Scientific and straightforward are the two ways Clue likes to describe itself. The app helps you find connections between your moods and symptoms to find patterns about your cycle – you can easily log symptoms like cravings, acne, cramps, and vitality, to figure out what they mean and if they are possibly related to your menstrual cycle. 

Not only this, but you can also log calendar reminders in the app so that you can get notified about the next period, ovulation, fertile window, and PMS cycles. All of this can turn out to be quite useful if you find that you have difficulty tracking your cycles.

Ovulation and Fertility Tracker

It’s a very useful option for women looking to conceive, and for those women who want to avoid it. 

Clue can be a fertility friend for you when you want to conceive by sending you daily fertility predictions. By using this application, you will easily be able to log ovulation tests and cervical fluids if you’re looking for the most accurate ovulation estimates. 

The application has a built-in feature to help you plan for pregnancy by setting reminders in the calendar, so you’re always aware of the optimal days. Fertility reminders can be sent through your phone’s notifications, so you don’t have to open the app to be notified.

Learn About Your Period’s Unique Patterns 

Many women often ignore or are unaware of the bodily symptoms related to menstruation, but they can speak volumes! Clue helps you consider all of these symptoms as you log them in the app to tell you more about what they mean. 

Clue will also help you to figure out if you have irregular menstrual cycles. Not only this, but one brilliant feature that Clue has is its ability to help you learn more about what your irregular periods could mean, providing information on possible signs of PCOS, while considering your menstruation symptoms as you log them.

Additional Tips For Customizing the App

There are many tips for exploring the numerous features on Clue. When you’re using Clue, it would be better for you to tell the app about your birth control method – this can help you get more accurate predictions regarding your cycles and unlock special features. It doesn’t matter if you’ve started using the pill, have recently gone off of it, or that you’re using an IUD. Even if you have just recently started being sexually active, let the application know! It will filter unique content and recommendations for you that way. 

You can also turn off Clue during your pregnancy. The calculations will temporarily stop then, and the small gap will not affect your predictions in any way. They will resume right after you begin menstruating. Other than that, you can keep relevant information up-to-date regarding your pregnancy – for example, the weight, emotions, cravings, and all. 

While using Clue, you can also exclude unusually long or short cycles from the appl so that they don’t affect your averages. An exceptionally long or short cycle might adversely affect the predictions that Clue has set aside for you resulting in the possibility of ovulation days, and your fertile biological window, being predicted incorrectly. To avoid this from happening, you can remove this irregular cycle from the log.


An application like Clue will come in handy for all women around the globe, whether it’s teenagers who have just started their menstruation, women who want to track their cycles, or women during pregnancy. The application caters to anyone who menstruates, in a comforting, gender-neutral language. Tracking your monthly cycle can be much easier with help from Clue.
