RingConn Gen 2
Value-priced smart ring with no subscription, 10–12 day battery, charging case included — the cheapest credible Oura alternative in 2026.
3.9 / 5
☆☆☆☆☆
★★★★★
Pros
- No subscription — every feature is included with the hardware purchase, the same value proposition as Ultrahuman at a lower price
- 10 – 12 day real-world battery life is roughly double the rest of the category and a meaningful difference for daily wearers
- Portable charging case ships in the box and provides multiple top-ups without finding the puck — travel-friendly
- Genuinely competitive entry price at £239 / $279 — undercuts the Oura Ring 4 (£349) and Ultrahuman Ring Air (£299) on hardware alone
- Three understated finishes work as either a smart ring or a passable everyday ring; the form factor is one of the slimmer profiles in the category
Cons
- Sleep-stage and HRV algorithms are visibly less refined than Oura's and slightly behind Ultrahuman's in independent comparisons
- 5 ATM water resistance is fine for showering and shallow swimming but trails Ultrahuman and Oura's 10 ATM rating for water sports use
- App is functional rather than polished — fewer narrative insights, more raw-number dashboard than the Oura or Ultrahuman experiences
- Smaller brand with less long-term financial visibility than Oura — buyers should account for the residual support risk over a multi-year ownership horizon
- Limited third-party integrations and a closed ecosystem similar to rivals — historical data effectively lives in the RingConn app
