RingConn Gen 2 Smart Ring - Sleep Apnea Monitoring & 12-Day Battery

Our review of the RingConn Gen 2 Smart Ring finds it best suited for people who want a discreet, multi-day wearable that prioritizes sleep health. The single biggest reason to consider it is the built-in sleep apnea monitoring backed by AI and clinical collaboration, which provides real-time AHI data without bulky equipment. Worn like a normal ring, it combines continuous tracking of sleep, heart rate, HRV and SpO2 with a comfortable, ultra-thin design and long battery life that keeps it running for up to 10-12 days on a charge.

Key Features

• Sleep apnea monitoring: Provides multi-night detection and real-time AHI readings using AI models developed with university and hospital partners for meaningful sleep insights.
• No subscription fees: Lifetime access to the RingConn Smart Health Monitoring App unlocks data and personalized insights without recurring charges.
• Long battery life: Delivers roughly 10-12 days of use on typical sizes and can extend with the smart charging case for far longer between full recharges.
• Durable waterproofing: Rated to 100m water resistance, making it suitable for daily wear, workouts and swimming without worry.
• Comprehensive health tracking: Monitors activity, sleep stages, stress, heart rate, HRV and blood oxygen saturation in a single, lightweight ring.
• OTA updates and compatibility: Receives over-the-air firmware improvements and works with Android and iOS through the companion app.

Who It's For

The RingConn Gen 2 is ideal for users who prioritize sleep health and want a minimally intrusive device to monitor sleep apnea signs and night-time breathing without a bulky home medical device. It also fits users who value long battery life, waterproofing to 100m and an always-on ring they can wear during workouts and sleep.

Those who should look elsewhere include buyers who cannot determine their correct ring size ahead of purchase or who prefer devices tied to subscription services for cloud analytics. Sizing is unique to RingConn, so the available sizing kit is recommended to avoid fit issues reported by some customers.
