Hivisuals R-18 Smart Ring with Charging Box: 24-hour heart rate monitoring
Meet the Hivisuals Smart Ring—your new 24/7 health buddy that's as stylish as it is smart. This isn't just any wearable; it's like having a mini health lab on your finger, tracking everything from your heart rate to how much oxygen is in your blood, plus counting those steps and calories like a pro. And the best part? All this juicy data zips straight to your phone with no pesky subscription fees.
But wait, there's more (because of course there is):
- It's got your back (or rather, your finger) with round-the-clock health checks, keeping tabs on your heart and blood oxygen levels.
- Whether you're running, yoga-ing, or just chasing your dog around the park, it's got a mode for that.
- So comfy you'll forget it's there—until it reminds you to move, that is.
- It even plays sleep detective, analyzing your z's to help you catch more of them.
- And because we know you're busy, it comes with a charging case that's as portable as your keys.
Works with Android 6.0 and iOS 10.0 or newer, making it the perfect mashup of tech and fashion. Because who says you can't have both?

Smart Ring with Charging Box
Siddharth K.
Mumbai
June 23, 2025
i had high expectations for this ring, given my background in engineering and my perfectionist nature—i thought it would be a seamless health tool. in reality, while it looks stylish and is comfortable, the performance falls short in key areas. for instance, during my daily walks or when i attend concerts, the tracking seems off, and i've had to double-check the numbers manually. it's frustrating because i wanted something reliable for monitoring my health metrics over time. on the positive side, the sleep tracking has been helpful, and i like that it doesn't add any extra costs. overall, it's a decent device but not the flawless experience i was hoping for, which leaves me feeling a bit let down.
- Pros: the ring is incredibly comfortable to wear all day and night, and i appreciate that it tracks my heart rate and blood oxygen continuously without needing a subscription. the charging case is small and easy to carry, making it convenient for travel. it pairs well with my phone, and the sleep analysis has given me some useful insights into my rest patterns.
- Cons: as it seemed to me, the step and calorie counting can be inaccurate at times, especially during intense activities, which is disappointing for someone who values precision. the alerts to move can feel intrusive, and the battery life doesn't always last as long as i'd hoped, requiring frequent charges. also, the data sync isn't always instant, leading to delays in seeing updates.
