R02

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.

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 The sensors that go into the Colmi rings (and other clones) are so outdated that they no longer have any real commercial value...which is why the rings are so cheap.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

I use the R09 because it's the nicest of the Colmi rings (I like the nubs for the sensors for locating ring position) and temperature sensor. Colmi rings are the only smart rings that work with Gadgetbridge, so if you are active at all in the privacy and open source community, they're really the onl

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 have a Colmi R09 and R02. 09 is slightly more accurate, but battery lasts about 2 days. 02 is a bit less accurate but "good enough" for me for sleep, activity, and exercise tracking and battery lasts over 4 days.

I have a colmi R09 and R02 for over a year now. I first purchase the R02 it worked great except the gold exterior is scratching away but the app and accuracy have been great as I have compared it with my Apple Watch. The R09 has a has temperature sensor and it’s what told me that I had a fever sever

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

I thought the colmi ring was pretty impressive for like $20. Tested it against my fenix and an Apple Watch and for steps and sleep i thought it did a pretty good job. Nothing advanced, but you get a lot of value for what you pay. Syncs with Apple health too. My plan was to test it out and if i liked

Look for the Colmi rings thaf use the QRing app if accuracy doesn't matter. But buy several extras as they do sometimes arrive dead on arrival. Look on Temu or Ali for R06, R07, R09, or R10. You could even mix and match as the hardware is identical except the 9 supposedly adds a skin temp sensor.
