Period Tracker: Cycle Calendar

Period Tracker is a fast, calm way to keep track of your cycle. Log a period in one tap, see when your next one is expected, and get on with your day — no clutter and no account required.

KNOW WHAT'S COMING
See your next period at a glance, based on a rolling average of your own logged cycles rather than a fixed guess. An optional fertile-window estimate is available if you want it, off by default.

LOG IN SECONDS
Tap once to log today, or pick any past date if you forgot. Add flow intensity and a quick note if you want extra detail — both optional, never required.

A CALENDAR THAT MAKES SENSE
Browse past months at a glance. Logged days and predicted days are shown differently, so you always know what's confirmed and what's an estimate.

REMINDERS, ON YOUR TERMS
Turn on a local reminder a day or more before your period is expected — a quiet nudge from your own phone, nothing tied to a server.

HOME SCREEN WIDGET
Add a widget to check your status without opening the app.

YOUR DATA STAYS YOURS
Everything is stored locally, on your device. There's no account to create and no login. Export your full history to a backup file anytime, and import it back on a new device or after reinstalling — you're always in control of your own information.

SPEAKS YOUR LANGUAGE
Available in English, Arabic, German, Spanish, Persian, French, Hindi, Indonesian, Portuguese, Russian, Turkish, and Urdu, with light and dark themes.

Period Tracker isn't trying to be a wellness platform or a social network. It answers two questions, quickly: when is my period coming, and let me log today.
