A reviewer at Tom's Guide wore both the Oura Ring 5 and an Apple Watch to bed this year, sometimes at the same time. The finding: the ring gives a more detailed look at your night, while the watch is easier on the wallet if you want one anyway. The ring starts at $399.99. The Apple Watch Series 12 starts at $389.99.
What each one costs
The Oura Ring 5 launched in May 2026. The price rises to $499.99 for the Gold or Deep Rose finish. A $10 sizing kit comes first, so you can order the right fit. Membership is $5.99 a month, with the first month free. The ring is rarely discounted, though Black Friday sales may change that.
The Apple Watch Series 12 launched in September 2026 and has no subscription. It has been seen on sale for $379, so holiday deals may bring that price back. The older Apple Watch SE 3 is $239.99, which saves more than $100.
How the sleep tracking differs
Both devices show sleep stages (REM, deep and light), sleep consistency, overnight heart rate, breathing rate, body temperature and a daily score out of 100. You can see it all in each app when you wake up.
The difference is depth. Apple builds its sleep score from three things: interruptions, duration and bedtime. Oura uses seven, including how long you take to fall asleep, how restless you were and the timing of your sleep. Oura also offers a Readiness score and a Body Clock feature that looks at how your routine fits your natural rhythm.
The reviewer found it easier to reach scores in the 90s on the Apple Watch, and took that as a sign the Oura scoring is more demanding and detailed.
What the watch does well
Apple's standout sleep feature is sleep apnea detection, available on the Apple Watch Series 10 and newer. It looks at breathing patterns and alerts you if it sees a lot of disturbances, which could point to sleep apnea, a condition where breathing repeatedly stops during sleep.
Comfort and what is unclear
Comfort matters because you wear these all night. The reviewer wore an Apple Watch Ultra, which is large and thick, and said it took time to get used to. Newer models are described as a better fit, but the text provided cuts off before the full comfort comparison and a final verdict.
The takeawayIf you want the most detailed sleep data, the Oura ring fits, but add $5.99 a month. If you want a watch anyway, the Apple Watch has no fee.
