Period Tracker & Calendar

Period Tracker & Calendar is a private cycle tracker and period calendar that works fully offline. No account, no sign-up, no email address - just a clean calendar, cycle estimates, and a health diary stored in a local database on your phone.

✨ WHY THIS IS A GOOD OFFLINE PERIOD TRACKER

🔹 Works offline - no internet needed
Log your period on a plane, in a clinic, or with mobile data off. Predictions are calculated on your device from your own history.

🔹 No account, no sign-up, no email
Open the app and start. There is nothing to register and nothing to verify.

🔹 No ads and no subscription
No banners, no interstitials, no ""go premium"" pop-ups. Nothing in the app is locked behind a payment.

🔹 Private by design - your diary stays on your phone
Dates, symptoms and notes are stored only in a local database on your device. There is no account and no cloud sync, and we never sell your personal health data.

🔹 Period & cycle calendar
Mark your period start and end dates on a clear month calendar. See your current cycle day, your last period, and the predicted start of your next one at a glance.

🔹 Ovulation & fertile window
Predictions are calculated from your own cycle history, then used to estimate your ovulation day and high-fertility window - useful whether you are trying to conceive or just want to understand your body's rhythm.

🔹 Symptom, mood and flow logging
Record daily symptoms, mood, flow intensity and free-form notes. Track cramps, headaches, bloating, breast tenderness and other PMS patterns across cycles.

🔹 Irregular cycles and PCOS
If your cycles are irregular, the app does not force a single 28-day assumption. It keeps your own history, shows your average and your range, and displays cycle lengths over time - useful for tracking periods and symptoms alongside PCOS or when you are monitoring irregular periods and want a log to show your doctor.

🔹 Cycle statistics & history
Average cycle length, average period length, a cycle-length chart for the last 6 months, and a scrollable period history.

🔹 Reminders (opt-in)
Set a reminder a chosen number of days before your period is expected, at the time you choose. Notifications are off by default and only ever ask when you turn them on.

🔹 Export a report for your doctor
Generate a PDF report or a CSV file of your period history from the Home screen. Keep the CSV as a backup, or send the PDF to a doctor. You can also import a backup CSV back into the app.

📌 GETTING STARTED
1. Open the app and tap + to add your most recent period with its start and end dates
2. Keep logging - after a couple of cycles, predictions are based on more of your own logged history
3. Open Settings to pick your language, choose reminder timing, or export a backup

Available in English, Spanish, Portuguese, French, German, Italian, Dutch, Japanese, Korean, Turkish, Polish, Thai, Vietnamese, Indonesian, Hindi, Arabic, Russian and more.

Period Tracker & Calendar is a tracking tool, not a medical device. Predictions are estimates based on your own logged history and are not a substitute for medical advice or for any method of contraception.

Thank you for choosing a period tracker that respects your privacy.
