Oura Ring 5 Size 12 Stealth

Super beautiful design. A slimmer model, and it really shows. It looks less like a smart ring and more like a normal piece of jewelry. It measures an incredible amount of things. The app is somewhat difficult, so it takes a little while to figure out everything you can read. But I think it's really worth the price. The battery really lasts 7+ days.

I have had an Oura before. The 5 fits better, looks better, and provides even more insight. For me, insight into sleep, stress, and the combination with another app is the most important thing. You get extensive insight into your sleep duration, sleep phase, heart rate, HRV, stress/rest, and calorie consumption (based on activity). There are also other options that only become visible after longer use (such as sleep chronotype).

Activities such as steps, cycling, walking, etc., are automatically detected.

The ring is waterproof, so you can wash your hands, shower, and do the dishes with your ring without worry.

The only downside I experience is that short interruptions during the night are not visible. You do see moments of movement during the night, though. However, it does not detect being awake briefly, which makes you tired in the morning. As a result, my sleep score is higher; I think that is how it is supposed to be. If I get up or stay awake longer, the ring does detect it. Also, if I watch TV in bed, that is sometimes considered light sleep. You can manually adjust your bedtimes (falling asleep and waking up) in the app.

It tracks a lot and is super accurate. It isn't just a simple pedometer and heart rate monitor, but does so much more. The app does have monthly costs, which is a shame, but it is secretly worth it. And on top of that, it looks like a regular piece of jewelry. In short, I am very happy with it.
