RingConn Gen 2 vs Oura Ring 4 vs Galaxy Ring: The Subscription Math

Here is the number that settles most smart ring decisions before any sensor comes into it. Over three years an Oura Ring 4 costs about $560: $349 for the ring, then $5.99 a month after the first month. The Galaxy Ring costs $399 and nothing after that. The RingConn Gen 2 costs $299, also with nothing after that.

All three read the same basic signals from your finger: heart rate, HRV, blood oxygen, and skin temperature, with sleep staged overnight and summarised in the morning. So the question isn't which one can track your sleep, because they all can. It's whether Oura's app is worth roughly $260 more than the RingConn over three years, and whether your phone lets you choose the Galaxy Ring at all.

Your Phone Removes One Option First

The Galaxy Ring works only with Android, and its best features need a Samsung phone. With an iPhone, your choice is between Oura and RingConn. With a Galaxy phone, the Galaxy Ring is the obvious way to avoid a subscription, because it feeds Samsung Health with everything else your phone and watch already record. Its Energy Score, which combines sleep and activity into one daily number, is the headline feature.

With any other Android phone, the Galaxy Ring still pairs, but you'd be paying $399 to get less than the RingConn gives you for $299.

What $5.99 a Month Buys at Oura

Oura calls the subscription required, and in practice it is. Without it you keep the three daily scores, Sleep, Readiness, and Activity, but lose the detail underneath them: what drove each score, the long-term trends, and the AI coach. What you're paying for is the most mature sleep model in the category. Oura has the deepest body of independent validation against polysomnography of any consumer ring, and its staging has held up well in those studies (de Zambotti et al., 2019; Altini & Kinnunen, 2021). Overnight HRV and skin temperature from the finger are where rings do best, because the finger gives a strong signal and you move little while you sleep.

Oura is also the best built of the three: titanium, 10 ATM, 4.5 g, eight days per charge, and an app that ties it all together. If you want a ring you'll forget you're wearing and a morning score you'll trust, Oura is still the benchmark, and the subscription is the price of that.

Oura has since released the Ring 5: 40% smaller, six to nine days per charge, and $50 more at $399, on the same membership. The Ring 4 is still sold, now discounted in several finishes, so the math here holds for either.

What the RingConn Gen 2 Does Differently

The RingConn Gen 2 is cheaper up front and costs nothing after that, but two features are the real reasons to pick it.

Sleep apnea monitoring. It's one of the few rings that watches for breathing disturbances overnight. RingConn applied for FDA clearance but hasn't received it, so treat the output as a prompt to talk to a doctor, not a diagnosis. That still matters, because obstructive sleep apnea is common and mostly undiagnosed (Benjafield et al., 2019). If you snore, wake up unrefreshed, or score high on the Epworth sleepiness scale, a ring that flags a pattern is useful.

The charging case. The Gen 2 comes with a case that holds extra charge, like earbuds do. You top up the ring from the case and charge the case now and then. Combined with ten to twelve days per charge on the ring itself, that makes it the easiest of the three to live with on the road.

The trade-offs are real. The app is less polished than Oura's, sleep staging is still maturing, and it has no workout integration worth using. Water isn't one of the trade-offs: like the other two, it's rated to 100 m.

The Three Side by Side

Three-year cost counts the ring plus any required subscription over 36 months, with Oura's first month free. Weights are for the ring alone and vary by size. Green marks the best in a row, shared when it's a tie.

The full spec sheets are on the RingConn Gen 2, Oura Ring 4, and Galaxy Ring pages. The wearables comparison tool puts any of them next to a watch or band.

Should You Wait for the Gen 3?

You don't have to wait, because the RingConn Gen 3 is already out, at $349 to $369. It lasts eleven to fourteen days and is the first RingConn with a vibration motor, used for heart rate, inactivity, and battery alerts rather than notifications. Its charging case is universal, so it fits every RingConn ring and size. It also adds Vascular Health Insights, which shows overnight trends related to blood pressure after you calibrate it with a cuff. It doesn't give you a blood pressure reading. There's still no subscription.

If vibration alerts or a couple more days per charge matter to you, the extra $50 buys both. If not, the Gen 2 is the better value, and it's the one we'd buy for an iPhone owner who won't pay Oura's subscription. On a tighter budget, the Gen 2 Air is $199, but it drops the charging case and the sleep apnea monitoring, which are the two best reasons to buy a RingConn.

Choosing

Choose Oura if the sleep and readiness scores are the reason you want a ring and you're comfortable paying about $72 a year for the best-validated version of them. Choose the Galaxy Ring if you have a Samsung phone and want everything in Samsung Health without a subscription. Choose the RingConn Gen 2 if you want a ring without a subscription on an iPhone, or if sleep apnea screening is part of the reason you're buying.

Whichever you choose, the scores are estimates with real error bars, and consumer sleep trackers are good at duration and timing but weaker at telling light sleep from deep sleep (Chinoy et al., 2021; Stone et al., 2020). Use the trend, not a single night. And before paying anyone to score your sleep, get the basics right: a consistent schedule planned with the sleep calculator will do more than any ring. Our sleep optimization guide covers the rest. If you're also weighing Oura against a wrist band, we compared Oura Ring 4 vs Whoop 5 separately.
