- Q & A
Do I need the internet to use the app?
Yes, this is a cloud-based app. All processing is done on AWS servers, and your data is securely stored there. Because an internet connection is required, you may experience slower results when your connection is weak or limited. If you’re not on Wi-Fi, the app may use your mobile data. Rest assured, we never share your data with any third parties.
How Do LH and PDG Levels Affect Ovulation Prediction?
The app uses data from LH (Luteinizing Hormone) and PDG (Pregnanediol Glucuronide) tests to enhance the accuracy of ovulation predictions. Here’s how these biomarkers contribute:
Regular and precise testing for LH and PDG enhances the app’s ability to deliver personalized and scientifically backed fertility insights.
How Will the App Deduce Ovulation Information from Basal Body Temperature?
The app uses your Basal Body Temperature (BBT) to analyze and predict ovulation by identifying patterns in your temperature data. Here’s how it works:
By combining precise measurements with detailed historical analysis, the app provides tailored ovulation insights to help you track your fertility effectively.
How to use LH test?
1. What is LH test?
Ovulation Test Strip is a qualitative test used to predict when there is a lutenizing hormone (LH) surge, and in turn, when you are likely to ovulate.
2. What’s the different between LH test and LH Ultra test?
3. When to Start Testing LH?
If you are new to testing, we recommend tracking your LH levels daily after the last day of your period so you don’t miss your LH surge. And continue testing until you detect the LH peak and observe that your LH levels have decreased and remained low.
4. When is the Best Time to Take an Ovulation Test?
Test any time between the hours of 10:00 AM – 8:00 PM, as this is when LH levels tend to be highest. You’ll just want to make sure you avoid using first morning urine. Test around the same time each day is highly recommend.
Note: Please upload one image per test.
5. How to Test Using the HORMONElife App to Help You Read the LH Test?
1) Prepare the LH Test Strip: Follow the instructions provided with the strip to ensure it is used correctly.
Note: Do not read result after 5 minutes.
2) Tap the “Capture Results” button: Open the APP, in the main interface, find and tap the “Capture Results” button. Choose test type of “LH”, and then select the Interpretation Method:
o Take the Photo:
a. Choose the scan feature in the app.
b. Hold your phone steady above the test strip and capture a clear image. Place the entire test within the strip frame, ensure that the max line and the control line align with the yellow dotted line.
o Choose from Gallery:
a. Select the option to upload an image within the app.
b. Choose a clear photo of your LH test strip from your gallery to upload. Adjust the picture so that the max line and the control line align with the yellow dotted line
3) Wait for Result Analysis: After taking the photo or selecting it, the app will automatically analyze the image and display the test results.
4) Save and Review Results: You can choose to save the results for future reference and review previous test results in the history section.
5. Understanding the Results
Once the app analyzes your test strip, you will receive a result indicating one of the following:
Negative (No LH Surge)
•LOW(0≤LH T/C Ratio＜0.75): LH levels are low, then you have not begun your LH surge and you should continue with daily testing.
•HIGH (0.75≤LH T/C Ratio＜1): A rise in LH levels suggests that ovulation may occur soon.
Positive (LH Surge)
•PEAK（LH T/C Ratio≥1): you will probably ovulate in the next 48 hours. During this time, you’ll have a higher chance of getting pregnant.
T/C Ratio:
LH test have two lines: the test line (T) and the control line (C). The T/C ratio compares their color intensity to show luteinizing hormone (LH) levels in urine.
•T/C Ratio of 1.0: Test line is as dark as the control line, indicating peak LH levels.
•T/C Ratio Less than 1.0: Test line is lighter, indicating lower LH levels.
•T/C Ratio Greater than 1.0: Test line is darker, indicating higher LH levels.
In short, aim for a T/C ratio of 1.0 to detect your LH peak.
6. What Should My LH Hormone Chart Look Like?
Your LH hormone chart typically shows a slow increase over several days, leading to a peak and then a quick decline. Alternatively, it may rise quickly in one day and then drop back down. The way your LH levels rise—gradually or quickly—will shape your chart. Some women may also see a double peak or a flat pattern before reaching the main LH peak.
If you are new to ovulation testing, consider testing twice a day to identify if you have a rapid LH surge (LH rising in just a few hours) or a gradual LH surge (LH rising over the course of a few days). Once you know your pattern, you can test once a day if your LH surge lasts more than one day but twice a day if your surge is less than one day.
7. Tips for Taking Photos of Test Results
l C= Control line; T=Test line; Max=Max line
l Timing for Taking Photos: After completing the test, please take a photo within 5 minutes to record the result. Results displayed after 10 minutes may be invalid, so make sure to capture the image within the valid timeframe.

