Do you wear a smart ring for sleep tracking or fitness data capture? If so, it’s probably from Oura or another small company. It’s certainly not from Samsung or Apple … or at least not yet.
Samsung just announced a smart ring. From my story at Forbes:
Samsung just launched a smart ring that will track your sleep habits as well provide a simple and unobtrusive way to monitor fitness indicators like breathing, heart rate, and motion. Now it’s time for Apple to admit that its sleep tracking hardware—AKA the Apple Watch—isn’t an ideal form factor for the task.
