A mosaic of your cycles and stories.
Mozi is a menstrual cycle tracking and wellness app. Log your period, track your phases, understand your fertile window, and learn about your body — all in one private app.
What's included
Core tracking works immediately — no account needed. Creating a free account unlocks cross-device sync. Premium unlocks advanced modes and requires an account.
Log period dates, flow intensity, and cycle length. A colour-coded calendar shows all four phases. Predictions improve as you track more cycles.
Log your mood, physical symptoms (cramps, fatigue, bloating, headache, and more), and intercourse. Patterns link back to your cycle phases over time.
Articles matched to your current phase and age group (teen or adult). Plain language, no jargon, no ads.
Optional notifications for your upcoming period and daily log prompts.
Week-by-week baby development, due date countdown, trimester milestones, and prenatal appointment tracking.
Fertile window countdown, ovulation timing, BBT and LH tracking, and home pregnancy test logging with line progression chart.
Daily fertility status based on the sympto-thermal method. Informational only — not a certified contraceptive.
Symptom-first tracking for PCOS and perimenopause. No misleading predictions when cycles are unpredictable.
Your cycle history, ovulation data, and recurring symptoms formatted to share with your healthcare provider.
All predicted periods and fertile windows for the year ahead at a glance.
Share your cycle phase and mood with a trusted partner, privately and on your terms.
Chat with an AI that knows your cycle. Ask about phases, symptoms, hormones, and what to expect. Educational only — not medical advice.
