Oura Ring Now Offers FDA-Cleared Birth Control Tracking

Oura Ring has integrated Natural Cycles, an FDA-cleared birth control app that uses the ring's temperature sensors to track fertility. The system claims 93% effectiveness with typical use, matching conventional methods. Overnight temperature data syncs daily to Natural Cycles' algorithm. This marks a significant shift: consumer wearables are now crossing into active medical device territory for contraception, not passive health monitoring.
