Our verdict on each
METZ
METZ suits European buyers who want a smart ring and a smartwatch from one young brand, with the METZ entry product at €99.90 and a 2 years warranty behind it. The trade-off is battery: the ring runs 10 days, below the smart ring field median, so value buyers gain more here than endurance buyers.
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
METZ
Pros
- The range covers smart ring and smartwatch, so a ring and a watch come from one seller rather than two.
- The ring's heart rate, spo2 and skin temperature cover heart rate, blood oxygen, skin temperature and sleep, and the apps run on iOS and Android.
- Support runs on email, phone and help centre, so email, phone and a help centre are all available routes.
Cons
- Battery life of 10 days falls short of the smart ring median 14 and of the smartwatch median 11.5.
- The catalogue stops at smart ring and smartwatch, while Amazfit lists smartwatch, fitness tracker and smart ring, so a chest strap and a smart scale sit outside the METZ range.
- Shipping reaches AT, BE and BG, and that list does not extend past those markets.
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
METZ
Who it suits
- Value buyers inside METZ's shipping markets, who get a ring and a watch starting at €99.90 with a 2 years warranty behind them.
- People who want phone and help centre support rather than email alone, since support runs on email, phone and help centre.
- Swimmers and showerers, since the ring is water resistant to 100 m and reads heart rate, blood oxygen, skin temperature and sleep.
Who should look elsewhere
- Readers who want fitness trackers as well as watches, since Runmefit lists smartwatch and fitness tracker and the METZ range is smart ring and smartwatch.
- Shoppers who want a chest strap or a smart scale, since Amazfit lists smartwatch, fitness tracker and smart ring and those types are not in the METZ range.
- Watch-only buyers, since Oukitel's smartwatch is a watch line and METZ splits smart ring and smartwatch between a ring and a watch.
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
METZ
What does METZ cost to get started?+
The METZ entry product is €99.90, a hardware price set against the smartwatches and fitness trackers median of €99.90 and the smart rings median of €174.52. Buyers working to a budget get entry level gear here for less than the typical price in either category.
How long does the METZ ring last on a charge?+
The listed ring runs 10 days, under the smart ring median of 14 and under the smartwatch median of 11.5. METZ ranks 13 of 23 brands on battery days, so plan on regular charging rather than a set and forget device.
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.
