The Anarow Smart Ring is a minimalist health tracker that moves the sensors from your wrist to your finger. It runs on Wear OS 3.0 and offers a surprisingly detailed look at your daily wellness without the bulk of a watch.

You get continuous heart rate and SpO2 monitoring, plus sleep tracking that breaks down your light, deep, and REM cycles. The 4MB of onboard storage handles a day’s data before syncing. In practice, the ring is lightweight and unobtrusive for 24/7 wear. The sensors require a proper fit to work consistently, so using the provided size guide is essential—if you’re between sizes, go larger.

Battery life comes from a single lithium polymer cell, typically lasting several days on a charge. The companion SmartHealth app presents your daily and weekly insights clearly. Just know its accuracy for medical-grade metrics like blood pressure is limited; view it as a helpful wellness trendspotter, not a diagnostic device.
