Our verdict
ERA-FIT suits anyone who wants a screenless smart ring with no subscription attached, since the Nextring runs at €0 a month and membership is not required. The trade-off is coverage: it ships to AT, DE and CH and carries 1 year of warranty, so buy it for tracking rather than for a broad hardware lineup.

Pros and cons
Pros
- No membership required, and the monthly plan price is €0, so the €219 ring is the whole outlay.
- Battery life of 10 to 14 days and water resistance to 100 metres suit overnight and pool wear.
- The sensor set covers heart rate, spo2 and skin temperature in one ring.
- A 30 day money back window takes the sizing risk out of the €219 entry price.
- Entry price of €219 sits below Oura at €265.30.
Cons
- Warranty cover of 1 year is thin for a device you sleep and swim in.
- Support runs on email and chat only, so sizing and setup questions go by email or chat rather than a call.
- A screen of 0 inches means nothing shows on your wrist, so the phone has to be within hand for every reading.
- Shipping covers AT, DE and CH, so buyers outside those markets need a forwarder.
Who it suits
- Buyers who want recovery and sleep data without a monthly fee, since membership is listed as not required and the plan price is €0.
- People who would rather not wear a display, given a screen of 0 inches and readings held in the app.
- Customers in Austria, DE and CH who wear the ring in water to 100 metres.
Who should look elsewhere
- Anyone who wants a watch, fitness tracker, chest strap or smart scale from the same maker, since smartwatch, fitness tracker and smart ring covers those types.
- Buyers settled on Oura and ready to pay more, since that ring starts at €265.30 against ERA-FIT at €219.
- Shoppers who want a smartwatch and a ring from one brand, since smartwatch and smart ring lists both.
What it does well
The Nextring is a screenless smart ring built for continuous wear rather than glanceable readouts. Battery life is listed as 10 to 14 days, which puts charging on a loose rhythm rather than a nightly one, and water resistance of 100 metres covers showering and pool sessions. The trade sits in the paperwork rather than the hardware: warranty cover runs 1 year, a short term for a device that stays on the hand and in the water overnight.
Where it sits among rivals
On hardware price, ERA-FIT sits at position 26 of 31 brands, so the ring lands in the middle of the field rather than at either edge. On the monthly plan price the ranking inverts: position 1 of 21 brands. Read together, the buying case is the running cost rather than the ticket price, since the hardware ranks mid-table while the recurring figure ranks at the top of its list.
Who runs it
The ring comes from ERA-FIT GmbH, registered in Austria, so the brand is a single-country operation selling into neighbouring markets. Support runs on email and chat, with email and chat listed as the contact routes, which suits buyers who are comfortable handling sizing and setup questions digitally. Anyone who wants a phone line to talk a ring size through should look at brands that publish more contact options.

Frequently asked questions
How much does the ERA-FIT ring cost, and is there a monthly fee?+
The Nextring is listed from €219, paid once for the hardware. Membership is listed as not required and the monthly plan price is €0, so the checkout figure stays the recurring figure unless other hardware is added later.
Do I need a membership to use the ring?+
Membership is listed as not required and the monthly plan price is €0. The readings come through the phone apps on iOS and Android, and the ring carries heart rate, spo2 and skin temperature for tracking. Any paid tier would sit outside the ring, so the ring itself adds no renewal charge.
How long does the battery last between charges?+
Battery life is listed as 10 to 14 days, a range rather than a fixed number. For a ring worn overnight for sleep data, that cadence puts charging on a loose schedule instead of a nightly one. Battery endurance is the main argument for a ring over a wrist-worn display.
Can I swim and shower with the ring?+
Water resistance is listed to 100 metres, so showers and pool sessions sit within the stated rating. With a screen of 0 inches there is no display to worry about, and the sensors listed as heart rate, spo2 and skin temperature carry the swim and sleep readings.
Which phones and apps does the ring work with?+
The ring pairs with phones on iOS and Android, so the app side covers the usual mobile platforms. Because the screen is 0 inches, heart rate, sleep, skin temperature and HRV trends are read in the phone app rather than looked at on the wrist.
Which countries can I order the ring in?+
ERA-FIT lists AT, DE and CH as the markets it ships to. Buyers in those markets can order the Nextring direct; outside them the ring is outside the stated coverage, so delivery would need a forwarder or a different brand.
What cover do I get after buying, if it fails or does not fit?+
Buyers have a 30 day money back window from ERA-FIT GmbH, and the ring carries 1 year warranty cover. Fit is the usual reason to spend that window, because a ring that sits wrong is hard to live with.
Who does the ERA-FIT ring suit?+
It fits people who want sleep, heart rate, skin temperature and HRV data without a monthly plan price of €0 attached, and who would rather carry no display. The only product type listed is smart ring, so it is a single device rather than an ecosystem.
