Oura Ring 4: What Membership Actually Unlocks

Oura is honest about the split: the hardware and the Membership work together. On the Membership page (checked October 15, 2026), US pricing is $5.99 per month or $69.99 per year before tax, and new members get the first month included. Oura's support article and product FAQ state that without Membership you only get limited functionality — not the full suite of detailed insights.

With active Membership, Oura Ring 4 marketing and support pages list detailed sleep analysis, 24/7 heart-rate related tracking, SpO2 sensing, daytime stress, women's health features (including Cycle Insights and Pregnancy Insights), heart-health metrics and more. Treat feature lists as manufacturer claims; we have not independently verified every metric's accuracy.

Hardware snapshot from Oura's Ring 4 store pages (October 15, 2026): titanium build, about 7.90 mm width / 2.88 mm thickness, 3.3–5.2 g, 5–8 days battery (depends on size and settings), water resistance up to 100 m. Ceramic Ring 4 is thicker (3.51 mm) and heavier (5.1–8.1 g) with a zirconia exterior; Petal is a Ceramic finish, not a cover.

RingConn Gen 2: No-Subscription Flagship Alternative

RingConn's Gen 2 product page (checked October 15, 2026) lists $299, no subscription required, 10–12 days battery (size-dependent; up to 150 days with the included charging case claim), about 2–3 g / 2 mm thick, titanium alloy with medical-grade epoxy, and IP68 / 100 m water resistance. The brand highlights sleep-apnea monitoring accuracy figures on its marketing page; treat clinical-sounding claims as marketing until you read the underlying study methods.

RingConn also sells Gen 2 Air at a lower official comparison price ($199 in RingConn's own Gen 2 comparison table). Use a sizing kit: RingConn states its sizes differ from standard jewelry sizes and from other smart rings. For dated RingConn campaign notes on this site, see our RingConn brand page.

Samsung Galaxy Ring: No Fee, Android Ecosystem Tax

Samsung's U.S. Galaxy Ring hub (samsung.com/us/rings/galaxy-ring/, checked October 15, 2026) positions the ring as an all-day titanium wearable with sleep, heart-rate and skin-temperature sensors feeding Samsung Health, plus Galaxy AI features such as Energy Score. Official copy emphasizes up to 7 days of battery (smaller sizes may be less) and water resistance consistent with a 10ATM / IP68 class footnote.

Amazon U.S. listings are titled No App Subscription. That matches the absence of a separate paid ring membership on the Samsung pages we checked. The real constraint is software: Android smartphones only, with a Samsung account, and some controls (Double Pinch, Find My Ring) requiring a compatible Galaxy phone. iPhone users should not buy Galaxy Ring expecting full feature parity.

For Samsung promo codes and Offer Program context (tablets and other categories — not a Galaxy Ring coupon claim), see our Samsung brand page.

Amazfit Helio Ring — Not “Halo Ring 3”

Shoppers searching “Halo Ring 3” often land on a different brand (Halo Ring storefronts) or misspell Amazfit's Helio Ring. As of October 15, 2026, Amazfit's documented product name is Amazfit Helio Ring (Amazon model number W2321TY1N on the Size 10 listing). We could not load Amazfit's U.S. product URL (404 from our fetch); specs below rely on the Amazon US listing checked the same day.

Amazon's Helio listing markets Subscription Free health features in the Zepp App, titanium alloy build, sleep/stress/heart tracking, and limited size SKUs (commonly 8 / 10 / 12 plus a sizing kit). Displayed price for Size 10 was about $157.72 on October 15, 2026. Battery marketing often cites roughly 4 days; customer reviews on that listing frequently dispute battery longevity — confirm current listing claims and reviews before buying.

What Matters Specifically for Women Shoppers

• Cycle and temperature features appear on Oura (Membership), RingConn, Galaxy Ring and Helio marketing. None of these are contraception; Samsung's own cycle footnote says results can be affected by hormones, illness and wear time.
• Finger size and swelling: all four brands warn that smart-ring sizes differ from jewelry sizes. Order a sizing kit and wear it overnight before locking a size.
• Subscription math for Oura: at $69.99/year, three years of Membership is about $210 before tax — often more than the gap between Oura hardware and a no-subscription ring. If you will cancel Membership, budget for limited app functionality.
• Phone OS: Galaxy Ring rules out iPhone. Oura, RingConn and Helio all advertise iOS and Android support on the pages we checked.
• Covers and finishes: searching “Oura Ring 4 petal” usually means the Ceramic Petal finish, or third-party covers that borrowed the color name. See our smart ring covers and accessories guide.

Which Should You Buy?

• Strict no recurring fee + iPhone or Android: RingConn Gen 2 if you want the brand's apnea-monitoring pitch and longer stated battery; Helio Ring if budget is the priority and you accept Amazfit/Zepp ecosystem trade-offs.
• Already in Samsung Galaxy + Android: Galaxy Ring for Samsung Health integration — accept Android-only limits.
• Want Oura's insight depth and accept Membership: Oura Ring 4 titanium from $349 + $5.99/mo (or $69.99/yr) after the included month; Ceramic Petal if you specifically want that finish at $399.
• Searching Halo Ring 3: verify you mean Amazfit Helio Ring or a separate Halo-branded product; do not assume they are the same device.
