custom symptoms and exercises, plus hiding the ones you don't use • Supplement and appointment reminders • A personalized home screen • Your top eight symptoms instead of three Track PMDD — privately. These screenshots are just a small selection from the app. All screenshots show example data, not real records. Premium: an affordable monthly or yearly subscription, or a one-time lifetime purchase.

If you don't recognize yourself the week before your period — snapping at people, crying, not sleeping, unable to focus — you're not alone. This is what severe PMS and PMDD, premenstrual dysphoric disorder, can look like. Code Red is built specifically for this. Not another period calendar, but a diary that helps you understand what's happening to you and get through the hard days more easily. AN AI ASSISTANT THAT KNOWS YOUR CYCLE • Tell it how you feel: it goes through your symptoms, explains how they relate to your cycle phase and suggests what may help right now • Offers exercises based on cognitive behavioral therapy • Sees your entries only with your permission PMS & PMDD MODE • A daily rating of 24 symptoms structured like the DRSP, the scale doctors use when assessing PMDD • After a couple of cycles you can see which symptoms come back and on which days • A morning heads-up when, based on past cycles, a hard day may be close CYCLE & FORECAST • Your cycle day and phase on the home screen • Period and hard-day forecast based on your own history WIDGETS • Cycle day, days until your period and your day right on the Home Screen — no need to open the app APPLE HEALTH • Period days and symptoms sync both ways • Sleep and resting heart rate are included in your doctor report FOR YOUR DOCTOR • A PDF report or spreadsheet for any period up to a year • Medications and supplements with reminders in the right cycle phase Code Red does not diagnose and does not replace a doctor. The period forecast is not suitable for contraception.
