Scratches Easily
I love everything about this ring so far. The comfort, the battery life, the accuracy etc. It is awesome other than it scratches very easily. I go out of my way to “protect” it but it gets scratched with regular wear.EDIT: customer service has gone above and beyond what was expected to resolve the situation. As I stated above, the ring is phenomenal. I am more than happy with its performance.

Comfortable, Discreet Fitness Tracking with Solid Everyday Performance
After getting tired of bulky fitness trackers, I switched to this smart ring and it’s been much more comfortable for daily use. It’s lightweight and smooth, so I barely notice it during the day or while sleeping. The setup with my phone was simple, and it syncs reliably with both Android and iOS.It tracks basics like steps, heart rate, sleep, and stress, and the data seems fairly consistent for everyday monitoring. Battery life is close to the advertised range. I get about 5–6 days per charge. The women’s health tracking is a helpful extra feature.It’s not as detailed as high end smartwatches, but that’s expected at this size. Overall, a convenient and discreet option if you want simple health tracking without wearing a watch.

simple way to stay active
With the O Ring on, I head out for my walk. Today, I went to the nearby park for a 30-minute brisk walk. The ring instantly tracked my steps, distance, and calories burned. As I walked along the path, I glanced at the three-ring display: the outer ring for steps, the middle for distance, and the inner for calories. Watching each ring gradually fill gave me a small sense of accomplishment and kept me motivated throughout. After the walk, I spent 15 minutes stretching and doing a few yoga poses. The ring recorded these movements as well, giving a clear picture of total activity and energy spent. At the end of the session, it provided a summary showing steps taken, kilometers walked, and calories burned. Seeing all the numbers together made me feel productive and encouraged me to stay active. Later, while sitting at my desk, the ring continued tracking my remaining steps. It offered gentle nudges to move or stretch, helping me avoid long periods of inactivity. In the evening, checking the weekly trends in the app helped me plan workouts more effectively and maintain steady progress toward my activity goals.

Light ring that blends into daily tracking
Slides onto the finger before heading out, then gets rotated slightly until the inner edge sits flat without shifting around. Later in the day, a quick glance at the app shows steps and heart rate already logged without needing to press anything, and the ring stays on through hand washing without being taken off. Before bed, it gets adjusted once more to a tighter position so it doesn’t move overnight, then checked again in the morning where sleep segments and timing are already recorded. The surface feels smooth and doesn’t snag during regular use, though sizing takes a bit of trial since it fits differently than standard rings. Battery holds through daily wear without needing constant attention, and nothing interrupts the routine once it’s on. Ends up becoming part of the day without much thought after the first couple of uses.

Does not connect
Does not connect to my iPhone even when fully charged. App is buggy and does nothing when you click on “Start”.

Stylish and practical to wear.
This smart ring is perfect for people like me who don’t want to be tied down by devices. It’s very discreet; it doesn’t get in the way when typing, using my phone, or doing housework, and I don’t constantly notice it on my wrist, yet it still tracks my schedule and activity level.Pairing was smooth from the start, and once connected to my phone, I basically don’t need to worry about it anymore. I just go about my normal life each day, checking the app in the evening to see the data, like sleep or activity levels, to get a general idea of my status. Sometimes seeing the data reminds me to get some rest, which is a small form of self management.The battery life is also good; I love that I don’t need to charge it every day. It only needs charging every few days, so it doesn’t disrupt my routine. After wearing it for a while, it’s become a habit, and I feel like something’s missing if I don’t wear it. Overall, it’s very easy to use, requiring no time for figuring out or adjusting.

comfort all day
Wearing the O Ring throughout the day has been surprisingly comfortable. The titanium alloy feels light on my finger, and I often forget it is even there. It stays in place perfectly while I type, cook, or exercise, so I never have to adjust it constantly. I especially value how it tracks health data quietly in the background. Heart rate, stress levels, and activity are recorded continuously without any interruption. Checking the app in the evening gives me a clear picture of how my body responded during the day, and the information feels personal and informative rather than overwhelming. Charging is simple and infrequent. With up to seven days of battery life, I can focus on my day without worrying about the ring running out of power. Even after showers and handwashing, it continues to function flawlessly, which adds to the comfort of wearing it day and night. The O Ring blends seamlessly into daily life. Its design and performance make it easy to keep health tracking in view without feeling heavy or intrusive. Wearing it has become part of my day naturally, and I find the experience smooth and unobtrusive.

Light enough to forget I am wearing it
I have tried several fitness trackers over the years but I always ended up taking them off because they felt bulky on my wrist. This ring is different. It is so light that I forget I have it on after a few minutes. The band is smooth and does not leave any marks on my finger. It tracks my sleep and stress levels without me having to do anything. The heart rate monitoring seems accurate compared to my chest strap.I also like that it tracks women’s health which is not something most fitness rings include. The battery lasts me about six days on a full charge. The charging case is small and easy to pack for trips. The data shows up clearly in the app without too much clutter.
