Ever wondered if you really need a bulky smartwatch to track your health? Enter the Fittr Hart X2, a sleek smart ring designed to track your sleep, heart rate, SpO2, stress, and daily activity-all while looking like a stylish piece of jewelry. Unlike smartwatches that need daily charging, the Hart X2 lasts up to 8 days on a single charge.

Made of titanium and available in Gun Metal Black, Sterling Gold, and Frost Silver, this ring feels comfortable and light, even for sensitive skin. Its water-resistant design means you can shower or swim without removing it, a feature that sets it apart from most fitness trackers.

The biggest highlight? Sleep tracking. For frequent travelers or people with irregular schedules, the Hart X2 captures sleep stages, wake times, and efficiency accurately. The companion app presents all your health metrics visually, so you can track trends over time.

Perfect for casual fitness enthusiasts who want discreet, subscription-free health tracking, the Fittr Hart X2 proves that sometimes, less really is more—all in a ring you can forget you’re wearing.
