Tamu Bulanan: Period Calendar

Overview

Tap a date on the Calendar to mark a period day. On Today, log your flow, symptoms, mood, discharge and notes. Once you've logged at least one period day, the Forecast tab shows when your next period is likely.

Average cycle and period length, fertile window and ovulation are all labelled as estimates, not a medical diagnosis. There's an irregular-cycle mode, custom categories, a make-up fasts (qadha) counter and a PIN lock. Your data only syncs if you sign in and turn on its own permission.

Common questions

Does my data sync?

Only if you want it to. Google sign-in is optional, and Tamu Bulanan data only syncs after you turn on its own permission.

Can I rely on the forecast medically?

No. Every number in Tamu Bulanan is an estimate, not a medical diagnosis. If something worries you, talk to a doctor.
