MZJ Smart Ring Fitness Tracker for iOS & Android – Sleep Monitor Heart Rate Blood Oxygen & Pressure 8 Sports Modes IP68 Waterproof NO Subscription Long Battery Life (Titanium Silver, 12#)

The Smart Ring Fitness Tracker in Champagne Gold is an incredible blend of style and technology. Unlike bulky watches, this ring is sleek, lightweight, and looks like a piece of jewelry while still delivering powerful tracking features. It’s comfortable enough to wear all day and night, making it easy to collect accurate health and fitness data without interruption. Functionality is where this ring shines. It continuously monitors heart rate, blood oxygen, blood pressure, and sleep quality, giving me a complete picture of my health. The sleep monitor is especially impressive—it tracks deep, light, and REM stages so I can understand and improve my rest. The inclusion of 8 sports modes makes it versatile, whether I’m running, cycling, or just walking. I love that it’s IP68 waterproof, which means I don’t have to take it off when washing hands, working out, or even swimming. The long battery life is another major plus; it easily lasts several days on a single charge, unlike many smartwatches that need daily charging. The Bluetooth app connection is smooth and reliable, syncing quickly with both iOS and Android. The app provides clear charts and insights, helping me stay on top of my health goals. Best of all, there are no subscription fees, so all features are available without hidden costs. Overall, this smart ring is stylish, practical, and packed with features. It’s perfect for anyone who wants a discreet yet powerful way to track health and fitness. A great alternative to watches and bands

I received the Smart Ring Fitness Tracker well-packaged and in perfect condition. From the start, you can tell it’s made with high-quality materials, and the Champagne Gold color looks elegant and modern. It works exactly as described — accurately tracking heart rate, blood oxygen, blood pressure, sleep, and steps. Pairing with my iPhone was quick and easy. I love that it doesn’t require a subscription, and the battery lasts for several days. An excellent purchase — highly recommended!

Liked the ring and app while it worked. Stopped updating to app about 2 months after getting

It was shipped instantly, arrived on time. DIfficulty getting this to hook up at first through my wifi network but finally did. I wasn't keen on the user interface and it really didn't offer more data than I'm already getting on my apple watch. I thought it would do real live tracking and I had to activate the "start" command each time to take BPM. So, not to keen on keeping this one and will look for Ultrahuman or something that still doesn't require a subscription. If one wants a simple report, minimal data, this is probably good for you.

Very inaccurate. I owned an Oura before but it stopped charging after 3 years of use. I didn’t want to spend the money and keep the subscription so I tried this one. I wasted my money! It does not do hrv-heart rate variability and the sleep tracking is very inaccurate. I couldn’t trust the bp or anything else after that.

I’m so glad I got this. I was about to buy the Oura ring but couldn’t justify the monthly fee. This one does everything I need — tracks my heart rate, sleep, blood pressure, workouts — and NO subscription. Just a one-time buy and done. The app is super easy to use, battery life is solid, and it charges fast. I’ve even used it to take pics with my phone, which was kinda fun lol. Definitely recommend measuring your finger first though, I almost guessed and that would’ve been dumb. Love this thing. I feel like I’m finally paying attention to my health without paying extra every month

Love this! Measures well and stays charged for at least a week. I have a friend that bought the $400 ring and she like mine better. It shows every scratch but still doesn’t look terrible. Definitely worth the money.

This tracks very closely with my Galaxy Watch, which is great. It looked nearly identical to my wedding band so I just wear it as such. It's very lightweight and I've had no issues with it working after showers, swim, etc. Great value and the size was spot on with what I ordered.

The only one that can be calibrated and is still consistent. Really impressed and I am a doctor
