RingConn refreshed its smart ring line in 2026 with the Gen 3 at £309, alongside the older Gen 2 still available at £259. Both rings share the same no-subscription RingConn app and Apple Health / Google Fit integration. The price difference buys an upgraded sensor stack (multi-wavelength PPG, skin-temperature trend), a slimmer 2.5mm ring profile, and faster charging. This guide explains what's actually new in the Gen 3 and which ring is right for which user.

RingConn Gen 3

4.5 / 5
From £309
A black smart ring representing the RingConn Gen 3

Bottom line. The right pick for users who specifically want the improved SpO2 accuracy (sleep apnea screening relevance), the skin-temperature tracking, or the slimmer ring profile. The premium is justified by the sensor upgrades for users who'll use them.

Pros

  • First smart ring with built-in haptic motor (vibration alerts for elevated HR, inactivity, step goals)
  • Nighttime blood-pressure trend tracking - new metric class for the category
  • 10-14 day battery life across the category's longer-lived end
  • No subscription required - all features included with hardware
  • Universal wireless charging case (size-agnostic) replaces Gen 2's awkward size-specific charger
  • Titanium build with medical-grade epoxy interior
  • 10 ATM water resistance (shower + swim compatible)

Cons

  • £309 price closes the value gap vs Oura Ring 4 (£349 hardware) - no longer the budget no-sub pick
  • Nighttime blood pressure tracking is trend-only, not clinical-grade or medically validated
  • Haptic motor reduces battery life from 14 to 10-12 days when active
  • Independent polysomnogram + chest-strap HRV validation data not yet published (CES 2026 launch)
  • UK retail availability still building in mid-2026

RingConn Gen 2

3.9 / 5
From £259
Silver smart ring on a clean white background — RingConn Gen 2

Bottom line. The right pick for users entering the smart ring category who want the longest battery life and the lowest no-subscription price. Strong value at £259 - particularly compelling versus Oura's subscription model. Less compelling if skin temperature or the more advanced sensors matter.

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 £259 - 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

What does the Gen 3 actually upgrade over the Gen 2?

The Gen 3 upgrades fall into three categories: sensor improvements, form factor, and charging convenience.

Multi-wavelength PPG. The Gen 3's photoplethysmography array uses multiple LED wavelengths (green, red, infrared) rather than the Gen 2's single-green-LED setup. The practical difference is more reliable SpO2 measurement during sleep, when finger movement and pressure changes degrade single-wavelength readings. For users using their ring for sleep apnea screening, this is a meaningful clinical accuracy upgrade.

Skin-temperature trend tracking. The Gen 3 includes a thermistor that tracks finger skin temperature trends across nights. This is useful for menstrual-cycle phase detection (skin temperature rises around ovulation) and for illness early-warning (fever often precedes other symptoms by 24-48 hours). The Gen 2 doesn't have this sensor at all.

Slimmer ring profile. 2.5mm thick versus 2.8mm on the Gen 2 - small in absolute terms but meaningful for users with smaller fingers, for users who wear the ring during weight training, and for women who wear the ring alongside other jewellery. Reviews of the Gen 3 consistently cite the slimmer profile as a noticeable comfort improvement.

Faster charging. Gen 3 ships with a faster charging dock - ~50 minutes for full charge versus 90 minutes on the Gen 2 dock. Marginal in absolute terms but a real convenience for users who put the ring on quick charges during showers.

Is the Gen 3 upgrade worth it?

Honest framing on the upgrade decision:

Upgrade to Gen 3 if: you specifically want skin-temperature tracking (cycle tracking, illness early warning), you'll use the improved SpO2 for sleep apnea screening, the 2.5mm slimmer profile matters for comfort, or you want the latest sensor stack for longer future-proof use.

Stick with Gen 2 if: you primarily care about sleep, HRV, recovery, and activity metrics (all identical between the two), battery life matters more than sensor accuracy (Gen 2 is 10-12 days vs Gen 3's 8-10), or you want the lowest credible no-subscription smart-ring entry point at £259.

If you already own the Gen 2: the upgrade case is meaningfully weaker. The Gen 2's existing sensor stack delivers reliable sleep and recovery metrics that aren't materially worse than the Gen 3 for most use cases. The upgrade spend is better directed at a CGM sensor for two weeks of metabolic insight or saved toward a 2027-tier refresh.

How does the RingConn line compare to Ultrahuman and Oura?

At the £259-£309 RingConn price band:

vs Oura Ring 4 (£349 + £5.99/month subscription). RingConn's no-subscription model is the deciding factor for many buyers - over a 3-year ownership period, Oura's subscription adds £216 to the all-in cost. Oura's app is more mature with more research integrations; RingConn's app is simpler but functionally complete for core metrics.

vs Ultrahuman Ring Air (£329). Roughly equivalent positioning - both no-subscription rings at similar prices. Ultrahuman has a more aggressive metabolism-PowerPlugs marketing angle; RingConn has the longer battery life. The choice often comes down to app preference - both are credible options at this tier.

vs Samsung Galaxy Ring (£399). Samsung's ring is more expensive and tightly integrated with the Samsung Health ecosystem; RingConn is platform-agnostic with broader Android/iOS support. For users in the Samsung phone ecosystem, the Galaxy Ring is the natural choice; for cross-platform users, RingConn is the safer pick.

Frequently asked questions

Is the RingConn Gen 3 worth the upgrade over the Gen 2?
For users who want skin-temperature tracking or improved SpO2 for sleep apnea screening - yes, the premium buys meaningful sensor upgrades. For users primarily wanting sleep, HRV, recovery, and activity tracking - the Gen 2 delivers the same core metrics and the saving is significant. The Gen 3 is the right pick for about 30-40% of buyers; the Gen 2 is the value pick for the rest.
Do both rings work without a subscription?
Yes. Both Gen 2 and Gen 3 include all core metrics in the base hardware purchase with no subscription required. This is the main RingConn value proposition versus Oura's subscription model. The app is the same across both rings - no paid tiers, no premium features locked behind subscription.
Does the Gen 2 still get firmware updates?
Yes - RingConn has committed to continued firmware support for the Gen 2 through at least 2027, with bug fixes and minor feature improvements. Major new sensor-dependent features (skin-temperature trend, for instance) are Gen 3 hardware-exclusive and cannot be back-ported via firmware to the Gen 2.
Which ring is better for sleep tracking?
The Gen 3 has a meaningful advantage for SpO2 measurement during sleep (multi-wavelength PPG vs single-LED Gen 2). For users specifically interested in sleep apnea screening, this is a non-trivial accuracy upgrade. For users only tracking sleep stages and sleep duration, both rings perform similarly.
Can I use either ring with both iPhone and Android?
Yes - both rings work with the same RingConn app on iOS and Android, and both integrate with Apple Health and Google Fit. Platform-agnostic operation is a RingConn design priority, in contrast to the Samsung Galaxy Ring which is Samsung-ecosystem-focused.
Should I wait for a RingConn Gen 4?
RingConn's release cadence is roughly 18-24 months between generations. The Gen 3 launched in early 2026, so a Gen 4 is unlikely before late 2027 at earliest. If you want a smart ring now and the Gen 3's feature set fits your needs, buying is the right call - the next-generation wait would be a year-plus.
