RingConn Gen 2 Air
#4 in Smart Ring · Rated 4.5
AI-powered wellness ring with long battery life
RingConn Gen 2 Air is a slim, ultra-light smart ring designed for long battery life (up to 10 days) and AI-guided wellness insights. It emphasizes a low-power hardware stack, sleep tracking (including sleep stages), HR/HRV, SpO2, skin temperature, stress metrics, and daily activity, all accessible in an offline-friendly app. It supports iOS and Android, with RingConn Partner AI features available via the app. The Gen 2 line also includes a non-Air Gen 2 option with similar core sensing; both models have built a reputation for solid battery life and a no-subscription model, which helps them stand out against subscription-heavy rivals.
