Fittr Hart X2 Smart Ring Review: Fitness Tracking in a Tiny Package

New Delhi – If you’ve been into fitness for a while, you’ve probably heard of Fittr, the app-based fitness community started by Jitendra Chouksey. After launching a smart scale some time back, the brand is now stepping into wearable tech with its latest gadget, the Fittr Hart X2 smart ring. At Rs 19,499, it doesn’t come cheap, so the obvious question is: is it really worth ditching your smartwatch or fitness band for this little ring?

First Impressions and Design

Buying a smart ring is a bit different from buying a watch or tracker. You need the right size, and Fittr sends you a sizing kit before shipping the actual product. It’s best to go slightly loose rather than a snug fit so the sensors sit comfortably under your finger.

The ring is sleek, made of titanium, and comes in black, gold, and silver with a shiny finish. Personally, the black one looks the best, classy but not flashy. It’s light, scratch-resistant, and even comes with a charging case that doubles as a portable battery pack, so you can top up on the go. Plus, with 5ATM water resistance, you can wear it all day, even for a swim, without worrying.

What It Can Do

Despite its size, the Hart X2 is packed with sensors. It tracks your sleep, heart rate, oxygen levels, calories burnt, activity, VO2 Max, stress, and even skin temperature. The experience feels very different from smartwatches because there’s no screen – it quietly gathers data in the background while you go about your day.

Everything is synced to the Fittr Hart app on iOS or Android, and syncing is quick via Bluetooth 5.0. The ring can also store data for two weeks if you forget to connect it.

In daily use, sleep tracking stood out as the most accurate and useful feature. It not only shows when you were in deep, REM, or light sleep but also gives a score and simple advice to improve your rest. Step and activity tracking works well too, especially if you’re into running or walking. Heart rate and SpO₂ results were consistent, though skin temperature and stress levels often felt unreliable.

Battery and Usability

The Hart X2 lasts about a week per charge, which is decent for such a tiny device. The case can recharge the ring once or twice without being plugged in, and charging is fairly quick altogether.

Should You Buy It?

Here’s the bottom line: the Fittr Hart X2 isn’t trying to replace your smartwatch. Instead, it’s a discreet little health companion focused purely on fitness and recovery. Yes, it’s pricey, but it delivers meaningful insights instead of just flooding you with numbers. If you’re serious about health tracking but don’t want to spend Apple Watch money, this smart ring is definitely worth a look.
