Лучшее

Лучшее приложение для месячных которое у меня когда-либо было. Никакой рекламы, подписок и прочего, только самое необходимое. Плюс привязывается к номеру телефона что очень удобно.

Удобство в простоте!

Ничего лишнего, все самое необходимое! Лаконичный дизайн, понятный интерфейс, особенно радуют напоминания о начале цикла :) Ждем версию для мужчин!

FAQ

How does RedCalendar predict my cycle?

RedCalendar uses the median values of your inputted data to calculate your cycle. This method is designed to be more accurate and honest than using averages or artificial intelligence. The app adapts to your personal cycle patterns over time.

Can RedCalendar help with irregular cycles or medication?

Yes, if you are prescribed pills to regulate an irregular cycle, you can enter your new ideal cycle in the settings. RedCalendar will remember these settings for 3 months to better predict your cycle.

What kind of reminders does RedCalendar send?

RedCalendar sends reminders at 9:00 AM. These include notifications for your cycle starting in 2 days, a day after your menstruation ends, and 4 days before your predicted ovulation. It also prompts you to open the app if your time zone changes, like during vacation.

Does RedCalendar work offline?

Yes, RedCalendar works in airplane mode. You can add your data while offline, and it will sync later when you are back online. This ensures you don't lose any entries, even without an internet connection.
