The verdict

RingConn Gen 2 Air is a $199 titanium-steel ring that tracks sleep stages, heart rate, HRV, SpO2 and skin temperature. RingConn lists the subscription fee as free, so there's nothing more to pay each year. The catch: it lacks the Gen 2's sleep apnea monitoring, and returns need a valid reason such as a defect.

The trade-off

It has no sleep apnea monitoring or charging case, and RingConn takes returns within 14 days only for a reason such as a defect or the wrong color.

About this price

Galaxy Silver was $199.00 in every size from 6 to 14 on RingConn's US product page on Oct 13, 2026, and so was the 'Don't know my size' option. The page labels it 'Sale price $199.00 USD' but shows no regular or strikethrough price. RingConn's online store gives a regular price of $199.00, equal to the price, for every option. So $199 counts here as the list price, not a discount. Dune Gold was also $199.00. The price is before tax and shipping, and the product page doesn't state a shipping cost. The trade-in offer ('Save up to $40.00 on your new ring') and HSA/FSA payment through Flex aren't deducted.

THINK TWICE IF

Anyone who wants sleep apnea monitoring, which the FAQ says Gen 2 Air doesn't include
Anyone who might change their mind, since returns need a valid reason such as a defect, damage or the wrong color
Anyone who wants a portable charging case: Gen 2 Air ships with a wired dock instead
Anyone who plans to wear it in a sauna: the working temperature RingConn lists tops out at 104°F (40°C)
Anyone whose phone runs something older than iOS 17.0 or Android 10.0

What still needs checking

Which sensors the ring uses, since the page doesn't list them
Independent, peer-reviewed accuracy data for Gen 2 Air against polysomnography, ECG or pulse oximetry
Whether RingConn counts a poor fit as a valid reason for a return or exchange
Shipping cost, which the Gen 2 Air page doesn't state
Battery lifespan, out-of-warranty repair or battery cost, and the dock's power draw
Whether RingConn regards Gen 2 Air as a medical device, since the product page doesn't say
How long RingConn will keep the app's features free and keep supporting Gen 2 Air

The practical details.

Specifications for RingConn Gen 2 Air
Exact variant	Galaxy Silver, sizes 6 to 14 (or 'Don't know my size' with the free sizing kit), charging dock included
Battery life	Up to 10 days on a full charge, depending on ring size. Magnetic charging on the included wired dock takes about 90 minutes to full. Unlike the Gen 2, it comes with a dock, not a charging case
Sensors and metrics	The page doesn't list sensor types. The FAQ says the ring continuously monitors heart rate, SpO2, body temperature, sleep, steps and exercise calories. Its comparison table shows 24/7 HRV and skin temperature too. The page also covers sleep stages, workouts, a Stress Score and cycle predictions. The FAQ says it doesn't include sleep apnea monitoring
Subscription	None. The page's comparison table lists the Gen 2 Air subscription fee as 'Free'
FDA clearance	None claimed. The product page makes no FDA claim and doesn't say whether the ring is a medical device
Sizes and weight	Sizes 6 to 14, plus 'Don't know my size' with a free sizing kit. 6.8 mm wide, 2 mm thick, 2.5 to 4 g. RingConn says Gen 2 and Gen 2 Air share the same sizes and sizing kit
Water resistance and operating range	IP68, to 100 m (328 ft). Working temperature 32°F to 104°F (0°C to 40°C)
Data and compatibility	Stores 5 to 7 days of data offline. The ring uses Bluetooth 5.0. It works with iOS 17.0 or later and Android 10.0 or later, on phones with Bluetooth 4.0 or above. The FAQ says data transmission, storage and analysis are encrypted and processed on AWS servers in the UK
US import status	Not barred. An August 2025 US International Trade Commission (ITC) order barred imports of RingConn rings that infringe an Oura patent. RingConn then settled with Oura and licensed the patent, so in December 2025 the ITC removed RingConn from the order
Dimensions	6.8 mm wide and 2 mm thick, weighing 2.5 to 4 g depending on ring size. RingConn's page doesn't give the inner diameter of each size.
Materials	Titanium steel with a PVD coating and medical-grade epoxy resin. The FAQ contrasts this with the titanium used for the Gen 2.

Before you buy

InstallationNo installation

No installation. If you don't know your size, choose the free sizing kit ('Don't know my size') when you order. RingConn says it sends the kit before the ring ships, and that it arrives in 3 to 8 days, depending on location. It suggests wearing the sizing ring for at least 24 hours, including overnight, then submitting your size under 'My Orders'. If you're between sizes, it recommends the smaller one or sending RingConn photos and videos. The ring works with iOS 17.0 or later and Android 10.0 or later. Each account pairs with one ring at a time. In the box are the ring, a charging dock, a Type-C cable, and an instruction manual and quick start guide.

