The Amazfit Helio Ring is a sleek and lightweight smart ring that stands out for design and comfort. It offers sleep and wellness tracking, a straightforward app and a more affordable price than higher-end rivals – without any subscription fees. It’s not as refined as the latest Oura Ring and limited size options, along with only a few workout modes and only a 3-day battery, hold it back. But if sleep is your priority and you’re looking for a more affordable way to track it from your finger rather than your wrist, the Amazfit Helio Ring is a strong contender.
