Oura Ring Gen 4 Review: The Wearable You Actually Forget You're Wearing
After six months with the Oura Ring on my finger, here's what the health data actually told me — and what it couldn't.
Six months ago I put an Oura Ring on my right index finger and largely forgot it was there. That's both its biggest strength and the most interesting thing about it — you don't interact with it the way you interact with a smartwatch. It just watches.
What the Data Actually Showed Me
The sleep staging accuracy is legitimately impressive. I was skeptical of consumer-grade sleep tracking — I still am, about most devices — but comparing Oura's readings against a friend's clinical sleep study data from the same nights showed correlations I didn't expect. Deep sleep percentages were within 8-12% of the clinical measurements. Not perfect, but genuinely informative.
The more useful insight, for me personally, was readiness scoring. On mornings when I woke up feeling fine but the ring showed low readiness, I'd dial back my workout intensity. Three times over six months, doing so clearly helped me avoid overtraining symptoms I'd had in the past. Correlation, not causation — but I've changed my behavior based on it.
The Subscription Problem
Here's the part that annoys me: the Oura Ring costs $299-$549, and then you need a $5.99/month subscription to access most of the health insights. Without the subscription, you get basic step and sleep data. With it, you get the full readiness scores, trend analysis, and cycle insights. It's not unreasonable money, but the principle of charging a premium hardware price and then locking the useful features behind a subscription rubs me wrong.
Who It's For
People who want health tracking without the screen fatigue of a smartwatch. People who wear rings already and won't find it intrusive. Athletes who want recovery data. Anyone curious about their sleep quality. It's not for people who want real-time notifications or GPS tracking — this is a sensor, not a smart assistant.
