Apple Watch’s New AI Feature Detects Pregnancy and Early Infections With 92% Accuracy

Smartwatch Will Tell If You Are Pregnant Or Not

A new AI feature developed with data from Apple Watch and iPhone can detect pregnancy with 92% accuracy. This advancement could soon appear in upcoming Apple smartwatches, expanding their health monitoring capabilities beyond fitness tracking.

AI-Based Pregnancy Detection Using Behavioral Data

Apple, in collaboration with the University of Southern California, created the Wearable Behavior Model (WBM). This AI feature analyzes behavioral data collected from Apple Watch and iPhone, applying machine learning to identify health conditions such as pregnancy. Unlike traditional methods focusing on brief data snapshots, WBM processes weeks or months of data for a more accurate assessment.

Large-Scale Study Supports the Technology

The foundation for this AI comes from the Apple Heart and Movement Study (AHMS), where over 160,000 participants shared their data voluntarily. The researchers collected more than 25 billion hours of information, using data from 430 pregnancies across 385 individuals to train the model. The study highlights the effectiveness of behavioral data combined with photoplethysmography (PPG) signals in detecting pregnancy and other health conditions.

Potential Impact on Healthcare and Daily Life

  • Early Pregnancy Detection: Women could receive pregnancy estimates early, without needing immediate clinical visits. This is especially valuable for those in remote areas with limited access to healthcare.
  • Broader Health Monitoring: Beyond pregnancy, the feature can detect infections, sleep issues, and heart diseases at early stages, enabling timely intervention.
  • From Consumer to Medical Device: The Apple Watch is evolving from a fitness tracker to a device that supports medical diagnosis and health management.
  • Supporting Medical Professionals: Doctors can use data from this technology to monitor patient health more effectively.

Recent Developments and Future Prospects

Apple integrated period tracking and other health monitoring features into its watches earlier. In 2024, it added a pregnancy tracking feature. With the new AI-driven pregnancy detection, future Apple Watch models may officially include this capability. Currently, the Apple Watch Series 10 and Watch Ultra 2 are available on the market.
