elegant design and small size and weight
relatively durable
battery life about 6 days
no subscription fee (unlike Oura)
no extra charge for different colours (unlike Oura)
accurate measurement of lots of data
further updates and continuous improvement of functions and data processing and measurement almost every week
from summer 2025 the problem with PCB boards and battery failures should be solved - time will tell, so far everything is without problem
technical support response and customer care UH
the app in English is sometimes translated strangely and often does not use diacritics

After 2 weeks, for several consecutive days in the morning it did not sync, needed to recharge, hence the sleep index was not recorded.
I've been waiting over 14 days for a claim, so I bought a ring for 9,5k and so far I've been waiting longer for a claim than what it served me.

I like the way he tracks sleep
Calculation of steps and burning off

After two weeks, unfortunately, the synchronization with the app started to fail.

Complained several times with the manufacturer, changed 3 times so far, each time something doesn't work.
When sending a new ring from India, it is always necessary to communicate in customs.
broken product
every broken ring is thrown away

Oura or Ultrahuman? That was the question. There was one decision: There is no subscription fee with Ultrahuman, only payment for your own smartring. Size selection easy thanks to the test size kit and the titanium colour most interesting to me.
I definitely don't regret the decision, even though after the first three days and three battery charges I panic about battery life. Repeatedly, after approx. 30 hours the battery drained 30 percent! Plus disappointment that no one responded after emailing Ultrahuman directly. I was already determined to claim on Alza.cz, but fortunately the battery problem can be dealt with, as I accidentally found: directly in the app there is a small note that a "soft reset" is recommended in case of battery problems. And voilà. After it is done, the battery life is 5 days fine (and still about 10% reserve).
So now complete satisfaction. Smartring is doing exactly what it is supposed to do and the way it is supposed to do it: -)
Design (appearance, colour, execution)
Weight and dimensions (with respect to size)
Range of measured values
Mobile apps (for iOS)
No subscription fee (unlike Oura)
After the first few days panic about endurance (almost 80% drained in 30 hours), but successfully solved by resetting

Total waste, they changed my ring 5 times because of a faulty battery in one year. I've given up, I'm tired of constantly having to deal with mailings for another junk ring. They tried to shut me up with some bullshit series. Support isn't even responding anymore.

Unfortunately, I think I may have had a defective piece: (
- battery life max 36 hours and then 2-3 hours charging
- Steps over short distances didn't count for me (in the kitchen, on the toilet, etc).
- Sleep was recorded even when I was awake for an hour playing with my cell phone.

It works fine before it breaks down.
Second ring since December 2024, always lasts about 1.5 months and then can't connect to phone.
