Gen 2 is the thinner leftover RingConn: 2.0 mm / 2–3 g, 10–12 days, no sub, sleep-apnea monitoring, from $299 — but the page was out of stock on 2026-09-19.

In short

Gen 2 is the thinner leftover RingConn: 2.0 mm / 2–3 g, 10–12 days, no sub, sleep-apnea monitoring, from $299 — but the page was out of stock on 2026-09-19. Buy it if you find stock and want the slimmer sleep-first ring. Skip it if you want Gen 3 vibration / vascular trends / size 15, or if checkout is empty.

Who it is for

  • No-sub buyers who want the thinner 2.0 mm / 2–3 g titanium ring.
  • People focused on sleep stages + Gen 2 apnea monitoring (compare: Yes; Air: No).
  • iOS 17+ or Android 10+ users who already know a Gen 2 size (kit shared with Gen 2 Air).
  • Shoppers who want the 150-day case claim and a size-specific wireless case.

Who should skip it

  • Anyone who needs guaranteed US stock today — the product page was Out of stock on write day.
  • Buyers who want vibration health alerts, vascular trends, or size 15 — that is Gen 3.
  • People seeking a diagnostic apnea device. Quote RingConn’s non-medical posture from the Gen 3 footer / compare context; do not invent FDA language.
  • Oura members who want membership scores on iOS and Android.

Key differentiators

  • Thinnest RingConn flagship on the compare page: 2.0 mm / 2–3 g vs Gen 3 2.3 mm / 2.5–3.5 g.
  • 10–12 days size-banded (6–7: 10 d, 8–11: 11 d, 12–14: 12 d). Case “up to 150 days.”
  • No subscription (compare page).
  • Sleep-apnea monitoring Yes vs Gen 2 Air No.

Caveats

  • Out of stock on the official product page 2026-09-19. Leftover, not a promise of cart.
  • Gen 2 sizing is not Gen 3 sizing.
  • Enabling OSA monitoring may increase power use (Gen 2 FAQ).
  • No hands-on testing. 90.7% apnea-accuracy marketing on the product page is an OEM claim — we do not treat it as our lab.

Frequently asked questions

Can I buy Gen 2 in the US today?

The official product page showed Out of stock on 19 September 2026. Re-open ringconn.com before promising a cart.

Is there a subscription?

RingConn’s compare page lists no subscription fee.

Is Gen 2 the same size as Gen 3?

No. Gen 3 uses a different sizing system. Gen 2 shares a kit with Gen 2 Air only.

Does Gen 2 diagnose sleep apnea?

RingConn markets sleep-apnea monitoring and a 90.7% accuracy figure. That is manufacturer language, not a clinical diagnosis and not our test. Do not upgrade it to medical advice.
