UniJethro’s smart ring puts your health metrics on your finger, literally. The integrated display is the key difference, letting you check heart rate or blood oxygen with a glance instead of pulling out your phone. It’s a subtle but practical shift for staying aware without being intrusive.

In daily use, the ring tracks the essentials: continuous heart rate, sleep stages, and stress via HRV. The gesture controls for flipping pages or scrolling videos on an iPhone feel surprisingly intuitive once mapped. You get about a week of battery, which is solid for a device with a screen. The 64MB of storage handles your historical data without issue.

It’s worth noting the display is small, so notifications show a caller’s name or number, not full messages. The fit is crucial for sensor accuracy, so use the sizing kit. For a streamlined way to keep tabs on your vitals without adding another screen to stare at, this ring makes a compelling case.
