Samsung Galaxy Ring vs Amazfit Helio Ring

How they differ in real use

Built from our smart rings without subscription scoring, each product's published specifications, and verified owner feedback — not hands-on testing.

Both the Samsung Galaxy Ring and the Amazfit Helio Ring made our Top 5 Smart Rings Without a Subscription, at #3 (best premium) and #5 (best budget). The most polished free app here: Samsung Health's Energy Score, sleep and cycle tracking are all included, and Galaxy phone owners get a double-pinch gesture for the camera and alarms plus Find My Ring, which no RingConn offers. It has the widest size range (5-15) and a 10ATM rating. It ranks third because it is Android-only, its 7-day rating is well short of the RingConns' 10-14 days, it has no sleep apnea screening on the ring, and it carries the highest list price at $399.99. It outranks the Gen 2 Air on tracking polish and build, despite the Air's longer 10-day battery and lower price. The lowest-cost ring here, and the only one with an EDA sensor for a direct stress signal; Amazfit has made every Zepp feature free for life, and Live Science and Tom's Guide both rated its sleep tracking well for the price. It ranks last because its up-to-4-day rating (about 3 days in Live Science's use) is less than half the Gen 2 Air's 10 days, it comes in only sizes 8, 10 and 12, and at 2.6 mm by 8 mm it is the bulkiest ring in the list. Buy it only if price matters more than charging frequency and your size is offered.

We score smart rings without a subscription on Tracking Accuracy (25%), Battery Life (20%), Health Features (15%), App & Insights (15%), Comfort & Build (10%) and Value (15%). On that basis the Samsung Galaxy Ring totals 7.5 out of 10 and the Amazfit Helio Ring 6.6. The widest gap is App & Insights, where the Samsung Galaxy Ring scores 9 against 6 for the Amazfit Helio Ring: how clearly the free app turns raw data into readiness, sleep and recovery guidance, and how well it syncs with Apple Health or Health Connect. Battery Life also separates them: 6 for the Samsung Galaxy Ring versus 4 for the Amazfit Helio Ring. The Amazfit Helio Ring claws back ground on Value.
