Read full description

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.
