Smart rings are shockingly good at step counting, with one critical flaw
Our favorite smart rings are near-perfect at step counts when you're walking. When you're sitting still, they're much iffier.
They can't sample your heart rate as often because of smaller battery capacity, they become less accurate when your fingers swell from faster blood flow, and you have no screen to check your progress. In my cheap fitness watch accuracy test this March, the Forerunner 165 (+11 steps after 5,000) did excellently, while the Coros Pace 3 (+84) and Fitbit Charge 6 (-199) weren't quite as reliable.
