On Tuesday (Oct. 01)Patently Apple posted a report titled "Finish Company Ōura may launch their Fourth-Generation Smart Ring later this month." Well, later this month turned out to be a mere two days later.

Due to Apple's ongoing research that extends through to patents for a wide range of rings (01, 02, 03 and more), we wanted to present Apple fans with a look at the new Ōura ring 4 so as to familiarize themselves with how Apple's competitor is approaching this market. Below are a few of their just released videos.
