Oura’s new Horizon sleep-tracking smart ring is well-rounded in shape

Whether the price increase from $299 to $349 is worth it for the rounder Horizon ring is up to you, based on your style preference. You still get very good sleep tracking with the Horizon, and for some, wearing a ring to bed is less tedious than an Apple Watch — both comfortable and coping with constant charging (the Oura can last up to a week on a charge). And it’s certainly cheaper than the $950 Gucci version of the Oura Ring that came out this year, which also has a pretty rounded design.
