Fitbit's Charge 3 and Charge 4 both come with female health-tracking, which the company says is aimed at helping women to "learn more about your menstrual cycle — and your body — so you can better understand how it affects other aspects of your health and fitness." If you've just picked up a Charge 3 or the new Charge 4 and need a little help setting up the female health tracking feature, here's how.

How to "opt-in" to the female health tracker

Before you can track your ovulation, you'll first have to opt-in to use the female health tracker. Fitbit users who identify as females on their profiles will receive an opt-in notification, and from there, they'll be able to use the feature. However, if you didn't receive the notification or you don't identify as female, but you'd still like to use the tracker, it's super simple.

  1. Tap edit on your Fitbit dashboard or long press on one of your existing dashboard tiles until they all start shaking.
  2. Add the female health tracker by tapping the "+" icon in the top left corner of the tile.

Now that you've gotten the female health tracker tile on your dashboard, it's time to get tracking.

How to input period data

During its initial launch, the female health tracker will ask a series of questions about your menstrual cycle, which will assist the tracker in making more accurate predictions about your upcoming periods, fertility windows, and ovulation days. For the tracker to accurately predict your ovulation day every month, you'll have to enter the start and end dates of your period, along with how long your period typically lasts each month.

  1. Input the start and end dates for your period by tapping the date on the calendar.
  2. Then tap the pencil icon to add/edit your period information. You can also tap and hold each date.

Once you've inputted the data, your period length for the month will be highlighted from start date to end date.

How to keep track of your ovulation on Fitbit Charge 3 or Charge 4

Based on the information provided, the tracker will show your estimated ovulation date. The tracker is color-coded, so you'll need to check the calendar key to make sure you're focused on the right thing.

The trends page will provide additional details about your ovulation days for as long as you've been using the tracker. It will take your ovulation day from past months and provide an average estimated ovulation date right at the top of the page along with an average period length and your average cycle length based on data previously added.
