Improved over previous gen. Tracking can be off
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Pro: -More comfortable than previous gen -Accurate sleep tracking -Week long battery life Con: -Almost useless without subscription -The thickness can get in the way The Oura 4 Ceramic gives a different look to the ring compared to the metal ones. It has a deep shine like it has two layers of glossiness, looking very much like a new coffee cup. While I do like the look, being ceramic, I’m concerned about its finish long term since they tend to dull over time. On the inside are sensors, increased from the previous generation. The sensors no longer protrude making it more comfortable to wear. The ring is still thicker than a typical ring and it can definitely get in the way. I wear it mostly on my middle finger and it presses into the other fingers. It can also get snagged on my pockets or hit against surfaces. The tracking is mostly accurate from what I’ve seen. It tracks activity, sleep, and body signals which it uses to present them as Readiness, Activity, and Sleep scores. The sleep tracking is very accurate and shows exactly when I wake up and the total time I’m actually asleep. The activity tracking can seem off at times. Sometimes I feel like I’m moving around more than what is tracked and other times it seems to track more than what I’m actually doing. For instance, I was just walking around the house not doing that much and it wanted to log it as an activity for over an hour. What is shown on the app’s main page can seem like it’s too simplified in some areas. On the main page, it displays your activity goal, scores, and timeline for the day. You have to go deeper in the pages to see more information. Something like steps or calorie burned should probably be on the main page. However, once you do open up each tab, there’s a lot of information and graphs giving a more detailed breakdown of the scores. Being able to see all the details can help motivate you to improve your habits. The big negative is that it requires a subscription for the tracking, and without one, it’s practically useless. Without one, it will only give you the three main scores without any other information. If you don’t want to pay a subscription, then this is not for you. The battery life lasts about a week, maybe a little less. On day six, it was down to about 25%. It also charges very quickly, maybe about 30 minutes to full charge. Whether this is worth it or not depends on the user. If you don’t like having a thick ring on all the time, or if you need tracking without the subscription, then there are other devices. If you want something smaller and more discrete then it may fit your needs. It may take some getting used to having a ring this size on all the time. From what I’ve seen so far, sleep and vital tracking are accurate, but activity doesn’t seem to be as much.

||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I find the data the ring collects very insightful, however, the ring does scratch easily. I would recommend a cover for when using it while weight lifting.
