Before buying any sleep tracker, read our honest breakdown of what these devices measure well versus poorly — sleep stage data (light/deep/REM) agrees with clinical sleep studies only about 60-70% of the time across all consumer wearables, this list included.
The short version
RingConn Gen 2 Air is the no-subscription alternative to Oura — a smart ring with lifetime access to standard features included in the $199 purchase price, at 4.1 stars across more than 2,400 ratings.
What it actually is
Per the manufacturer’s listing:
- No subscription fee for standard features — the core differentiator versus Oura’s $5.99/month
- 2mm profile, 2.5g weight — thinner than Oura, per the listing
- Up to 10 days battery life, 90-minute full charge
- IP68 waterproof to 100m, tracks sleep, heart rate, stress, blood oxygen, activity
Who it’s a good fit for
Anyone who wants ring-form tracking like Oura’s but doesn’t want an ongoing monthly cost — $150 cheaper upfront than Oura Ring 4, with no subscription for the core features most people actually use.
Where it’s probably not the right pick
Smaller review base and brand recognition than Oura — if the specific “AI Advisor” and 50+ metrics Oura tracks matter to you specifically, Oura Ring 4 has a longer track record.
Bottom line
The best value in this roundup for ring-form tracking — nearly the same core functionality as Oura without the recurring subscription.
