Smart Ring by Jermisdin
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

Suggestions for a starter Smart Ring please!
I am using the Colmi R02 as my starter ring and it has taught me a lot. It was really inexpensive to get. At first it was my gateway ring until I got my Pebble Index 01. Instead it has become a learning tool to see what it can show me over even my smartwatch. So i do recommend it as a cheap way to g

Talk me our of getting a Colmi ring
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.

Smart ring options besides Ringconn and Ultrahuman?

Inexpensive smart ring that syncs to Apple Health?
Thanks! Was just on Amazon and saw the COLMI R02 and seemed legit. Qring app seems to write to Apple health easily enough.

Help! Website needs review. Spent $150 on ads and no add to carts.
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

Would anyone be interested in an open-source smart ring platform?
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

Best Budget Ring
I recently discovered the Colmi rings. I went with R09. I haven’t tried more expensive brands or those with newer tech. But mine seems fairly accurate for sleep. I’m happy and see no reason to upgrade for now. But if I do, it’s likely to be a Ringconn.

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