No need to provide a link. Rings that use the SmartHealth app are inferior to "Colmi" rings which use the QRing app. The SmartHealth app is among the worst on the market. There are a few below it, app-wise, but best avoided. SmartHealth has some weird permissions and behavior on Android for me as we

If you pay €50 for a Colmi branded ring, you are paying ~€30-40 too much...less shipping costs anyway. All models are available on Temu and Ali and are identical to those with the Colmi name on them. Just search for the model number and visually match the photo.

For me product itself looks too good to be true, because of cheap low price (other more established brand smart rings are selling for $ 160 +) Also wont help that by quick google search regarding smart rings found same ring with different brand and same images - https://www.colmi.info/products/colmi

Yep I already got a few of these Colmi rings (by a few I mean too many XD) I tried a few things with them, first I tried decompiling the firmware that ATC1441 extracted (see this interesting GH repo here: link) with ghidra to play around with the stock settings (accel range, advertising interval) bu

This looks like a Colmi ring that can be found for cheap on AliExpress. So yes, scam. Can be bought for $20

it's a scam. The ring is a cheap colmi variant, the measurement of bp is a false claim for most of the rings in general, but for that one especially. There are very, very few rings with cuffless bp measurements and no colmi ring is among them.

I mean, there are cheaper rings out there. J-style rings, colmi ring, clone rings of j-style, whatever. They are cheaper - but quality of sensors seems to be poorer on them, and support quite often is non-existent.

None of the Colmi rings are accurate with regularity, but even a broken clock is right twice a day. The sensors that go into the Colmi rings (and other clones) are so outdated that they no longer have any real commercial value...which is why the rings are so cheap. The high DOA rate and short life o

As with all of the rest of the rings on this list, the Haale and Haale II are "white label" rings that have been licensed from China...in other words, a "clone." Clones are not copies, they are the same, identical devices. The specific device may vary with the examples above, but I will specify here

I would like to know too, I am currently using the Colmi Rings R9. Tracks well but the app is not good deletes data and cannot change or add sleep and menstrual data.
