- Cheaper entry to Oura
- 7-day battery
Tradeoffs
- Discontinued — Oura no longer sells it directly
- Subscription mandatory after first month

Common questions
- How much does the Oura Ring Generation 3 cost?

- Does the Oura Ring Generation 3 require a subscription?
- Yes. The Oura Ring Generation 3 needs an active Oura membership at $5.99/month — without it the device stops reporting your data.
- How long does the Oura Ring Generation 3 battery last?
- About 7 days of typical use per charge. Heavy GPS use, an always-on display, and continuous sensing all pull that number down.
- Is the Oura Ring Generation 3 waterproof?

- It pairs with both iPhone and Android.
- Is the Oura Ring Generation 3 still worth buying?
- The Oura Ring Generation 3 came out in 2021 and Oura has discontinued it, so new stock is limited and prices vary. Check it against the current ring lineup before buying.
