In short
Get RingConn Gen 2 if you find one in stock: it's slimmer than Gen 3, at 2.0mm and 2 to 3 grams, with sleep-apnea monitoring and no subscription. It lasts 10 to 12 days by size; RingConn claims up to 150 days with its charging case. It was listed from $299 but out of stock on 19 September 2026. Gen 3 adds vibration alerts and size 15; Gen 2 Air costs $199 without apnea monitoring.
Who it is for
- Anyone who wants a slim titanium ring with no subscription. Gen 2 is 6.8mm wide, 2.0mm thick and 2 to 3 grams.
- People who want sleep-apnea monitoring, which RingConn lists for Gen 2 but not for Gen 2 Air.
- Gen 2 Air owners who already know their size. The two rings share sizes 6 to 14 and one sizing kit.
Who should skip it
- Anyone who needs a ring this week. RingConn's own store had Gen 2 out of stock on 19 September 2026.
- Anyone who wants vibration alerts, vascular-health trends or a size 15. Those are Gen 3 features.
- Tighter budgets that can do without apnea monitoring. Gen 2 Air costs $199 against Gen 2's $299.
- Oura members who want to keep Oura's membership scores. Gen 2 runs on RingConn's own app.
What sets it apart
- Slimmer than Gen 3: 2.0mm and 2 to 3 grams, against 2.3mm and 2.5 to 3.5 grams.
- Sleep stages (REM, light and deep), naps and sleep-apnea monitoring, with no subscription fee.
- 10 to 12 days per charge, depending on ring size.
- A wireless charging case cut to your ring size comes in the box, and RingConn claims up to 150 days of use with it.
Caveats
- Turning on sleep-apnea monitoring may shorten battery life, RingConn says.
- The case fits only your ring size and isn't sold separately; a replacement comes as a charging dock.
- The RingConn app links one ring to an account at a time.

Where Gen 2 sits between Gen 2 Air and Gen 3
Gen 2 was RingConn’s flagship before Gen 3, and RingConn’s comparison page still lists it beside both.
Against Gen 3, it’s the slimmer and lighter ring, but it has no vibration motor, no vascular-health trends and no size 15. Gen 3 also brings a universal charging case and a sizing system of its own.
Against Gen 2 Air, Gen 2 is the pricier ring, and the difference buys titanium in place of Air’s stainless or titanium steel, plus sleep-apnea monitoring. RingConn Gen 2 vs Gen 3 and Gen 2 vs Gen 2 Air compare them in full.
Battery and charging
Smaller rings get less battery: sizes 6 and 7 are rated for 10 days, and only sizes 12 to 14 reach 12. The ring charges magnetically in about 90 minutes.
Gen 2 stores 5 to 7 days of data offline (RingConn’s comparison says 7), so sync it with your phone about once a week.
Sleep and health tracking
Gen 2 tracks REM, light and deep sleep and naps, and it watches for signs of sleep apnea, which Gen 2 Air doesn’t. RingConn claims 90.7% accuracy for apnea monitoring; that’s RingConn’s own figure, so treat the results as wellness tracking.
Around the clock it reads heart rate, HRV, blood oxygen and temperature, and it counts steps, calories and workouts in the RingConn app.
Price and stock
RingConn listed Gen 2 from $299 on 19 September 2026 but showed it out of stock, so a new one may take some hunting. If you find one near that price, you get the slim titanium ring with apnea monitoring; if not, Gen 3 is RingConn’s current model.

Frequently asked questions
Is there a subscription fee for RingConn Gen 2?
No. RingConn lists no subscription fee for Gen 2, so there's nothing more to pay after the ring.
Does Gen 2 work with an iPhone?
Yes, on iOS 17 or later. Android phones need Android 10 or later, and either way the phone needs Bluetooth 4.0 or above.
Is Gen 2 the same size as Gen 3?
No. Gen 3 uses a different sizing system, so measure again with a Gen 3 kit. Gen 2 shares its sizes and kit only with Gen 2 Air.
Does Gen 2 diagnose sleep apnea?
No. It's sleep-apnea monitoring for wellness, not a clinical test. RingConn doesn't repeat for Gen 2 the not-a-medical-device statement it gives Gen 3, and it doesn't mention FDA clearance.
