Our verdict on each
ERA-FIT
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.
Oura
Oura suits anyone who wants sleep, temperature and recovery trends from a ring rather than a screen on the wrist, and who is comfortable with a monthly membership on top. It ranks 28 of 31 brands on starting price, at €265.30, with a membership of €5.99 a month.

Pros and cons
ERA-FIT
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.
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.
Oura
Pros
- Entry price of €265.30 is below Ultrahuman Amazon at €379, so the ring costs less at the point of purchase.
- The sensor set covers heart rate, spo2 and hrv, giving sleep, temperature, blood oxygen, heart rate and variability readings with nothing to wear on the wrist.
- A warranty of 1 to 2 years runs well past the 1 years of cover across the smart ring group.
Cons
- The membership adds €5.99 every month on top of a €265.30 ring, while the smart ring group sits at €0 a month, so a recurring charge is not the norm in this category.
- Battery life of 6 to 9 days is short next to the 14 days of the smart ring group, so charging becomes a regular habit.
- The range is smart ring only, while Amazfit covers smartwatch, fitness tracker and smart ring, so a watch, strap or scale has to come from another maker.
Who each suits
ERA-FIT
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.
Oura
Who it suits
- You want sleep, recovery and temperature trends without a display on your wrist, and you are happy to charge the ring every few days.
- You use an iPhone or an Android and want both supported, since the app covers iOS and Android.
- You prefer buying straight from the maker, with support on help centre, chat and email and a 1 to 2 year warranty behind the ring.
Who should look elsewhere
- Amazfit, if you want a ring alongside smartwatches, fitness trackers, chest straps and smart scales, since it covers smartwatch, fitness tracker and smart ring.
- Samsung, if you plan to combine a ring with a smartwatch from the same maker, since Samsung covers smartwatch and smart ring.
- Ultrahuman Amazon, if a higher starting price suits you: its ring begins at €379, close to the €379 top of the smart ring range.

Questions about each
ERA-FIT
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.
Oura
How much does the ring cost to buy?+
The ring starts at €265.30, below the €379 entry price at Ultrahuman Amazon. On starting price Oura ranks 28 of 31 brands, so it is one of the more expensive rings on the list even though it undercuts that rival.
Does the ring need a paid membership?+
Yes, the ring works alongside a membership that costs €5.99 a month, so the hardware is not the only ongoing charge. Oura ranks 13 of 21 brands on this monthly cost, which puts it past the middle of the field on recurring fees.
