The smart ring market is getting crowded, and Oura isn’t waiting around to see what happens next: it officially filed to go public on September 3. The Finnish company’s revenue nearly doubled to $1.21 billion for the nine months ended June 30.
The best smart rings are usually stuffed with health-monitoring features, such as the Oura Ring 5, while some models are specifically focused on a single dedicated task. These include blood pressure monitoring (like the Vital Signal Ring) or NFC payments, acting as a tiny digital wallet that lets you use your contactless credit cards.
Smart ring maker Circular on Thursday unveiled its upcoming Ring 3 series, which consists of a Pro model and a Slim option. Both of the smart rings will feature an integrated NFC chip for contactless payments, vibrating alerts for alarms and reminders, and more.
