Frequently Asked Questions
Which smart rings don't have a monthly subscription fee?
Both the Samsung Galaxy Ring and the RingConn Gen 2 are 100% subscription-free. Once you buy the hardware, you get lifetime access to all your health, sleep, and recovery data. The Oura Ring 4, however, requires a $5.99/month membership.
Can the RingConn Gen 2 detect sleep apnea?
Yes. The RingConn Gen 2 features built-in, AI-powered sleep apnea monitoring. It tracks overnight drops in blood oxygen (SpO2) and breathing disturbances, boasting an impressive 90.7% accuracy rate for identifying apnea-related episodes.
How long does the RingConn Gen 2 battery actually last?
The RingConn Gen 2 ring itself lasts between 10 to 12 days on a single charge (the longest on the market). However, it comes with a portable charging case that holds enough reserve power to keep the ring charged for up to 150 days of total travel time.
Does the Samsung Galaxy Ring work with an iPhone?
No. The Samsung Galaxy Ring is exclusively compatible with Android smartphones (specifically optimized for Samsung Galaxy devices). If you use an iPhone, you must choose either the Oura Ring 4 or the RingConn Gen 2.
Do smart rings scratch easily when lifting weights at the gym?
Yes. While Oura, Samsung, and RingConn rings are made of durable titanium, metal-on-metal friction from knurled barbells and dumbbells will scratch the finish. It is highly recommended to wear a silicone ring protector or remove the smart ring during heavy weightlifting.
Is the Oura Ring 4 worth buying despite the $5.99/month subscription?
Yes, if your primary goal is clinical-grade sleep staging, HRV accuracy, and detailed cycle tracking. The Oura Ring 4 features recessed sensors for extreme comfort. However, if you refuse to pay recurring fees, choose the RingConn Gen 2 instead.
