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

Smart ring options besides Ringconn and Ultrahuman?

I have a cheap Colmi Ring, heart rate, steps and sleeping is quite accurate, battery last 5 days and has been quite reliable, super happy for now. Cost around 25usd

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.

Which smart ring is best for me? Off brand TikTok/amazon/temu ring effective?

I lost my Ringconn Gen 2, I lost a lot of weight and slid off my finger. Since I cannot afford a New Ringconn, I ordered a Tik Tok cheap smart ring. The Colmi R02. The sleep tracking, heart rate, HRV closely match my Apple Watch. The ring does not detect naps. For the price point, it is not bad.

Least, expensive smart ring

I would think the Colmi R02 would be the cheapest of the recommends.

Looking for an affordable smart ring - first time buyer!

I only just started with a smart ring and I read somewhere that a cheap ring is a good idea to test whether you’re likely to stick with wearing a smart ring during the day and when sleeping, checking your stats etc. I bought a cheap Colmi ring (r09 model) for less than $50, and so far so good. Of co

New to smart rings

I get shoulder taps all the time and it will be great for me to remember what tickets I need to create and do.I have been looking at actual smart rings here as well and decided I

Talk me our of getting a Colmi ring

I have a Colmi R02 that I got off of eBay for $25 shipped. It's my gateway to other rings and I recommend it. The RO2 doesn't do steps. Not that i have seen. I will go back and check again. I still like the silly little thing and it's going to my Wife when my Fitaos R05 arrives this week.
