In short
Get RingConn Gen 2 Air if you want the cheapest RingConn: $199 for sleep stages and 24/7 vitals with no subscription, but no sleep-apnea monitoring. It's 2mm thick in titanium steel, weighs 2.5 to 4 grams and lasts up to 10 days, charging on a wired dock instead of in a case. RingConn showed it out of stock on 19 September 2026. Gen 2 adds titanium, apnea monitoring and a charging case for $299.
Who it is for
- Budget buyers who want sleep stages and around-the-clock heart rate, HRV, blood oxygen and skin temperature without a subscription.
- Anyone who already knows their Gen 2 size. Air uses the same sizes, 6 to 14, and the same sizing kit.
- People who'd rather charge on one dock that fits every size than in a case made for a single ring.
Who should skip it
- Anyone who wants sleep-apnea monitoring. RingConn's comparison gives it to Gen 2 and Gen 3, not to Air.
- Anyone who wants vibration health alerts, vascular-health trends or a size 15. Gen 3 has them, from $349.
- Shoppers who need a ring right away: RingConn's store had Air out of stock on 19 September 2026.
What sets it apart
- RingConn's cheapest ring: $199, against $299 for Gen 2 and from $349 for Gen 3.
- The same 2mm thickness as Gen 2.
- Up to 10 days per charge, with no subscription fee.
- Water resistant to 100 m (328 ft), rated IP68.
Caveats
- Heavier than Gen 2 at the same thickness: 2.5 to 4 grams of titanium steel, against Gen 2's 2 to 3 grams of titanium.
- RingConn describes the metal two ways: titanium steel with a PVD coating in its specifications and FAQ, stainless steel on its comparison page.
- There's no case for charging on the go, and you can't add Gen 2's, because RingConn doesn't sell it separately.

Where Air sits in RingConn’s line-up
Air is the low-cost half of the Gen 2 family. It keeps Gen 2’s thickness and sizes at a lower price, but changes the metal and the charger and drops sleep-apnea monitoring:
| Spec | Gen 2 Air | Gen 2 |
|---|---|---|
| Price at RingConn | $199 | $299 |
| Metal | Titanium steel | Titanium |
| Thickness | 2.0 mm | 2.0 mm |
| Weight | 2.5–4 g | 2–3 g |
| Battery | Up to 10 days | 10–12 days, by size |
| Charger | Wired dock, fits all sizes | Size-specific case, up to 150 days claimed |
| Sleep-apnea monitoring | No | Yes |
| Sizes | 6–14 | 6–14, same kit |
Gen 3 sits above both, from $349, with vibration alerts, vascular-health trends, a size 15 and a universal case. RingConn Gen 2 vs Gen 2 Air and Gen 2 Air vs Gen 3 cover the full specs.
Battery and charging
RingConn rates Air for up to 10 days, depending on ring size, with no size-by-size breakdown. It charges magnetically on the dock in about 90 minutes. The ring holds 5 to 7 days of data offline (RingConn’s comparison says 7), so a few days away from your phone won’t cost you any readings.
What it tracks
Air reads heart rate, HRV, blood oxygen and skin temperature around the clock, and it logs sleep stages, steps, calories, workouts and VO2 Max. There’s no vibration motor, so nothing buzzes on your finger. Treat the numbers as wellness tracking rather than medical readings.
RingConn Partner AI is available only by application, through RingConn Lab.
App and price
Air runs on the RingConn app, which links one ring per account at a time, and connects to your phone over Bluetooth 5.0.
RingConn listed Air at $199.00 on 19 September 2026 but showed it out of stock. If it stays that way, Gen 2 at $299 is the nearest step up.
