Some rumors are circulating about Apple developing a fitness ring. I don’t know if it’s true, but there is a compelling case for a lighter fitness tracking device, whether it’s a ring or a lightweight bracelet. Because a bracelet would compete with the Apple Watch, it seems more likely to be a ring.

Just a few weeks ago, Apple’s Health VP emphasized the importance of obtaining fitness tracking information while sleeping. Many people wear their Apple Watch to bed, but not everyone does (I try to, but sometimes struggle). Even if only worn at night, a ring could address this issue.
