Think about it. You could see how your fitness is affected by your period, and it eliminates the need for a whole other app to keep up with your cycle. I also applaud Fitbit for paying attention to women’s health — no other major fitness tracker maker has targeted this neglected demographic.

The trouble is, Fitbit hasn’t implemented this feature very well. Your period data is one of several tiles you can add to your dashboard, and it shows you which day of your cycle you’re on. Tap the card, and a calendar shows up, telling you when it expects your next period and ovulation.

This calendar could really use some work. It alternates between gray and white backgrounds to differentiate between months, which otherwise blend into each other. And the months are labeled with incredibly tiny text, making it easy to lose track of where you’ve scrolled.

Fitbit’s calendar also doesn’t tell you, at a glance, how you felt and behaved each day. On Planned Parenthood’s Spot On, for instance, the calendar uses emoji to show the mood you’ve logged. And in Clue, you can see how heavy your flow was.

Possibly the most egregious part is that Fitbit requires you to manually set period start and end dates in the calendar instead of automatically recording that when you log how heavy your flow is. To quote the app, “logging flow will not add to a period.” You’ll have to enter edit mode to add or edit one. The competing options do so automatically when you log your flow.
