Ray or RingConn Gen 2?
A 2–3 gram ring with sleep-apnea monitoring, compared with a light-powered band.
RingConn Gen 2 is a very light smart ring, at 2–3 grams, with no subscription and automatic sleep-apnea monitoring. It's $299 at list and lasts 10 to 12 days per charge, plus extra charges from its case. Ray is a 7-gram wristband with no subscription that powers itself from light.
The short answer
Choose RingConn Gen 2 if you want a ring with sleep-apnea monitoring and long battery life at no monthly cost. Choose Ray if you'd rather wear a band and drop the charging case entirely.
