Living with an unpredictable cycle means tracking what your body's actually doing, not what an app guesses. Lunaire Cycle Tracker is a private, offline period and symptom diary built for people who want to understand their cycle, manage PCOS (recently renamed polyendocrine metabolic ovarian syndrome, PMOS), track fertility, or simply own their own data. Log periods, ovulation, BBT, mood, pain and symptoms — all stored only on your device. No accounts. No cloud. No tracking.
WHAT YOU CAN TRACK
• Period dates, flow and spotting
• Cycle phase — follicular, ovulatory, luteal, menstrual
• Ovulation signs — cervical mucus, position, LH test results
• Basal body temperature (BBT) for ovulation confirmation
• Mood — including PMS, PMDD and luteal-phase changes
• Pain — cramps, ovulation pain, headaches, back pain
• PCOS/PMOS symptoms — irregular cycles, acne, hair changes, weight, energy
• Sleep quality & insomnia
• Brain fog & concentration
• Food diary & cravings
• Exercise, supplements and medications
• Weight and body changes
PRIVACY-FIRST BY DESIGN
Cycle data — periods, ovulation, fertility intentions — is deeply personal.
✓ Everything stays on your device
✓ No account, no sign-up, no email
✓ No cloud sync, no analytics, no ads
✓ Works fully offline
✓ You own the data — back it up or delete it in one tap
SEE YOUR CYCLE, NOT AN AVERAGE
Most apps predict your period from "average" cycle data and quietly hide the variability. Lunaire shows you your actual cycle — the real lengths, the real luteal phase, the real ovulation signs. If your cycle is irregular (common in PCOS/PMOS, perimenopause, or post-pill recovery), you'll see the irregularity clearly rather than have it smoothed into a misleading prediction.
PDF REPORTS FOR YOUR DOCTOR
Generate a clean PDF summary of your cycle history, symptom patterns and ovulation signs — share it with your doctor, gynecologist or fertility specialist in one tap. Months of tracked data is worth more than trying to recall "irregular periods, I think?" in a ten-minute appointment.
BUILT FOR REAL CYCLES
This isn't a wellness app with cycle features bolted on. Every category, every chart, every symptom field was designed around what people who actually track their cycles want to know: when ovulation is happening, how long the luteal phase is, whether PCOS/PMOS symptoms are cycling, and whether HRT or birth control is changing the pattern.
If you have a regular or irregular cycle, PCOS/PMOS, suspected fertility issues, are trying to conceive, or simply want to understand your own body — this tracker is built for you.
