Femdays - You and your body.

Truly understand your cycle: keep track of your period, track symptoms - your data stays encrypted and private. Try free now!

FemDays helps you track your cycle simply, securely, and affordably.

FOR YOU. FOR YOUR BODY. Log your period, mood, symptoms and more, and see clear estimates: when your next period might arrive and when your estimated fertile window is.

YOUR CALENDAR AT A GLANCE A color-coded calendar instantly shows your period, estimated next period and estimated fertile window. A progress ring on the home screen tells you how many days are left, no searching needed.

TRYING TO CONCEIVE? With Cycle Plus, go further: log basal body temperature, cervical mucus and LH tests, and see them evaluated alongside your other cycle data. All figures are estimates for orientation, not a method of contraception and not a substitute for medical advice.

FOR THE WHOLE FAMILY With Family, up to six people can track under one subscription - each with their own fully private, encrypted account. No one sees anyone else's data.

SHARE IF YOU WANT TO Give your partner or a trusted person targeted insight into your calendar - only if and as much as you choose.

FOR YOUR DOCTOR'S VISIT Create a clear PDF report for your doctor with one tap - even in a different language if needed.

YOUR DATA, YOUR CONTROL Your cycle data is stored end-to-end encrypted - no one but you can read it, not even us. Additionally secure the app with Face ID or Touch ID. Already logging data in Apple Health? FemDays can import it automatically on request, all staying on your device.

ALWAYS WITH YOU With the Apple Watch app, see your estimated next period right on your wrist and log your day with a tap. Reminders for period, pill, temperature and more help you never forget.

IN YOUR LANGUAGE FemDays speaks German, English, Turkish, Arabic, Italian, Spanish, Russian, Polish, Portuguese and French.
