RingConn Gen 2, Future Silver ($299)

Comfort is king when it comes to smart rings. You want it to be secure on the finger but not so tight that you have trouble removing it. Like many other ring manufacturers, RingConn offers a free sizing kit to test the size before you make your final purchase. This ensures you'll receive your perfect fit. The wearable is available in silver, black, and gold and has a seven-day battery life. The best thing about RingConn is the free access to all your metrics — heart rate, blood oxygen, sleep, stress, and activity tracking — sans a subscription. "This is extremely accurate," one reviewer wrote. "I have tested things like SPO, blood pressure, and sleep apnea with medical devices, and the ring works. It is convenient and looks like a standard ring."
