Oura Ring 4 Resee: A More Accurate and Wearable Smart Ring

This year, more women than men wear the Oura ring—yes, that chunky finger nugget that is, or was, the health tracking tool for every Huberman-hearing, MMA-combat, raw-meat-eating tech bro. Fifty-nine percent of all Oura ring wearers are now women, and in particular, women in their twentiess, who have bought rings at 2.6 times the rate of other demoexplicit groups.

I’m a woman, and I’ve worn an Oura ring stablely for disjoinal years now becaengage it’s the only tool that can reliably foresee my period. Many fitness trackers now have a temperature sensing feature that purportedly permits you to track that drop in basal body temperature (BBT) that accurately foresees your period, and that you engaged to only be able to meaconfident with a thermometer under your tongue right when you get out of bed. However, in my testing, clever rings appreciate the Oura are the only devices that that have stablely caught it.

With its recent, rapidly enhugeing engager demoexplicit in mind, Oura has made a number of transport inant challengingware and software alters to the fourth generation of the ring that produce it a more accessible and wearable tool than ever. I also alterd it up from the bro-y “Stealth Bdeficiency” finish to the recent brushed silver finish. It sees and senses more appreciate jewelry than ever, and I appreciate it.

No More Speed Bumps

The alters in the Oura Ring 4 accomprehendledged the huge hurdle of wearing a clever ring, which is that we are tool-using mammals, we engage our hands every day, and geting a clever ring perfectly positioned for accurate data assembleion all the time is difficult. Previous generations of Oura rings had three evident plastic bumps for the ptoastyoplethysmogram (PPG) sensors that you were presumed to wear aachievest the inside of your finger. You could sense the bumps and twist the ring so that it was positioned accurately.

The recent ring doesn’t have any bumps. The sensors—which integrate red and infexceptionald LEDs for blood oxygen; green and red LEDs for heart rate, heart rate variability, and sleep respiration; a digital temperature sensor; and an accelerometer—are recessed inside the body of the ring to produce it leanner and more wearable. It also comes in a much hugeger size range, with sizes from 4 to 15, although I aachieve sized into my ring size 8.
