In short

Gen2 is the last no-membership Oura: night-only IR HR, discontinued hardware, firmware frozen at 4.0.8 (18 October 2022). Keep it if you already own one and refuse a subscription. Do not buy one as a new US retail SKU — Oura no longer sells it.

Who it is for

  • Owners who already have Balance or Heritage Gen2 and want an OEM-cited sheet.
  • People who will not pay Oura Membership — Gen2 is the generation Oura exempts.
  • Night-sleep-first users who accept no daytime optical HR.
  • Anyone documenting why a used Gen2 cannot run Gen3+ scores.

Who should skip it

  • Anyone shopping a new Oura. Official: Gen2 ring and charger are no longer for sale.
  • Buyers who want 24/7 HR, SpO2, Stress, or Heart Health — those need Gen3 or newer plus membership.
  • People who need published width / thickness / weight / typical-days — Oura omitted those on Previous Generations and the current FAQ battery table.
  • Shoppers expecting current firmware. Latest listed Gen2 build is 4.0.8 (18 October 2022).

Key differentiators

  • No Oura Membership and no membership fees (Membership support, 8 September 2026).
  • Night-only IR HR / respiratory rate — not the Gen3 green+red daytime stack.
  • Balance and Heritage bodies; finishes Stealth, Black, Silver, Gold.
  • Oura: routine software/firmware support “for the foreseeable future,” but many newer features are incompatible.

Caveats

  • Discontinued hardware. Do not write a US add-to-cart.
  • Width, thickness, weight, and typical battery days are not on Previous Generations. The current FAQ battery table lists Ring 5, Ring 4, and Gen3 only.
  • Upgrading to a newer ring means signing up for membership (Oura).
  • Oura Ring is not a medical device (General FAQs / Product Safety).
  • Do not invent Gen1 zirconia specs on this titanium page. Gen1 is a different discontinued SKU without current firmware support.

Frequently asked questions

Does Gen2 need Oura Membership?

No. Oura: Gen2 users do not require membership and will not be charged membership fees. Newer features that need Gen3+ hardware will not appear. Upgrading to a newer ring requires signing up for membership.

Does Gen2 track daytime heart rate?

Not on the official hardware list. Gen2 IR LEDs are for nighttime heart rate and respiratory rate. Daytime / activity HR is a Gen3 addition.

Can I still buy Gen2 from Oura?

No. Oura says the Gen2 ring and charger are no longer available for purchase. The live store we opened listed Ring 5, Ring 4, and Ring 4 Ceramic only.

Is firmware still updating?

The firmware article last lists Gen2 4.0.8 on 18 October 2022. Membership support still says routine software/firmware updates “for the foreseeable future.” We do not invent a 2026 Gen2 build that is not on that list.
