## Description

Log your period with one tap — the app predicts your next one and your ovulation. All your data stays on your device.

Calendar Girl is a simple, private period tracker. Log your period with one tap and the app works out when the next one is due and when you ovulate.

WHAT YOU GET

• Period and ovulation predictions
The app learns from your history — the more cycles you log, the more accurate it gets. Average cycle and period length are calculated for you.

• A calendar you can read at a glance
Period days, fertile window and ovulation, each in its own colour.

• Today screen
Cycle day, current phase, days until your period and ovulation, and your chance of pregnancy — all in one place.

• Daily log
Mood, 16 symptoms (cramps, headache, bloating, acne and more), flow, intimacy, water, weight and a note.

• Statistics and charts
Cycle length month by month, averages, frequent symptoms, mood distribution and your full cycle history.

• Reminders
Before your period (1–5 days ahead) and on your ovulation day, at a time you choose.

• Home screen widget
Your cycle day and days until your period, without opening the app.

• PIN and Face ID lock
Your diary stays yours.

• Sync with Apple Health
The app reads the period days you already track in Health and writes new ones back.

• A report for your doctor
One PDF page with your averages, your last 12 cycles and your most frequent symptoms.

• Optional iCloud backup
Turn it on and a copy of your history is kept in your own iCloud, so a new phone starts where the old one stopped.

PRIVACY
All cycle data is stored on your device only, and no sign-up is required. If you turn on the backup, the copy goes to your own iCloud — never to us.
