How to use Cycle Tracking on Apple Watch and iPhone

Period tracking apps have been around for several years now. But from iOS 13 and watchOS 6, you can use cycle tracking on Apple Watch and iPhone as a native feature.

This lets you log your monthly period, menstrual symptoms, sexual activity, and more on the Health app on your iPhone and the accompanying Cycle Tracking app on Apple Watch. It’s helpful for family planning and keeping tabs on your overall wellbeing.

To start using Cycle Tracking, you first have to set it up in the Health app on your iPhone. Then, you can log your data whenever you need to on your phone or Apple Watch. The app uses your data to predict and notify you about your next period, most fertile days, and more.

This guide will walk you through everything you should know about Cycle Tracking on your iPhone. But before starting, here are some points to keep in mind: 

  • Cycle tracking and fertility predictions cannot be used as a form of birth control. They are an approximation at best. 
  • You can never use data from the Health and Cycle Tracking app to diagnose a health condition. Consult a medical practitioner for any guidance about your health. 
  • You can also use Cycle Tracking with third-party apps such as Clue and Flo, which integrate with the Health app.

Now, let’s check out how to use Cycle Tracking to track your menstrual cycle and fertility on iPhone and Apple Watch. 

To start tracking your menstrual cycle, you first need to add a few details to the Health app.

How to set up Cycle Tracking in the Health app on iPhone

  1. Open the Health app and go to the Browse tab. 
  2. Tap Cycle Tracking.
  3. Tap Options next to Cycle Log.
  4. Scroll down and select Period Length to enter your approximate period length.

How to customize Cycle Tracking on iPhone

The Health app lets you select which aspects of your cycle you want to log each day, week, and month.

  1. Open the Health app and go to the Browse tab.
  2. Tap Cycle Tracking
  3. Tap Options next to the Cycle Log.
  4. Toggle on Symptoms.

  • Sexual Activity

  • Cervical Mucus Quality
  • Basal Body Temperature, and

Get period predictions and notifications on iPhone

One feature of Cycle Tracking that has made my life a lot easier is period predictions. This shows you the approximate date of your next period, so you’re not caught unaware. You can also turn on notifications to alert you a week ahead of time before your predicted period. 

Predictions are calculated using the data you input about your period and cycle length. Predictions dynamically change over time to become more accurate as you enter more data. 

Here’s how to set it up:

  1. Open the Health app and go to the Browse tab.
  2. Select Cycle Tracking.
  3. Tap Options next to Cycle Log
  4. Toggle on Period Prediction. This will generate a two-month period prediction calendar.
  5. Toggle on Period Notification to get alerted about your upcoming period and reminders to log your daily data.

How to get fertility predictions and notifications on iPhone

If you’re trying to conceive, Cycle Tracking can help you know your most fertile days each month. Similar to period predictions, fertility predictions are based on data you input about your period or a positive ovulation test result.

Your fertile window is calculated by subtracting 13 days (the luteal phase) from the estimated start of your next cycle.

Suppose you enter a positive ovulation test result. The prediction will adjust to make the fifth day of your fertile window coincide with the first positive ovulation test result in a cycle. Here’s how to set up fertility predictions and notifications: 

  1. Open the Health app and tap Browse
  2. Select Cycle Tracking 
  3. Tap Options next to Cycle Log.
  4. Toggle on Fertility Prediction to generate a three-week calendar of your next fertility window. 
  5. Toggle on Fertility Notification to get alerts about your upcoming fertility window.

  • Red stripes on a circle indicate your predicted period. 
  • Solid red circles indicate your logged period days.
