NEW YORK, July 27, 2026 /PRNewswire/ — Natural Cycles, the company behind the first and only FDA-cleared birth control app, today announced its sixth FDA clearance, marking another milestone in the advancement of regulated digital contraception. The clearance covers the company’s next-generation AI-powered NC° Fertility Algorithm, which combines advanced statistical modeling with machine learning trained on tens of millions of real-world fertility data points to deliver more individualized fertility predictions.

The FDA clearance was supported by evidence demonstrating that the updated algorithm maintains Natural Cycles’ established safety and effectiveness while giving many users more Green Days—days when the app confirms pregnancy protection is not needed.
