What are the best apps for menstruation?

Among the flood of apps out there, some are free, others are paid. Some are also more focused on fertility and pregnancy planning, while others are more concerned with tracking contraception and sex life, for example.


This app lets you enter directly what you want to focus on: pregnancy plans and fertility monitoring, cycle tracking, etc...

The main advantage of this app is that it lets you generate graphs from your information. This gives you an overview of your cycle length, weight, sleep and PMS symptoms.

The application also allows you to include daily reminders for your pill, for example.

Period Calendar & Tracker

Period Calendar & Tracker works in the same way as Clue: by entering some of your personal details and indicating the changes you experience over the course of the month: moods, discharge, pain, etc. You also receive a notification informing you of the date of your period.

The application is in English only.

Bonus: you can customize the color of your calendar.


This is an iconic application for tracking menstrual phases! It's very complete and offers multiple functionalities. It was developed by a Danish entrepreneur, Ida Tin, who couldn't find a solution that met her needs for tracking her cycle.

So she developed Clue. The application is very simple to use: all you have to do is enter your moods, pains, feelings, motivations, libidos, white discharge, PMS symptoms, the duration of your menstrual flow, the date of your last period, your height, weight, age, the contraceptive method you're using, etc., as the days go by.

The data provided by users can be used by research laboratories to improve the status of women. The app is available on iOS and Android.

My Calendar Period Tracker

My Calendar Period Tracker is a well-known app with over 70 million users. It works in the same classic way as the others. The information you enter when you download the app, then throughout your cycle as you feed it, enables the app to better predict your next cycles and different menstrual phases.


As with Flo, Glow offers different monitoring depending on whether or not you want to conceive a child. But that's not all!

The most inclusive is Glow. In fact, it allows users to identify themselves as "male users", since men can also have their periods.

The app is also very interesting in that it has a community aspect, allowing users to interact with each other on a dedicated forum.

A little plus: this menstruation app also has a self-love aspect, sending out motivational messages every day.

However, the app is only available in English!


Eve is also a period-tracking app. But it differs in several ways:

It offers a whole host of resources designed to help women cope better with their periods. A host of articles, advice and fun quizzes on women's sex lives are available.

There's also a discussion area where users can help each other.

The app is available in English only, on iOS and Android.

You can use the apps to better live your whole life as a woman: whether you're pregnant or not, whether you're on the pill or not.
