The Amazfit Helio Ring is the first smart ring from Chinese tech company Amazfit, best known for its budget-friendly fitness trackers, like the Amazfit Active 2 and its new open-ear earbuds, the Amazfit Up. Staying true to its brand, the Helio Ring undercuts the competition on price, offering a more affordable alternative to rivals like Oura with no added subscription fee.

The design is sleek and minimalist, with a titanium outer shell, and the ring is very comfortable to wear all day and night – possibly the most comfortable smart ring I’ve tested. The downside? It comes in just one finish and only three size options at the time of writing, which significantly limits your choice compared to competitors.

Functionally, the Helio Ring is built for sleep and wellness tracking. It offers in-depth sleep insights, heart rate monitoring, and energy tracking. There’s no auto-detection for workouts and there are only four workout modes to pick from. But, if one of those is your exercise of choice, you do get comprehensive data after each workout – and heart rate tracking as you exercise is accurate, too.
