What we left out, and why

  • Oura Ring 4: Oura now sells Ring 5, which it describes as 40% thinner, lighter and smaller, so we picked the current ring.
  • RingConn Gen 2 Air: RingConn's comparison table lists no vibration alerts, a 10-day battery and a heavier 2.5–4 g build than Gen 3.
  • Amazfit Helio Ring: Amazon UK lists only the Helio Ring sizing kit, not the ring itself, so we could not confirm it is on sale there.

How we chose

Our buying criteria

To make this list, a ring had to track sleep and heart rate, state its membership terms plainly and be sold in the UK in a range of sizes. Battery life runs from about 4 days to as much as 14 days per charge, and phone compatibility matters too, because the Galaxy Ring only pairs with Android. Water ratings are pressure ratings from the maker, so follow each maker's own advice on swimming. Each ring's facts come from its maker's own pages, read against its live Amazon UK listing, and each pick shows its catch.

  • Sizing: Sekonda comes in sizes 7 to 12 and the Galaxy Ring in 5 to 15; use a sizing kit before you buy.
  • Phone: the Galaxy Ring needs an Android 11+ phone; Oura and Ultrahuman work with iOS and Android.
  • Membership: Oura costs £5.99 a month or £69.99 a year after the first month; RingConn, Ultrahuman and Sekonda state no subscription.
  • Battery: match the days per charge to how you use your ring.
