Oura Ring gains FDA-cleared birth control capability through Natural Cycles integration

Oura Ring now integrates Natural Cycles, an FDA-cleared birth control app, enabling temperature-based contraception tracking via the ring's skin sensors. The combined system claims 93% effectiveness for typical use and 98% with perfect use—matching conventional methods. The ring syncs overnight temperature data to Natural Cycles' algorithm each morning. This marks a regulatory precedent: consumer wearables crossing into medical device classification for fertility control, not just monitoring.
