Review: Great for the Price and Battery Life - I've been wearing my RingConn Gen 2 (basic $199 model) for three weeks, and I love it. You can't beat the price, no-monthly subscription, and long battery life (10 days has been accurate for me so far). I purchased the basic Gen 2 model to start because I frequently wash my hands and garden, so I wanted to ensure the ring could outlast me, and so far so good. I've worn an Apple watch for a decade, but I have trouble wearing it at night for sleep tracking, and I am tired of wearing a bulky item on my wrist. The RingConn is lightweight, I hardly notice it especially while sleeping so I can finally track my sleep. I purchased the Dune Gold, which I would consider similar to a rose gold, and it looks classy; not cheap-looking at all. I also purchased the RingConn ring sizing kit prior to making this purchase to ensure I purchased the right size. I definitely recommend taking this extra step so the ring fits just as you imagine. The sizing kit includes a booklet that mentions you should wear this ring on your non-dominant hand and recommends your index and middle finger, although I've heard it's less about what finger you use and more about consistently wearing it for proper data tracking. I've read some people have issues with the app. I find the app and data to be easy to access and helpful. I have it setup to communicate with my other health apps (like My Fitness Pal, Apple Health) so everything syncs together. The only weird issue I'm noticing is my activity steps on the RingConn app are typically 500-1,000 steps higher than what my other health apps are syncing. Not sure why this is happening, maybe a me thing, but it doesn't bother me. I should also mention I don't have the RingConn app running all the time in the background; I manually sync it throughout the day by simply opening the app. This difference might be why I'm getting such good battery life opposed to some other users. Overall if you're thinking about getting a fitness ring, and don't want to spend a lot of money to start, purchase this model.
Review: No Subscription Required - I chose the RingConn Gen 2 Air mainly because it does not require a subscription and was less expensive than competitors over time. That alone made it much easier to justify financially. The ring feels lightweight and comfortable enough to wear during sleep, workouts, and normal daily activities without becoming distracting. The tracking also seems accurate in regular use, and the battery life has been solid so far. The app is straightforward and functional without feeling overly cluttered or confusing. I also appreciated being able to access features without being locked behind a monthly paywall. I put a protective cover on the ring immediately, so I cannot really comment on scratch resistance yet. Overall, though, it feels like a strong value for people who want health tracking without an ongoing subscription cost. I would recommend it and buy it again.

## Features

- [Size Before You Buy] Before purchasing the RingConn Smart Ring, we highly recommend acquiring the RingConn Sizing Kit to determine the most comfortable and suitable size for your finger. Please note that the RingConn Sizing Kit is only compatible with the RingConn Smart Ring
- [Not Standard Sizing] RingConn Smart Ring differs from standard rings as it contains sensors on the inside. Therefore, we recommend using the RingConn Sizing Kit to determine the best fit. The RingConn Smart Ring is available in sizes 6 to 14, accommodating various finger sizes
- [How to Measure & Fit Check] Wear the sizing gauge snugly around the base of your finger, ensuring it doesn’t rotate freely. We recommend wearing it for over 24 hours to determine your most accurate fit. For optimal data and comfort, the RingConn Smart Ring should fit snugly against your skin without rotating. When testing for the best size, make sure the sizing gauge remains tight around the base of your finger
- [Choose a Finger] The RingConn Smart Ring can be worn on any finger and on either hand. For optimal accuracy and comfort, we recommend wearing the RingConn Smart Ring on your index, middle, or ring finger. Be sure to size the exact finger on which you plan to wear your RingConn Smart Ring for the best fit
- [Manufacturing Quality] RingConn Sizing Kit is made from premium-grade plastic, while the RingConn Smart Ring is crafted from aerospace-grade titanium, coated with a scratch-resistant layer for outstanding corrosion resistance and durability

### ⭐⭐⭐⭐⭐ The best no subscription tracking ring.
*by J***E on August 13, 2026*

Phenomenal. Had an issue with the battery after a year and a few months and they replaced the ring. Great tracking features and overall amazing product. It’s easy to use and charge. The best part is having a company that truly values their customers!!!
