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.
• Pelvic floor
A one-minute check tells a floor that holds too much from one that needs strength, then guided practices for release, breathing and gentle strength follow your cycle. Log pelvic pain, tension and leaks, see which days of your cycle they gather on, and read short articles on what helps and when to see a doctor.
• Perimenopause and menopause
Counts the days since your last period instead of predicting the next one. Log hot flushes with one tap, night sweats and sleep, see how the gaps between periods are changing, and know when bleeding or a symptom is a reason to see a doctor. With short articles on hormone therapy, sleep, mood and bones.
• Pain diary for painful periods
Log how strong the pain was, where it hurt, what came with it and what you took. See your pain around your period and cycle by cycle, whether your painkillers help, and clear signs of when it is worth seeing a doctor, such as about endometriosis. With short articles on endometriosis, adenomyosis, PCOS and pain relief.
• Reminders
Before your period (1–5 days ahead), on your ovulation day, and for your pill, practice, hormone therapy or pain relief.
• Widgets and Apple Watch
Your cycle day at a glance on the Home and Lock Screen and on your wrist.
• iPhone, iPad and Mac
Turn on Sync with iCloud and the same history is on all your devices, merged day by day. The Mac app is included: one purchase, one Pro.
• 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
A PDF with your averages, your last 12 cycles and frequent symptoms, plus pelvic floor, menopause and pain pages when you use them.
• Pregnancy mode
Week, trimester, due date and the baby's size — the app keeps up when your cycle stops.
• Fertility signs
Basal temperature charted against your cycle day, ovulation tests and cervical mucus.
• Bring your history with you
Import from another tracker, and export your own data whenever you like.
PRIVACY
All cycle data is stored on your device only, and no sign-up is required. If you turn on sync, your history goes to your own iCloud — never to us.
