The fast calculator
Use this as the pre-checkout math before you decide which ring deserves the click. Prices move, taxes vary, and promotions change, so treat this as a decision model, not a live cart. The point is to separate cheap checkout from low ownership cost.
| Smart ring | Simple one-year math | Simple three-year math |
|---|---|---|
| Oura Ring 4 | $349 hardware + about $64 after included first month on annual membership | About $559 before tax with annual membership |
| Samsung Galaxy Ring | $399.99 hardware, no separate ring membership | $399.99 before tax if you stay in Samsung Health |
| RingConn Gen 2 Air | $199 hardware, no subscription-fee positioning | $199 before tax if the app stays free for your use case |
| Circular Ring 2 | $349+ hardware, core features positioned subscription-free | $349+ before tax, with premium-feature caveats |
| Amazfit Helio Ring | $149.99 hardware, Zepp ecosystem caveats | $149.99 before tax if you do not need paid Zepp Aura features |
Product paths
Oura Ring 4
Oura Ring 4 is the premium smart ring to buy if you will use the sleep, readiness, stress, activity, and behavior-change app enough to justify hardware plus membership.
Strengths
- Best smart-ring app maturity
- Works across iPhone and Android
- Strongest sleep and readiness behavior loop
Tradeoffs
- Membership changes long-term cost
- Most expensive if you ignore app value
- Not a smartwatch replacement
Samsung Galaxy Ring
Samsung Galaxy Ring is the cleanest premium no-separate-membership smart ring if you use a compatible Galaxy phone and want Samsung Health as the home base.
Strengths
- No separate ring membership
- Strong Samsung Health fit
- Premium retail and support path
Tradeoffs
- Weak recommendation outside Galaxy
- Higher checkout price than RingConn or Amazfit
- Not for iPhone buyers
RingConn Gen 2 Air
RingConn Gen 2 Air is the value pick if you want a $199 smart ring with no subscription-fee positioning and a lower ownership-cost ceiling.
Strengths
- Lowest clean long-term cost in this set
- No subscription-fee positioning
- Up to 10 days of battery life
Tradeoffs
- Less proven app than Oura
- Direct-first purchase path
- Value buy, not safest premium buy
Circular Ring 2
Circular Ring 2 is the premium subscription-free-core bet for buyers who specifically want ECG, AFib positioning, HSA/FSA eligibility, and a more health-signal-forward smart ring.
Strengths
- No-subscription core positioning
- ECG and AFib angle
- Premium health-signal differentiation
Tradeoffs
- Some premium-feature caveats
- Smaller-brand support risk
- Not the lowest-cost no-subscription ring
Amazfit Helio Ring
Amazfit Helio Ring is the low-checkout-cost Zepp ecosystem ring, but its shorter battery life, narrow sizing, and readiness-subscription language keep it from being the cleanest no-fee recommendation.
Strengths
- Lowest official price in this set
- Best fit for Zepp and Amazfit users
- Cheap way to test the ring habit
Tradeoffs
- Readiness and Zepp Aura language needs caution
- Only sizes 8, 10, and 12 on the US page
- Up to 4 days of battery life
The ownership-cost rule
Do not compare smart rings only on sticker price. Compare the cost of the ring, the cost of the app, the phone ecosystem required to make the app useful, and the odds that you will still wear the ring after the first month.
That is why the cheapest ring is not always the winner. A $149.99 ring that does not fit your app life is worse than a $349 ring you wear every night. But a $349 ring with a paid app is also a bad buy if you only wanted sleep duration and a morning score.
Oura membership math
Oura is the easiest ring to recommend and the hardest ring to defend on pure cost. The hardware starts at a premium price, and the full app experience depends on Oura Membership after the included first month for new members. Oura lists US membership at $5.99 per month or $69.99 per year before tax.
Simple annual math makes the decision clearer:
- Year one with annual membership after the included first month: about $413 before tax.
- Three years with annual membership: about $559 before tax.
- Monthly membership is easier to start but usually worse if you keep the ring.

Samsung vs Oura cost math
Samsung Galaxy Ring can be the better three-year deal for Galaxy buyers even though the checkout price is higher. The catch is ecosystem dependency. If a compatible Galaxy phone, Samsung account, and Samsung Health are already part of your life, Samsung’s no-separate-ring-membership story is powerful.
If you use iPhone or might leave Galaxy soon, that same advantage becomes fragile. You are not just buying a ring. You are buying the Samsung Health workflow around the ring.

RingConn vs Oura cost math
RingConn Gen 2 Air is the sharpest cost-control answer. The official direct price is $199, and RingConn’s comparison table positions the subscription fee as free. That gives it a much lower three-year cost ceiling than Oura.
The tradeoff is app confidence. If you want the strongest smart-ring software, Oura still has the safer premium case. If you want a lower-cost sleep and wellness ring without recurring app math, RingConn is the ring to pressure test first.

Circular and Amazfit cost caveats
Circular Ring 2 and Amazfit Helio Ring are the two places where “no subscription” needs a careful read. Circular markets core features without a subscription, but premium-feature and coin language still matters if you are buying for future features. Amazfit has the lowest checkout price, but the Zepp Aura and readiness language makes it less clean than RingConn for subscription-sensitive buyers.
Buy Circular if ECG and AFib positioning are specifically why you are shopping. Buy Amazfit if you already use Zepp or Amazfit watches and the low checkout price is the point.

When the subscription is worth it
Pay for Oura Membership if the app changes behavior. That means you actually adjust bedtime, recovery, workouts, alcohol, caffeine, stress, or illness response because of what the app tells you. In that case, the subscription can be the product.
Do not pay for membership if all you want is a passive tracker that confirms you slept badly. For that buyer, Samsung, RingConn, Garmin, Withings, or a cheap band can be the better business decision.

Bottom line

How much does Oura Ring 4 cost after three years?
Using the $349 entry hardware price and $69.99 annual Oura Membership after the included first month, a simple three-year Oura Ring 4 estimate is about $559 before tax if you keep annual membership active.
Is Samsung Galaxy Ring cheaper than Oura over time?

Should I ignore subscriptions and just buy the best ring?
Ignore subscription cost only if the app changes your behavior. If you will not open the app and act on the coaching, buy a no-subscription smart ring or a watch instead.
