Both skip the subscription, but they sit at opposite ends of the budget. The Amazfit Helio Ring is $199 and works across iOS and Android; the Samsung Galaxy Ring is roughly double at ~$399, with a better battery, build and tight integration — at its best on a Samsung Galaxy phone. This is cheapest-and-cross-platform vs pricier-and-more-polished.
VERDICT: TIE
Both are subscription-free. The Amazfit Helio Ring wins on price (~half) and true cross-platform support; the Samsung Galaxy Ring wins on battery, build, fit range and ecosystem integration for Samsung users. Pick by budget and whether you live in the Samsung ecosystem.
Amazfit Helio: $199. Samsung Galaxy Ring: ~$399. The Helio is roughly half the cost.
