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

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

Hello, thanks for offering to participate in this feedback exchange. I did my review and first impressions on your iOS app. To answer your questions First impressions. Visually, I think you show from first impressions that you are not some shmo making an app, but took time to make sure that the desi

That is more useful than anything I had, thank you. The separate state machine explains something that has been bothering me for months: an interrupted bulk sync on my side does not fail cleanly, it comes back as a partial night attributed to the wrong day. I had a workaround for the symptom and no

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