How to use FSH test?
1. What is FSH?
Follicle-stimulating hormone (FSH) is secreted by the posterior pituitary gland and changes with the menstrual cycle, which is very important for regulating the endocrine function of the ovary. It can promote the development and maturation of follicles, if the level of FSH is abnormal, it will affect the menstrual cycle and ovulation of women. It is suggested that women aged 20-40 should be monitored at any time to know whether the body’s endocrine is normal in time; Whether it is suitable for breeding; And whether there is a tendency of premature ovarian failure, go to the hospital for diagnosis and treatment in time.
Follicle Stimulating Hormone (FSH) Test Strip is a rapid chromatographic immunoassay detection of FSH in urine. Your test results can be used to screen your fertility and evaluate ovarian status.
2. When to Perform a FSH Test
You can conduct a FSH test using one of two methods:
1) Based on App Recommendations: T The app will notify you to start testing for FSH on the third day of your menstrual cycle, continuing for three days.
2) According to FSH Test Strip Instructions: Alternatively, you can follow the instructions provided with the FSH test strips to determine when to start testing. (FSH test should start on the third day of the menstrual cycle. Because the FSH level may fluctuate, it is suggested to test it on the third, fourth and fifth day of the menstrual cycle.)
3. What is the best time of day to test this strip?
The test should be used first thing in the morning. If first morning urine is not tested, results may be inaccurate.
4. How to Upload Your FSH Test Results Using the App
Follow these steps to capture and save your FSH test results:
Prepare the Test Strip: Insert the FSH test strip into your urine sample as per the instructions. Wait for 5 minutes for the results to develop.

How to use LH Ultra test?
- What is LH Ultra Test Strip?
The LH Ultra test strip is a home-based ovulation test that detects luteinizing hormone (LH) levels in urine. A surge in LH indicates that ovulation is approaching, allowing you to time intercourse for conception effectively.A rapid increase (Surge) in LH occurs approximately 24-48 hours prior to the release of an egg from your ovaries- a process know as ovulation. You are at your most fertile on the day your LH surge is detected and the day after.
- When to Start Testing?
If you are new to testing, we recommend tracking your LH levels daily after the last day of your period so you don’t miss your LH surge. And continue testing until you detect the LH peak and observe that your LH levels have decreased and remained low.
There are also two methods to determine when to begin testing for LH:
Based on App Recommendations:
Open the “HORMONElife” app and tap on the “+” icon on the homepage to input the start dates of your last three menstrual cycles. The app will provide tailored recommendations for when to begin testing, typically suggesting starting two days before your predicted fertile window.
According to the Instruction Manual:
Alternatively, refer to the test kit’s instruction manual for guidelines on when to start testing based on your cycle length.
- When is the Best Time to Take an Ovulation Test?
Test any time between the hours of 10:00 AM – 8:00 PM, as this is when LH levels tend to be highest. You’ll just want to make sure you avoid using first morning urine. Test around the same time each day is highly recommend.
Note: Please upload one image per test.

Understanding Fertility: Chance of Conception Across the Menstrual Cycle
Understanding the chance of conception on each day of your cycle is crucial for effective family planning. Let’s delve into this concept！
Research has shown that the likelihood of conception varies throughout the menstrual cycle. The highest chance of conception occurs during the fertile window, which includes the days leading up to and around ovulation. Ovulation, the release of an egg from the ovary, typically occurs in the middle of the cycle. Being aware of the chance of conception on each day is essential for maximizing your chances of getting pregnant. By tracking your cycle and identifying your fertile days, you can plan intercourse strategically around ovulation. Studies indicate that timing intercourse during the fertile window increases the probability of conception.
By understanding your fertility and the chance of conception on each day of your cycle, you can make informed decisions about when to try for pregnancy and increase your chances of success.
Note:
Please be aware that the chance of conception can vary based on factors such as age and menstrual cycle. It is important to know that this information should not be used as a method of contraception.
