What does it do? When it’s idle, it will do heart rate checks and calorie burn counts, like any fitness band we have. There’s a blood oxygen sensor, which is an impressive addition, and its top surface can act as a controller. Swipe around short videos, skip music tracks, presentation slides, or flip pages in an ebook reader. It can also work as a remote shutter for a paired phone’s camera — all pretty convenient stuff.
The HiFuture Ring costs $199 from the official website, though we’d at least like to see them add more sizes before recommending anyone go and buy it for anything else other than curiosity and hunger for tech.
