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.
Wellue
Wellue suits anyone who wants a smart ring or smartwatch with no monthly fee attached. Buyers get a broad sensor set for a single $129 payment, and the 1 to 3 years warranty runs longer than many rivals offer. The short 3 days charge is the one thing to plan for.

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.
Wellue
Pros
- No recurring plan cost: the monthly membership is $0
- Sensor coverage spans heart rate, spo2 and sleep
- Works on both iOS and Android apps
Cons
- Battery life of 3 days means regular recharging, and it ranks 20 of 23 on that measure
- Entry price of $129 sits at 17 of 31 on price from, so it is not the cheapest here
- Support runs on email and help centre only, with no phone line listed

ERA-FIT
How much does the ERA-FIT ring cost, and is there a monthly fee?+
