Top 5 Applications of the Menstrual Cycle

"In addition to the numerous other health apps, you can now also track your menstrual cycle via smartphone. The individual periods of the menstrual cycle, the best time to get pregnant, the most fertile days... there are more and more apps for cycle tracking. Discover our top 5 here, recommended by the Sisters and the entire Period Slip team!"
 
The best cycle apps:
 

My Cycle Period:

The app offers a pleasant, girlish design without being over the top. It is very intuitive and has the advantage of being completely free. You can enter various useful information about your menstruation: the start date of your period, cycle regularity... Depending on your preference, you can also enter various additional elements into the calendar: characteristics of cervical mucus and bleeding, pain intensity, dates of intercourse, contraceptives... Thanks to the accuracy of My Cycle Period, you know exactly when your ovulation cycle and its various phases begin: luteal phase, follicular phase, etc.
"For example, if you are trying to get pregnant, you can use this app to find out the dates of your most fertile days. Additionally, the notifications remind you of your gynecologist appointments. The app is suitable for young girls in puberty up to women in menopause and allows for a fairly comprehensive health monitoring: sleep, weight, activity... the only possible downside of the app is that it is only available in English, which might deter some users who are not very familiar with this language."
  

Menstrual Period Tracker:

The design of the app is intentionally kept simple: a calendar on a white background with a few colors to mark the days of menstruation and ovulation. The main features of a cycle app are offered: adding daily notes, predicting menstruation and ovulation dates, as well as access to the history of past cycles for global evaluation. For example, you can observe whether your cycle is regular or irregular and when you suffered from premenstrual syndrome. Additional features allow you to note the timing of your pill intake, monitor your body temperature daily, and indicate the dates of sexual intercourse or the presence of cervical mucus. You can even save the result of an ovulation test!
You can choose from 6 different languages and receive regular advice on nutrition or health. Menstrual Period Tracker is especially suitable for women who wish to conceive: With the app, you will learn the best time for pregnancy and can even plan sexual intercourse temporarily.
The negative aspect of this app can also be positive for some users: its minimalism. If you are a fan of sophisticated designs and feature-rich apps, you will be disappointed here: Menstruel Period Tracker offers only basic functions and a rather simple virtual calendar.
 

Flo:

Thanks to its own color code, the Flo app allows users to easily find the information they need. Blue stands for ovulation periods, red for menstrual cycles, the pregnancy calendar is orange, the graphics are yellow, and your daily notes are pink. Fans of very feminine apps will enjoy Flo. In addition to cute animals, colorful flowers, and smiling babies, you can even change your background image according to your current mood. The app is quite easy to use and tells you, apart from the classic information, when you can have unprotected sex if you are not using contraception. 
The app Flo offers comprehensive health monitoring, as you can record illnesses, the frequency of your physical activities, your stress level, and the frequency of your alcohol consumption. Additionally, it provides entertaining questionnaires about changes in your libido. Despite its numerous qualities, the colors used in the app's design may deter some users and are more appealing to young girls.

Glow:

This cycle app is packed with useful information that is relevant for both women trying to conceive and teenagers who want detailed information about their menstrual cycle. You can calculate when your next period is due, track your pregnancy, or get an overview of your cycle. What makes Glow special are certainly the many tips for users. From ideas for balanced recipes to tips for stress management, you will feel well taken care of in every way with this app.
Another strength: The partner can also use the app by linking his profile with that of his partner. He then also receives advice, e.g. on how to pay more attention to his partner during her premenstrual phase. The Glow forum also provides space for discussions with other users of the app. Glow is only available in English and can be difficult to use for those who have little or no command of the language, especially regarding the forum.
  

Clue:

Clue is a very comprehensive app with a simple, elegant design. The colors facilitate intuitive use. Each time you fill in the required information, additional questions are asked to provide more precise information. From your mood to the color of your vaginal secretions to your PMS symptoms - the variety of processed information is impressive.
"If you then add more general data about your health to this information, you will receive a serious and informative follow-up." 
Clue also provides an overview of past cycles, making it a tool for better understanding your period and the effects of hormones on your body. A free version and a second, paid version are offered. This way, you can choose the desired level of information and follow-up for yourself. Although some details could be more precise (more moods to choose from or a more accurate estimation of menstruation dates), the app is still very comprehensive and well thought out.
 
 

Our app ranking

 
1- Clue, our favorite app:
Clue not only offers a great design, but it is also very comprehensive and provides precise information. The very intuitive navigation, even for beginners, also contributes to the quality of this cycle app.
 
2- My Cycles Period, the most accurate app:
My Cycles Period is certainly the most reliable cycle app, especially regarding ovulation and menstruation data. It is therefore very suitable for women who wish to have a child. For women who are not using contraception, it accurately indicates when the risk of becoming pregnant is low, so they know when they can have unprotected intercourse.
 
3- Menstrual Period Tracker, the most minimalist app:
The advantage of this app is the easy and quick access to all useful information. At a glance, you can view the ovulation calendar, your most fertile days, or the length of your cycle. Ideal for busy, yet well-organized power women.
  
4- Flo, the most playful app:
Through her glamour style, she offers an entertaining use. You can enter information daily and even change the design according to your mood. With the various charts created from the entered information, you can analyze all your data more easily.
 
5- Glow, the best app for couples
"It is the only app that involves the partner in the control of the menstrual cycle. If you and your partner want to conceive a child, involving the future father can strengthen the couple."
 
With 8 different sizes and 3 absorbency levels, the period panty is suitable for every woman.
