Ovulation measuring APPs have become an indispensable part of our lives and can help us better control our own fertility cycles. However, when using these apps to measure ovulation, we need to pay attention to some issues.

Secondly, we need to ensure the accuracy of the APP. Although these APPs can give some prediction results, their prediction results may have certain errors. Especially if a woman's cycle is very unstable, these predictions may have large errors.

Finally, we need to pay attention to the limitations of the APP for measuring ovulation period. These apps can usually only predict a woman's ovulation period, but not her menstrual cycle or pregnancy. Therefore, we need to be careful when using these apps and not rely solely on them to make fertility decisions.

To sum up, although the APP can help us better control our own fertility cycle by measuring ovulation period, there are some issues that need to be paid attention to and we cannot rely solely on them to make fertility decisions. If you are considering pregnancy, it is recommended to consult a doctor to understand your physical condition and fertility conditions before making a decision.
