NEW! The FREE Clearblue® Period & Cycle Tracker app is a wellness app that can be used alone or with Clearblue® Advanced Digital Ovulation Test or Clearblue® Digital Ovulation Test.
Period and cycle tracking apps
Period and cycle tracking apps are increasingly used as they empower women to understand more about their body, track symptoms and changes during their cycle, prepare for their next cycle, and for some others to help them understand their most fertile time to try for a baby.1 Monitoring their cycles with such apps can also help women have informed conversations with their healthcare professional.1
Clearblue® Period & Cycle Tracker app
The FREE app allows a woman to track her period, and is designed to help her understand where she is in her cycle, give her an indication of her fertile days and when is the earliest she can test for a pregnancy.
When used in combination with Clearblue® Ovulation Tests, it will identify her High2 and Peak fertile days based on her personal hormone levels.
The app is designed with the needs of different women in mind, and offers three different ‘modes’ to choose from according to her personal goal. She can choose from the options below:
- Try for a baby
- Track her cycles (predicting her fertile days, her periods, etc),
- Predict her periods.
This app is not for contraceptive use.
App features
The Clearblue® Period & Cycle Tracker app clearly shows her where she is in her cycle, prompts her when to use an Ovulation Test and offers her relevant educational content.
Fertile days: Insights and Predictions
The app offers her insights based on published Clearblue® data, which shows how the day of LH surge detection varies even for women with the same cycle length.3 The percentages shown below the dates on the calendar indicate the probability of when she may reach peak fertility (i.e., could detect her LH surge) on a particular day based on clinical data from many women, e.g., 25% of women with the same cycle length as her detected their LH surge on this day. Her predictions for fertile window, peak fertility and expected period are based on her cycle length, her last period date and Clearblue® published data for women with the same cycle length as her.3
Data logging
The app provides a powerful tool for her to closely monitor her cycles. She can log and track her periods, her period flow, sex and conceiving methods as well as key symptoms related to her menstrual cycle. The app also enables her to log Ovulation Test results.
Logging a High and Peak Fertility result from a Clearblue® Advanced Digital Ovulation test or a LH surge result from a Clearblue® Digital Ovulation Test replaces the probability prediction with her personalized results.
Other ovulation test results can be logged but you will not get personalized results. Clearblue® (and its owner SPD) take no liability for non-Clearblue® tests and their results used with this app.
Clearblue® Advanced Digital Ovulation Test
Please note the availability of some products may vary in different countries worldwide.
Clearblue® Advanced Digital Ovulation Test is over 99% accurate at the detecting the LH surge. The test identifies the fertile window by monitoring two key fertility hormones: estrone-3-glucuronide (E3G) and luteinizing hormone (LH). By measuring these two hormones, the Clearblue® Advanced Digital Ovulation Test typically identifies 4 or more fertile days4 to maximize a woman’s chances of conception.5
Inside the digital test holder is a sophisticated algorithm that adapts to a woman’s individual hormone levels to accurately identify her fertile window. The Clearblue® Advanced Digital Ovulation Test sets a personalized threshold level for each woman, by measuring changes in hormone levels from their unique personal baseline.
Clearblue® Advanced Digital Ovulation Test gives unmistakably clear digital results. An empty circle on the result screen indicates low fertility and she should test again the next day. When she sees a ‘flashing’ smiley face she has reached high fertility, where she has a greater chance of conceiving. She should continue to test each day until the smiley face result becomes ‘static’ as this indicates she has reached for peak fertility time.
Clearblue® Digital Ovulation Test
Clearblue® Digital Ovulation Test is over 99% accurate at detecting the LH surge6, accurately identifying the best 2 days to get pregnant naturally, with unmistakably clear digital results. The test works by setting a personalized threshold level for each woman, and measuring the change in LH level from their unique personal baseline.
An empty circle on the result screen indicates no LH surge was detected and she should test again the next day. A smiley face indicates the LH surge has been detected, i.e., she has reached peak fertility in her cycle.
Cycle summary
Within the app she can find a summary screen showing the cycle days corresponding to her fertile window and peak fertility, in addition to her cycle length and period length. She can also choose up to 3 symptoms to compare between her current and previous cycles.
Data privacy
The data collected is minimized to only what is strictly necessary to allow the app to function (i.e., to help her track and understand her cycles and make predictions). That is why the app will not ask for her email, phone number or name, nor to create an account.
