Ovulation Tracking Apps Guide

Tracking ovulation to get pregnant is serious business. Following the wrong information could mean a missed opportunity for pregnancy. With so many to choose from, which is the best one to use? For this guide, we review applications that mainly use algorithms, artificial intelligence (AI) or calculations based on your cycle start and stop dates. 

Educated Guess vs. Accurate Predication

Any application to predict fertility that is based on algorithms, AI or other types of calculations, rather than your biological signs, is predicting fertility using an educated guess based on statistical averages (either your averages or averages based on a general population). Even with the most advanced algorithms, if you aren’t using your own biological clues in conjunction with the apps, you may miss your specific fertile window.

Biological clues that can help pinpoint the fertile window include: cervical fluid, temperature and the luteinizing hormone detected via urine strips.  If you chose not to manually record your biological signs (the majorit of the apps below allow for that data input), the apps in the guide can be a great way to help you record and keep track of your cycle and fertility data.
