Period Tracker, PCOS & PMOS

Lunaire Cycle Tracker is a private, offline period and symptom diary for anyone managing PCOS (recently renamed PMOS) or tracking fertility.

WHAT YOU CAN TRACK
• Period dates, flow and spotting
• Cycle lengths and history — your real pattern, cycle by cycle
• Basal body temperature — the app learns your luteal phase from it
• Mood — including PMS, PMDD and luteal-phase changes
• Pain — cramps, ovulation pain, headaches, back pain
• PCOS/PMOS symptoms — irregular cycles, acne, hair changes, energy
• Sleep quality, brain fog and concentration
• 32 built-in symptoms in total
• Food diary, cravings, exercise and supplements
• Weight (kg, lbs or st), blood pressure and pulse
• 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.
