Luteal is a pause button for the days before your period. If the week before your period turns the volume up on every emotion, and you've sent the text, started the fight, or spiraled before you could stop yourself, Luteal is built for that exact moment. It helps you notice escalation early, put space between the feeling and the action, and come back to your regulated self. HOW IT WORKS • Map your sensitive window. Add your last period and Luteal shows the days emotions may run hotter, before they do. • Tap "I'm spiraling" anytime. A calm, guided flow meets you where you are: rate the intensity, then choose what actually helps right now. • Reach for the right tool. Breathe, ground yourself by naming what's around you, wait out the urge, read a note from a calmer you, or follow a short protocol. • Tune in in 20 seconds. A quick daily moment adjusts the app to how you feel today. • See your pattern. Pattern Proof compares your cycles so you can finally see what repeats, and trust it's the cycle, not you. • Leave notes for future you. Write or record messages to read when a spiral hits, exactly when you need them. PRIVATE BY DESIGN Your entries, notes, and cycle data stay on your device. No account required. Luteal isn't therapy or a medical device. It's a gentle companion for the hardest days of your cycle, so the spiral has somewhere to go besides the people you love. Luteal requires a subscription with a free trial. Terms (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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.
