Private offline period tracker for cycles, ovulation and symptoms. No account.
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. 📧 Contact Support: admin@hamatim.com
