Can fertility apps actually predict ovulation?

In this episode of FERN Rising, Dr. Ashley Burton breaks down the research on ovulation prediction apps and why period trackers often fail to accurately identify the fertile window — even in women with “regular” cycles. Drawing from multiple peer-reviewed studies, she explains why calendar-based algorithms miss true ovulation timing, how LH-confirmed data exposes major prediction errors, and why most apps don’t properly use key fertility biomarkers like basal body temperature and cervical mucus.
