Simple, private period tracking
Youna is a simple, privacy-first period tracking app. It helps you log your cycle, track symptoms like mood, pain, and energy levels, and see predictions for upcoming periods. All your data stays on your device — no accounts, no cloud, no tracking.
Tap on a date in the calendar view to mark it as a period day. You can log the start of your period and the app will help you track the duration.
Select a day on the calendar and use the symptom panel to record your mood, pain level, and energy level for that day.
The app uses your logged period history to calculate your average cycle length, then predicts when your next period is likely to start. The more cycles you log, the more accurate predictions become.
Your data is stored locally on your device. It is included in your standard iPhone backup (iCloud or computer backup) along with the rest of your app data. We do not have a separate cloud backup service.
Delete the Youna app from your device. All data is permanently removed when the app is uninstalled.
Yes — the app works entirely offline. It never connects to the internet.
Youna requires iOS 17.0 or later.
