The Ringconn Gen 2 offers a no-subscription model, 10 to 12 days battery life, and accurate sleep metrics, making it a favorable alternative to smartwatches.

Fitness bands and smart rings, like the Ringconn, provide crucial health metrics while being more convenient than smart watches, appealing to those who prefer minimal wear.
