Period tracking apps have gained significant popularity in recent years. As awareness around menstrual cycles has increased, so has the demand for tools to help monitor and manage them.

Data suggests that more than 50 million women worldwide use apps to track their menstruation. But is an app really necessary? Can’t a reminder on your phone’s calendar do the same thing?

Well, tracking your menstrual cycle is crucial for several reasons. Firstly, it helps you better understand your body and aids in predicting and managing fertility. Knowing when you’re ovulating can be invaluable if you’re trying to conceive or avoid pregnancy.

Secondly, it can help you manage your menstrual symptoms. Many women and girls experience fluctuations in mood, energy levels and physical symptoms throughout their cycle. By tracking how you feel, you can anticipate when symptoms might arise and identify patterns, which in turn will help you take proactive steps to manage them.

Tracking your menstrual cycle can also provide insights into your overall health. Irregularities in the menstrual cycle could be indicative of underlying health issues such as hormonal imbalances, thyroid disorders, or polycystic ovary syndrome (PCOS).

We know choosing which app to download can be overwhelming. That’s why we’ve put together a list of six of the best ones we’ve come across.

Note: all are free to download, but some charge extra for premium features.
