Naughtbaby 3 Pro Smart Ring Health & Fitness Tracker: Fitness Companion with subscription-free app
Meet the FitElf 3 Pro Smart Ring—your new fitness buddy that doesn't care about gender but is all about keeping you in the loop on your health. It's like having a mini doctor on your finger, minus the awkward small talk, tracking everything from your heart rate to how well you're sleeping (or not sleeping, no judgment here). And yes, it's IP68 waterproof, so go ahead, take it for a swim; it's got your back (or rather, your finger). With a 10-day battery life and a magnetic charging case that's like a power nap for your ring, you're set for the long haul.
But wait, there's more (said in my best infomercial voice):
- Whether you're running in the park or pretending to run on a treadmill, it gives you real-time updates because it loves to cheer you on.
- It breaks down your sleep into stages—deep sleep, light sleep, REM—because it's nosy about how you recharge.
- For the ladies, it even keeps tabs on your menstrual cycle, because why should you have to remember everything?
- Setting it up is a breeze with Android 6.0+ and iOS 11.0+ smartphones. If you can send a text, you can set this up.
- 24/7 Wellness Monitor for heart rate and calories
- Smart Sleep Tracker with detailed sleep stages
- Long-Lasting Power with 10+ days battery life
- Inclusive Health Tracking for all genders

When I first got this Naughtbaby ring, I had high hopes based on the description. I thought it would be like having a mini doctor on my finger, but the reality fell short in some ways. The heart rate tracking is generally good, but during intense activities, it sometimes lags, which is frustrating for someone who values precision. Sleep analysis is detailed, breaking things into stages, but I've noticed inconsistencies that make me doubt its accuracy. On the plus side, the waterproof feature is awesome—I've worn it swimming without issues, and the battery life is impressive, lasting over a week. The menstrual cycle tracking is a helpful addition, though I wish it integrated better with other apps I use. Overall, it's a decent device, but as a software developer, I expected more seamless performance and finer details. It's not perfect, but it does the job for basic health monitoring.
- Pros: I expected this ring to be awesome for tracking my health and it seemed super accurate with heart rate and sleep stages. The battery lasts a long time and it's great for swimming, which I love since I enjoy water activities. Setting it up was easy with my phone, and I liked that it could monitor my cycle without me having to remember everything.
- Cons: As a perfectionist, I was disappointed because it didn't meet all my expectations. The real-time updates during workouts felt a bit delayed at times, and the sleep tracking seemed off occasionally, making me question its reliability. The magnetic charging case is convenient but the ring itself feels a bit bulky on my finger, which I didn't anticipate.
