RENPHO LYNX Lynx Smart Ring: Get the Perfect Fit with Sizing Kit
Meet the RENPHO Lynx Smart Ring—your new fitness buddy that doesn't just sit there looking pretty (though, let's be honest, its sleek titanium design is a head-turner). Whether you're a gym enthusiast or someone who just wants to keep tabs on their health without the hassle, this ring's got your back. And yes, it's waterproof, so go ahead, wear it in the shower or while you're pretending to swim laps in the pool.
But it's not just about looking good or surviving water encounters. This little powerhouse dishes out the dirt on your sleep, keeps an eye on your blood oxygen levels, and even tells you when you're stressing out (because sometimes you need a gadget to point out the obvious). Plus, it tracks your heart rate, steps, how far you've wandered, and how many calories you've burned—probably while thinking about pizza.
Here's the kicker: it lasts a whole week on a single charge, and there's a charging case included because losing the charger is practically a sport. Perfect for those who travel or just can't be bothered to charge things every other day.
Oh, and before I forget:
- No sneaky subscription fees—just download the Renpho Health App and you're golden.
- Plays nice with Apple Health and Google Health Connect, because exclusivity is so last season.
- Rated 5ATM waterproof, meaning it can handle your day, rain or shine (or accidental dunk in the toilet).
- And for the health-conscious shoppers, it's HSA/FSA eligible. Because your health should be an investment, not just an expense.
- Comprehensive health and fitness insights
- No Subscription Fees

Lynx Smart Ring
Isabella W.
Manchester
June 20, 2025
Before getting this ring, I was using a basic fitness tracker that felt bulky and required daily charging—it was a hassle, especially with my busy military schedule. I bought this on an impulse because I liked the idea of something discreet and stylish. After using it for a couple of weeks, I've noticed a big improvement in keeping tabs on my health without extra effort. It tracks my steps, distance, and calories burned pretty well, and I appreciate the blood oxygen and sleep insights, though they're not perfect. The no-subscription fee is a huge plus, saving me money in the long run. Overall, despite some hiccups, it's a solid upgrade that fits my lifestyle, and I'd recommend it to others looking for a convenient health tool.
- Pros: The design is extremely sleek and lightweight, making it comfortable to wear all day without any irritation. I love that it lasts a whole week on a single charge, which is pretty decent for someone like me who's always on the go. The included charging case is a lifesaver, preventing me from losing it. It's also waterproof, so I can wear it in the shower or during workouts without worrying. From what I feel, the app is easy to use and connects well with my other health apps, giving me a clear view of my data without any extra costs.
