Cycle Tracker, an app that helps women keep track of their menstrual cycles, has now come to Apple Watch. While limited bike tracking has been a part of Apple's iOS Health app since 2015, with the launch of iOS 13 and WatchOS 6, Cycle Tracker is now its own discrete sector within the Health app on the iPhone and a separate app on the Apple Watch.  Designed to offer various health benefits that help with family planning and reproductive health problems, irregularities and symptoms, you can now enter and view data directly on your watch.
For those who may be a little crippled by the prospects of an app that tracks your periods, think this way: Apps can track your heart rate, what you eat, how many calories you burn lying on the couch and read your phone, and how many steps you forced yourself to walk every day. Tracking your periods is just another health-related statistic that could come in handy, even if you're not someone who usually focuses on details beyond marking an X in the kitchen calendar and breathing a relief when it's over. Bike tracking information, also visible through the redesigned Health app on iOS 13, is encrypted on the device. If you use iCloud backup, that information is also encrypted in iCloud. If you are someone who emphasizes the details, there are many possibilities in Cycle Tracker.
The Cycle Tracker is good for tracking fertility, allowing you to record statistics such as basal body temperature or the results of an ovulation test. The app uses that information to create a fertility window – a few days each month when you're likely to become pregnant. The more information you provide the app, the more accurate the predictions can be. When you use Cycle Tracker continuously, you get more and more accurate statistics and predictions about your cycle, such as the average length and flow for your periods, which can help you recognize a health problem if results start to change over time. But follow Apple's warning not to use its fertile windows as a form of birth control or to diagnose a health condition. However, it is good for information to collect and share with healthcare professionals.
When you set up the Cycle Tracker, you can enter data on your bike history – including the date of your most recent period, its typical length and the length of your bike. You can enter this data manually or you can confirm data already in the Health app or from third-party apps you already use, such as Clue, Glow or a host of others.
The fertile window will be the six days you are likely to be fertile, based on your stated data or a positive ovulation test result. The fertile window is based on a traditional calendar and is calculated by subtracting 13 days from the estimated start date for the next cycle. If you enter a positive result of the ovulation test, the fertile window forecast is adjusted so that day five of the fertile window coincides with the first positive ovulation test result in a cycle.
Using Cycle Tracker on your watch
When you enter information in Cycle Tracker on your Apple Watch, it will sync with Cycle Tracker on your iPhone within the Health App. Here's how to enter important tracking information in the Watch app.
Track your bike: To track your bike from your Apple Watch, open the Cycle Tracking app, swipe to the correct date, and then press the oval to log in your period.  Touch Digital Crown on your Apple Watch to see all available watch apps.
Track all the disgusting symptoms you suffer each month within the Cycle Tracker app.
- Pressure Symptom .
- Select all symptoms that apply to you.
- Print Issued .
Check the date for your next and last period: If you want to check the dates from your Apple Watch opens the Cycle Tracking app and then scrolls down to Period Prediction or Last Menstrual Period.
Check your period or the fertile window via color-coded symbols: A light blue oval marks your six-day fertile window. Red stripes on a circle mark when your period begins. Massive red circles track period days. Purple dots mark days when you logged in information.
Set notifications for period and fertility tracking: Predictions are based on data you enter and begin after entering your last period in the app. If you log in a period before it is predicted to start, you will not receive a prediction message for that cycle.
If you don't need the app
Let's face it, some women find it useful to keep track of this type of reproductive health information, especially if fertility or irregular cycles are a problem. However, many may not care or are not interested in recording more information than simply marking the calendar on the fridge. If it is you, there is an option to simply remove the Cycle Tracker from your Apple Watch and do it with it. To do so, press and hold the app icon until all apps rotate and tap X in the upper left corner.
