Don’t waste money on the Oura Ring 5: I review smart rings for a living, and this Ring 4 Prime Day discount is the only deal that matters

(Image credit: Future)I’ve worn both rings, and I’d say that while the Ring 5 is smaller and thinner, the reasons to buy the newer ring are mainly aesthetic ones. The Ring 5 disappears on your finger, but that’s not to say the Ring 4 is bulky or ugly. In fact, some days I switch back to my Petal Oura Ring 4, as I do love the look of the ceramic ring, and I’ve never worried too much about looking like I’m wearing a fitness tracker.Like Apple, Oura has rolled out all the new software features to the older ring, including Live Activity Tracking, Blood Pressure signals, and the new Women’s Health Features. Sure, the Ring 5 has a day longer battery life and slightly better sensors, but when the Ring 4 is $234 cheaper today, I’m not sure these upgrades are justified. From a data and metrics perspective, the two rings are the same. Like Apple, Oura has rolled out all the new software features to the older ring, including Live Activity Tracking, Blood Pressure signals, and the new Women’s Health Features.Notably, the Ring 4 can also hold more data if you’re someone who doesn’t sync your Ring to your phone every morning. The older Ring can hold seven days of data, whereas the Ring 5 can only hold three days of data on the ring itself.I’ve been covering Prime Day long enough to know we won’t see any discounts on the Oura Ring 5 this week, so if you’re looking to buy a smart ring, this is the deal worth shopping.We're tracking all the best Prime Day dealsThe Tom's Guide Savings Squad is busy finding the best products for less this Prime Day!
