Our verdict on each
Ambrosia Systems
Ambrosia Systems suits you if you want a single smart ring with a low entry price and a small monthly app fee. Hardware starts at $125, and the app membership is a separate recurring charge, so budget for both when you work out what a year of tracking costs you.
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
Ambrosia Systems
Pros
- Hardware starts at $125, and you can weigh that against the €265.30 Oura lists for its ring before you commit.
- The app membership is $9.97 a month, a lighter recurring charge than the €56.97 median monthly plan price across the site.
- Support runs on email, phone and help centre, so a hardware question can go to a person rather than a queue of messages.
Cons
- The warranty runs 1 year, the same figure as the 1 median in the smart ring ranking, so cover is not longer than the field.
- Water resistance of 1 m is not a swimming depth, so swimmers will need to take the ring off.
- The $9.97 app membership sits on top of the $125 hardware price, so the first year costs more than the entry figure.
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
Ambrosia Systems
Who it suits
- You are buying your first wearable and the $125 entry price matters more than brand name, which makes the gap against Oura's €265.30 the deciding point.
- You want one ring and one app, with readings available on iOS and Android so the phone you already own works.
- You are comfortable running a $9.97 monthly membership for the software behind the hardware.
Who should look elsewhere
- You want something to tap mid-session: this is a smart ring, so Amazfit's smartwatch, fitness tracker and smart ring or Samsung's smartwatch and smart ring suit you better.
- You want the longest hardware cover in the category, since the highest warranty in the smart ring ranking is 2 against 1 year here.
- You want a ring bundled with wrist devices from one maker, which Samsung's smartwatch and smart ring and Amazfit's smartwatch, fitness tracker and smart ring both cover.
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
Ambrosia Systems
What does the smart ring cost to buy?+
The ring starts at $125, which is the entry price for the hardware on its own. That figure does not include the app membership, billed separately at $9.97 a month. Readers weighing hardware cost should compare $125 with the €265.30 Oura lists for its ring.
Is there a monthly subscription on top of the ring?+
Yes, the app membership costs $9.97 a month. That is the recurring part of the bill, and it keeps running for as long as you keep the membership, unlike the $125 hardware price, which does not return each month. The median monthly plan price across the brands here is €56.97.
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.