WarrantyRingConn's Return & Refund Policy gives one year from delivery…

RingConn's Return & Refund Policy gives one year from delivery outside the EEA, which includes the US, and two years in EEA countries. It will repair, replace or refund if a defect in its workmanship causes the damage. Claims go to RingConn with proof of purchase. The warranty excludes improper or negligent use, maintenance contrary to instructions, normal wear and tear and accidental damage. The policy calls rechargeable batteries consumables with a limited lifespan and leaves battery replacement out of the standard warranty. The warranty transfers to later owners. The Gen 2 Air page itself carries no warranty text.

ReturnsOnly rings bought directly from RingConn.com qualify

Only rings bought directly from RingConn.com qualify. You have to request a return within 14 calendar days of delivery, and you need a valid reason. The policy lists a defect or damage on delivery, a color that doesn't match your order, or a product that differs significantly from its description. The ring must be in its original condition, unopened and unused. Once a return is approved, you have 14 days to send it back. You pay return shipping, and shipping, handling and tax aren't refunded. The exception is a defect, damage or non-conformity you reported with photos in advance. No restocking fee is stated, but RingConn may deduct for damage, wear or missing parts. Refunds go to the original payment method within 30 calendar days of RingConn receiving the ring or proof of return, whichever comes first. Sizing kits can't be returned, and canceling after the kit ships costs $10. For a different size or color, the policy recommends returning the ring and placing a new order.

More about this assessment

RingConn Gen 2 Air is a titanium-steel smart ring that costs $199 in every size and both colors. RingConn lists the subscription fee as 'Free', so there's nothing more to pay each year. It monitors heart rate, SpO2, HRV and skin temperature around the clock, with up to 10 days of battery. Unlike the $299 Gen 2, it has no sleep apnea monitoring and comes with a wired dock, not a charging case. Returns within 14 days need a valid reason such as a defect, and the 1-year US warranty excludes battery replacement. No independent accuracy study of Gen 2 Air was found, so its readings are unconfirmed.

Energy component: Unknown

Purchase + installation + years × (annual consumables + annual other) + watts/1000 × hours/day × 365 × years × $/kWh. Annualized allowances, not an exact replacement schedule. Excludes taxes, shipping, finance and resale unless entered.

Replacement parts & cost assumptions

No scheduled consumable is listed. That does not mean zero maintenance or repair costs.

The estimate uses $199, the list price for Galaxy Silver in every size on RingConn's US store. The comparison table lists the subscription fee as 'Free', so other annual costs are $0. The three-year estimate is $199 + 3 × ($0 + $0) = $199 before tax and shipping, plus charging energy, which is unknown.
Nothing needs regular replacing: the charging dock and Type-C cable come in the box, and RingConn lists no refills for the ring. So annual consumables are $0. That doesn't make battery wear, a lost ring or an out-of-warranty repair free. The policy excludes battery replacement from the standard warranty and gives no battery lifespan or replacement price.
RingConn doesn't state the dock's power draw, so energy is unknown. With up to 10 days per charge and about 90 minutes to recharge, expect to charge it a few times a month.
The page says RingConn is HSA/FSA eligible through Flex and advertises a trade-in credit of up to $40. Neither is deducted here.

Evidence & sources.

How accurate are sleep trackers? Our evidence review grades the research as Moderate. That grade is about the claim, not about this product.

Manufacturer claimPrice, colors, sizes, tracked metrics, battery life, charging, storage, dimensions, materials, water resistance, compatibility and the 'Free' subscription fee all come from RingConn's own product page and online store.^{1, 2} Not independent testing. The regular price comes from RingConn's online store. Warranty and return terms come from RingConn's Return & Refund Policy.
Manufacturer claimRingConn claims no FDA clearance or authorization for Gen 2 Air. The product page doesn't say whether the ring is a medical device. It frames the health features as 'AI-powered insights for proactive wellness'.¹ No FDA database search was done for this review. Treat the readings as wellness trends, not diagnostic measurements.
Manufacturer claimThe page says the ring predicts periods 'with high accuracy' and that the index finger gives stronger arterial blood flow for better measurement precision. It also says accuracy stays consistent on the index, middle or ring finger, and warns that the wrong size may affect sensor accuracy.¹ The page cites no study or accuracy figure for any metric. No independent validation study of Gen 2 Air was found for this desk review, so its accuracy for sleep, heart rate, HRV, SpO2 and temperature is unconfirmed.
Regulator recordThe US International Trade Commission's December 2025 notice says RingConn licensed a group of patents from Oura in a settlement, including the patent behind the import ban. The ITC then removed RingConn from its limited exclusion order and rescinded the cease and desist orders against RingConn.⁴ The settlement agreement was served only on Oura, RingConn and ITC staff, so its terms aren't public.
