Whether you’re running like you’re late for coffee, cycling to nowhere on a stationary bike, or attempting yoga poses you saw on Instagram, it’s got multiple sport modes to track your epic (or not so epic) workouts.

Fitness Tracker Smart Ring
Joshua W.
Cardiff
April 26, 2025
As an impulsive buyer, I picked this up on a whim during a sale, thinking it'd be a cool gadget to help with my fitness goals while juggling studies and family life here in Cardiff. I've been using it for a couple of months now, and it's been a mixed bag. On one hand, I love how sleek it looks—no one even notices it's a tracker, which is great for someone like me who travels a lot and hates bulky wearables. It tracks my steps and sleep fairly well, and the app integration is smooth with my Android device, giving me insights into my daily habits without much fuss. But, it is what it is, the readings for things like blood pressure and oxygen levels seem off at times, making me question their reliability. During a recent trip, I wore it for a hike, and it didn't accurately capture the distance or calories burned, which was a letdown. Plus, with a young child at home, I need something dependable, and this feels a bit hit-or-miss. Overall, it's a decent accessory for casual use, but if you're serious about health tracking, you might want to look elsewhere. I'd say it's okay, but not amazing.
- Pros: I was fairly impressed with how comfortable and discreet it is to wear all day, blending in like a regular ring while still tracking my heart and sleep patterns. The battery lasts a long time, and I appreciate that it works with my phone without any extra costs, making it easy to check my stats on the go.
- Cons: From what I feel, the accuracy isn't always spot-on, especially during intense activities, and it can be a bit glitchy when syncing data. The charging case is handy, but the ring itself feels a bit fragile, and I've had some issues with it not picking up all my movements correctly, which is frustrating when you're trying to stay on top of things.
