Oura Ring 5 vs RingConn Gen 3

On paper these two look alike: titanium bands of about the same thickness, both rated to 100 meters, both tracking sleep and heart data through a phone app. Ring 5 dates from 28 May 2026, and Gen 3 was still RingConn’s newest ring that September. The differences are in what you pay over time, how often you charge, and a small motor inside the RingConn.

One price, or a price plus a plan

RingConn Gen 3 starts at $349, and RingConn’s compare page lists no subscription, so the app doesn’t hold features back for a fee. Oura Ring 5 starts at $399, and Oura Membership costs $5.99 a month or $69.99 a year once a new member’s free month runs out. Membership is attached to your account, so it moves with you to a new Oura.

Skip it, and Ring 5 still collects data, but the app holds you to three daily scores and the basics. Everything past that, from detailed sleep and blood oxygen to 24/7 heart rate, stress, heart health and women’s health, needs the membership. Oura’s newer software, Health Radar among it, runs on Gen3 and later Oura rings rather than on Ring 5 alone, and RingConn has nothing by that name.

Battery, charging and memory

Battery is where Gen 3 pulls clearly ahead. RingConn’s claim is 10 to 12 days with the vibration motor running and 11 to 14 days without it, and its compare page says up to 14. Oura’s figure for Ring 5 is typically 6 to 9 days, and it moves with ring size, your settings, how active you are and the battery’s age. The two companies test differently, but the bottom of RingConn’s range still sits a day past the top of Oura’s.

Ring 5 charges in about 80 minutes on a size-specific dock that comes in the box with a USB-C cable; you supply the power adapter. Ring 5’s charging case is sold on its own; Oura rates it at up to a month of charging, with a full day’s worth after roughly 10 minutes. Gen 3 charges in RingConn’s universal wireless case, which works with other RingConn rings too; the case itself takes about 120 minutes to charge. A Gen 2 case can also charge Gen 3 if the size fits.

If you go a while without opening the app, Gen 3 holds 10 days of data offline. Ring 5 holds up to 3.

Fit and finish

Both start at size 6, but Gen 3 continues to 15 while Ring 5 stops at 13. Each has a sizing kit of its own that doesn’t carry over from the brand’s older rings: Ring 5 uses white sizers rather than the Ring 4 kit, and Gen 3 has its own kit rather than Gen 2’s.

Thickness is a wash, 2.28 millimeters for Ring 5 against 2.3 for Gen 3. Ring 5’s band is 6.09 millimeters wide, with a sensor dome that rises 0.7 millimeters, but RingConn doesn’t give Gen 3’s width, so there’s no telling which sits wider on your finger. Gen 3 weighs 2.5 to 3.5 grams and Ring 5 starts at 2; Oura also says Ring 5 is 40 percent smaller by volume than Ring 4.

The materials differ more than the measurements. Ring 5’s shell is all titanium under a superhard PVD coating, while Gen 3 combines titanium with medical-grade epoxy and PVD. Oura offers six finishes; RingConn offers three: Polished, Brushed and Matte.

Alerts and health trends

Gen 3’s vibration motor nudges you with health alerts and reminders, but it won’t buzz for a text or an alarm. Its sleep tracking adds a sleep apnea pattern or risk indicator, and its vascular health feature is a nighttime trend built from patterns, habits and things you enter yourself. Neither is a diagnosis: the indicator isn’t a sleep study, the vascular trend isn’t a blood-pressure reading, and RingConn says Gen 3 isn’t a medical device. RingConn’s FAQ counts respiratory rate as 24/7, while its compare page lists it with the nighttime readings.

For sensors, RingConn lists optical heart rate, temperature and a 3-axis accelerometer, against Ring 5’s pair of triple LEDs and pair of photodetectors plus temperature and motion sensing. Ring 5 recognizes 40-plus activities on its own, but that’s activity detection, not GPS, and neither ring is a GPS sports watch. Oura’s store also quotes accuracy percentages, which are Oura’s own figures, and Oura’s legal line is that Ring 5 isn’t intended to diagnose, treat, cure, monitor or prevent medical conditions.

Phones, water and temperature

Check your phone first. Gen 3 needs iOS 17 or later, or Android 10 or later. Ring 5 needs iOS 16 or later, or Android 11 or later with Google Play, plus Bluetooth 5.0 on the phone. An iPhone that can’t update past iOS 16 works with Oura but not RingConn, and an Android 10 phone is the other way round.

Each claims 100 meters of water resistance. RingConn adds IP68 and ATM10 but gives no scuba rule or time limit. Oura’s own advice varies by document: its Ring 5 guidance allows the sauna and water sports but not diving, while its general FAQs, updated 18 September 2026, allow showers, swimming and recreational diving or snorkeling, rule out scuba, and set a 12-hour limit on time underwater.

Gen 3 is rated to work from 0 to 40 °C. Ring 5 covers −10 to 54 °C by Oura’s Ring 5 guidance, or −10 to 52 °C by its general FAQs, and Oura wants it charged at room temperature.

Prices

On 19 September 2026, Gen 3 started at $349, against $399 for Ring 5 in Silver or Black and $499 for Brushed Silver, Deep Rose, Gold or Stealth. Oura’s store switched to euro prices at points that day, so make sure you’re paying in dollars. After the free first month, each year on Oura’s annual plan adds $69.99. Check both carts before you order.
