Amazfit Helio Ring vs RingConn Gen 2 (2026)

These are the two rings people cross-shop when they want smart-ring tracking without a subscription and without Oura money. The Amazfit Helio Ring is the cheapest at $199; the RingConn Gen 2 costs a little more ($249) but answers the Helio’s two biggest weaknesses — battery and fit — with a ~12-day charge and a wider size range.

VERDICT: TIE

Both are budget, subscription-free rings. The Amazfit Helio Ring is cheaper up front ($199) and lighter; the RingConn Gen 2 wins where it matters day-to-day — a ~12-day battery (vs ~2.5–3), more sizes, and solid tracking for $249. For most people RingConn is the better buy; the Helio wins on lowest price and comfort if a size fits.
