Our verdict on each
Circular
Circular suits anyone who wants a smart ring without a recurring subscription, and it holds the top spot on membership cost with a monthly fee of $0. The catch is endurance: 8 days of battery sits below what rivals manage.
RingConn
RingConn suits people who want a smart ring and refuse to pay a monthly membership to read their own data. It starts at $199 and the membership costs $0, so the outlay stops at the ring. The trade-off is a CN company, founded in 2021, rather than a household name.

Pros and cons
Circular
Pros
- No recurring membership charge at $0, which ranks 1 of 21 brands.
- Entry price of $349 is a single hardware cost rather than a package that hides a subscription.
- Water resistance of 50 metres suits swimming, showering and general wear.
Cons
- Battery life of 8 days ranks 16 of 23 brands, so charging is more frequent.
- The entry price of $349 sits at 29 of 31 brands, so the hardware itself is not the cheapest.
- Support runs on email, chat and help centre only, with no phone line listed.
RingConn
Pros
- Membership of $0 means the app and the scores cost nothing extra after the ring is bought.
- Battery of 14 days holds up against the smart ring field median of 14.
- Sensors cover heart rate, spo2 and hrv, with skin temperature and heart rate variability both well represented in the field.
Cons
- Battery of 14 days ranks below the smart ring field leader, where the median listed ring runs to 21.
- The company sits in CN under Shenzhen Ninenovo Technology Limited, so buyers who prefer a domestic support base are buying cross border.
- Warranty runs 1 to 2 years, at the low end where the smart ring list reaches 2.
Who each suits
Circular
Who it suits
- Buyers who want a ring and no monthly membership, given the fee of $0.
- People who care about durability over battery, with resistance of 50 metres and a 1 year warranty.
- Senders who travel often, since Circular Health Limited ships across LV, JP and IN.
Who should look elsewhere
- Battery-first buyers, who should look at Oura, where the entry price starts at €265.30.
- Shoppers who want a ring plus a watch, since Amazfit and Samsung both list wider product ranges while Circular sells smart ring only.
RingConn
Who it suits
- Readers who want a smart ring and would rather not pay a monthly membership, since the membership costs $0.
- Swimmers and shift workers who need a ring that keeps working between charges, with 14 days of battery and 100 m water resistance.
- Buyers outside a single home market, since the shipping list covers US, CA and MX.
Who should look elsewhere
- Oura buyers who want a brand with a longer established retail presence, and are happy to consider €265.30 hardware.
- Amazfit buyers who want one account covering more than a ring, since Amazfit also lists smartwatch, fitness tracker and smart ring.
- Samsung buyers who already want the ring to sit alongside a watch, given Samsung lists smartwatch and smart ring.

Questions about each
Circular
How much does the Circular ring cost?+
The entry price is $349, charged for the hardware itself. There is no joining fee to use it, since the membership costs $0. Readers comparing total ownership over several years will find the hardware cost is front loaded rather than spread across a subscription.
Is there a membership fee for Circular?+
No monthly membership is charged, as the membership costs $0. That places Circular 1 of 21 brands on that measure. It is the main reason to pick this ring over rivals that tie the app to a recurring plan.
RingConn
How much does a RingConn ring cost?+
RingConn smart rings start at $199 for the hardware itself. There is no bundle to unpack and no tiered plan to read through, since the range is a single product type. Buyers pay once at checkout and the ring arrives ready to pair.
Does RingConn charge a monthly membership?+
No. The monthly membership is $0, so the ongoing cost sits at zero. Sleep, recovery and readiness scores from the app work without a paid tier, which is the main reason this ring separates itself from subscription rivals.
