RingConn Gen 2 Air
RingConn's entry-level ring is a stripped-down Gen 2 at a lower price: RingConn lists it at $199, $100 below the Gen 2. It keeps the 2.0 mm by 6.8 mm profile and tracks sleep stages, heart rate, HRV, SpO2, skin temperature, respiratory rate, stress and menstrual cycles without a subscription. To hit the price it drops the Gen 2's sleep apnea monitoring, swaps titanium alloy for PVD-coated titanium steel (2.5-4 g, a little heavier) and replaces the portable charging case with a wired dock. Tom's Guide called it a great entry point into smart rings, while reviewers note it is weaker for workout tracking.

Our Verdict
The cheapest way into RingConn's tracking: it has the Gen 2's 2.0 mm by 6.8 mm profile and up to 10 days of rated battery, with iPhone and Android support, at a $199 list price, $100 under the Gen 2. It ranks fourth because it drops the Gen 2's sleep apnea monitoring, trades titanium alloy for slightly heavier PVD-coated titanium steel (2.5-4 g), and charges on a wired dock rather than a battery case. Against the Amazfit Helio Ring it wins clearly on battery (10 vs 4 days), size range (6-14 vs three sizes) and profile (2.0 vs 2.6 mm), which outweighs the Helio's lower price.

Alternatives to Consider
RingConn Gen 3
RingConn
RingConn's 2026 flagship and the most complete subscription-free ring sold on Amazon US. It keeps the Gen 2's sleep, heart rate, HRV, SpO2, skin temperature and sleep apnea pattern tracking, and adds the two things no other ring in this list has: a vibration motor for health reminders and nightly vascular (blood-pressure trend) insights. RingConn rates it at 10-12 days per charge with vibration on and up to 14 days with it off, the longest rating here, and its portable charging case holds months of top-ups. Trusted Reviews singled out its battery life as a highlight; Smart Ring HQ notes its sleep staging still trails the subscription-based Oura Ring.
RingConn Gen 2
RingConn
The predecessor to the Gen 3 and still the value pick for subscription-free sleep tracking. RingConn's Gen 2 introduced the brand's sleep apnea monitoring (an OSA risk assessment built on SpO2 readings taken about every two seconds overnight) and shares the Gen 3's core heart rate, HRV, skin temperature and sleep-stage tracking. At 2.0 mm thick and 2-3 g, it is the slimmest and lightest ring here, and its 10-12 day rating plus a 150-day charging case put it close to the Gen 3 on battery. RingConn lists it at $299, and Amazon has regularly sold it for less since the Gen 3 launched. TechRadar and Android Central both rated it a strong cheaper alternative to Oura.
Samsung Galaxy Ring
Samsung
Samsung's titanium ring is the most polished subscription-free option for Android owners, and the most tightly integrated for Galaxy phone owners. All of Samsung Health's ring features, including the daily Energy Score, sleep analysis, skin temperature and cycle tracking, are included without a fee, and Galaxy phones add a double-pinch gesture to take photos or dismiss alarms plus Find My Ring. The trade-offs are compatibility and battery: it requires Android 11 or newer and does not work with iPhone, and Samsung rates it at up to 7 days per charge, about half the RingConn Gen 3's rating. Samsung lists it at $399.99, the highest list price here, though Amazon and Samsung have discounted it repeatedly through 2026.
Amazfit Helio Ring
Amazfit
The cheapest ring here and the only one with an EDA (electrodermal activity) sensor for stress tracking. It launched at $299, Amazfit cut it permanently to $199, and Amazon has since sold it for less. Amazfit also made its Zepp Aura and readiness features free for life, so every feature is included. Live Science and Tom's Guide both rated its sleep tracking well for the money. The compromises are significant, though: Amazfit rates it at up to 4 days per charge (Live Science saw about 3), it comes in only three sizes (8, 10 and 12), and at 2.6 mm thick and 8 mm wide it is the bulkiest ring in this list.
