Apple’s New AI Reportedly Detects Pregnancy With 92% Accuracy, Study Finds

Apple’s New AI May Soon Detect Pregnancy via Apple Watch With 92% Accuracy, Study Finds

In its continued push into smart health technology, Apple may be gearing up to introduce a groundbreaking feature to the Apple Watch pregnancy detection powered by artificial intelligence. A new study shows that Apple’s latest AI model can identify pregnancy with an impressive 92% accuracy using behavioral data collected from iPhones and Apple Watches.

The research, titled “Beyond Sensor Data: Foundation Models of Behavioral Data from Wearables Improve Health Predictions,” highlights how Apple’s Wearable Behavior Model (WBM) can analyze higher-level health indicators such as sleep quality, mobility, heart rate variability, and other patterns to detect physiological changes associated with pregnancy.

To train this model, researchers used more than 2.5 billion hours of wearable data, significantly improving upon earlier AI tools that relied heavily on low-level, often noisy, raw sensor data. The WBM instead uses data derived from Apple’s Health app, HealthKit, and heart rate (PPG) sensors providing clearer, more reliable insights.

For this study, a pregnancy-specific dataset was built using data from 430 pregnancies, with outcomes including both vaginal and cesarean deliveries. Researchers defined the nine months before childbirth and the month after as "positive" weeks periods marked by significant physiological shifts related to pregnancy and recovery. Other weeks were categorized as "negative."

Additionally, data from more than 24,000 non-pregnant women under age 50 were included to increase model accuracy and reliability.

While the Apple Watch already gathers extensive sensor data, much of it can be difficult to interpret in raw form. The WBM aims to bridge that gap by focusing on behavioral metrics carefully selected and validated by medical experts to reflect real-world health states.

As reported by 9to5Mac, the study demonstrates that Apple’s new AI model can effectively monitor and predict health changes over time. With Apple consistently expanding its health-tracking features, this technology could be one of the next major updates to the Apple Watch potentially transforming how users track reproductive health.
