MoodLine
Read full descriptionHide full description
MoodLine is a fast, private mood journal for people who want to notice patterns without turning feelings into a feed, diagnosis, or cloud account. CHECK IN IN ABOUT 15 SECONDS Choose one of five qualitative mood bands. Add optional contexts and a note when useful. Every field after mood is optional. SEE EVIDENCE, NOT CERTAINTY MoodLine waits for enough explicit comparison days before showing a pattern. Each finding names the context, date span, counts with and without it, qualitative direction, and important limitations. An unanswered context stays unknown. MoodLine never claims that a context caused a mood, and it does not diagnose or treat any condition. YOUR DATA STAYS YOURS There is no MoodLine account, advertising SDK, tracking SDK, or mood-data server. Notes, photos, and pattern calculations stay on your device. App Lock can use Face ID, Touch ID, or the device passcode. Readable CSV export and complete backup and import remain free. You can browse, edit, export, back up, or delete every raw journal record without Pro. FREE INCLUDES - Unlimited mood check-ins and notes - All-time raw Timeline browsing, editing, and individual deletion - A 30-day qualitative trend and one qualifying pattern preview - One private local reminder - Readable CSV export, complete backup and import, and deletion controls - A privacy-safe weekly share card - A fast widget and App Shortcuts entry point - Free regional urgent-support information MOODLINE PRO ADDS - Every qualifying personal pattern with comparison counts - A private weekly reflection and curiosity plan - Long-range calendar history, search, and advanced Timeline filters - Custom contexts for events and states that matter to you - One safely downsampled, on-device photo per detailed entry Subscriptions are processed by Apple. The purchase screen shows the localized price, period, trial eligibility, renewal terms, Restore Purchases, and a direct link to manage the subscription. Payment is charged to your Apple ID after confirmation. A subscription renews automatically unless cancelled at least 24 hours before the current period ends. You can manage or cancel it in your App Store account. Ending Pro never deletes or hides your raw journal. MoodLine is a self-reflection journal, not a medical device, crisis service, diagnosis, treatment, or substitute for professional care.

PMDD Tracker & Diary
Read full descriptionHide 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, rage, anxiety, physical symptoms and cycle patterns. WHAT YOU CAN TRACK • Mood — low mood, rage, anxiety, hopelessness, irritability • Sleep quality & insomnia • Energy & fatigue levels • Physical symptoms — bloating, breast tenderness, cramps, headaches • Brain fog, concentration, cravings and appetite shifts • Period dates, flow and spotting — so your luteal pattern is visible • 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, with reminders 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 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 cloud. Your data lives in a local database only you control. • No ads. Ever. No tracking. No analytics. • Works fully offline. PDF REPORTS 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", and most period apps lump them together and miss the pattern. Lunaire PMDD Tracker & Diary keeps your mood log and your period log side by side, so the luteal drop becomes visible from your first full 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 • Eight food and trigger correlations 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.
