Fitness tracker and smartwatch maker Garmin today announced a new menstrual cycle tracking feature.

Within the Garmin Connect app, you can now log your cycle, daily physical and emotional symptoms, and write personal notes about your period, regardless of whether its regular, irregular, you don't have one, or you're transitioning to menopause.

Once you start doing that, the app will provide period and fertility predictions as well as "educational content on subjects like nutrition and training" based on the current phase of your cycle, Garmin wrote in a news release. When you're on your period, for instance, the app may recommend specific vitamins that have been found to reduce cramping.

Over time, you may be able to identify trends, like how the hormone changes throughout your cycle affect your mood, sleep, metabolism, and appetite, Garmin said.

"Knowing how your body changes during each phase of your cycle can also help you understand what kind of training works best during that phase," the company wrote in a blog post. "And over time, you'll learn how to work with your body to reach your goals. During each phase of your cycle, you can learn something new about how hormone changes can affect your workouts and nutrition."

Plus, if you own a Connect IQ compatible device – including the Forerunner 645 Music, Vívoactive 3, Vívoactive 3 Music, and Fenix 5 Plus Series – you'll be able to access cycle tracking information and "discreet period reminders" right from your wrist. Garmin plans to bring this feature to several other devices in the near future, including the Fenix 5 Series, Fenix Chronos, Forerunner 935, Forerunner 945, Forerunner 645, Forerunner 245, and Forerunner 245 Music.

To try it out, just sign in to the Garmin Connect app on your smartphone or desktop, open the main menu and select Health Stats, select Menstrual Cycle from the drop-down menu, then follow the setup instructions. From there, you can start logging your periods and symptoms.

Garmin is following the lead of rival activity tracker maker Fitbit, which rolled out a similar in-app female health-tracking feature last year.

"Cycle tracking was developed for women, by Garmin women – from the engineers, to the project managers, to the marketing team," Garmin Vice President of Global Consumer Marketing Susan Lyman said in a statement. "In this way we could ensure that we were authentically addressing a woman's actual wants and needs."
