The RingConn Gen 2 Air is built for people who want wearable health tracking without a bulky watch. This ultra-thin smart ring combines multi-sensor tracking with an AI assistant that turns your daily data into easy-to-digest reports and guidance for building better habits.

Designed for all-day comfort, it features a super-thin 2mm profile and a lightweight 2.5g build—so it stays out of the way during workouts, at work, and overnight. It’s also rated IP68 waterproof (tested to 100m/328ft), making it a practical pick for daily wear including showers, swimming, and diving.

Battery life is a standout: get up to 10 days on a full charge, with a recharge time of about 90 minutes. You’ll also appreciate that standard features in the RingConn app don’t require a subscription, helping keep long-term ownership costs predictable. Note: RingConn uses its own sizing standards, so it’s recommended to use the RingConn Sizing Kit before buying for the best fit.
