Zepp Health has expanded its lineup of minimalist fitness wearables with a new option designed for people who want tracking without the bulk of a traditional smartwatch. Called the Amazfit Helio Core, it’s essentially a wearable module rather than a full device, giving buyers more flexibility in how they wear it and potentially helping them cut costs compared to an all-in-one wearable.
If you’ve heard of the Amazfit Helio, you’ll know the idea: a fitness-focused wearable that skips the display. That no-screen design can be a real advantage for athletes who don’t want distractions mid-workout, and it may also be more acceptable in certain competitions where typical smartwatches aren’t allowed. The new Helio Core takes that concept even further by selling the sensor unit on its own.
In the US, the Amazfit Helio Core is priced at $70 and comes in three color variants: FireCore, SpiritCore, and NeonCore. There’s an important catch, though: the module doesn’t include the required charging base or a compatible Helio strap in the box. In other words, you’re buying the “brains and sensors” only, not a ready-to-wear package.
So what exactly is the Helio Core? It’s a compact sensor unit that includes the core components you’d expect for fitness tracking, including a processor, onboard storage, and Bluetooth for syncing with your phone. The real appeal is how it can be used. Instead of being limited to a wristwatch format, the module can potentially be worn in different ways—under a sweatband, attached to a strap you might use for carrying a smartphone, or even positioned elsewhere on the body. For example, wearing it on a leg could make sense for gym sessions where lower-body movement is the focus.
Zepp Health hasn’t been fully clear about who the Helio Core is meant for, but a few possibilities stand out. It could appeal to people who like customizing their workout gear, athletes who want an ultra-low-profile tracker, or users who want a modular approach where they can choose accessories separately rather than paying for a complete wearable bundle. There’s also the possibility that the module could be integrated into other proprietary wearables or setups down the line.
As for availability beyond the US, details are still up in the air. It’s currently unclear if the Helio Core will launch in additional markets, or what pricing would look like internationally. For shoppers who prefer a more traditional “ready to wear” solution, there’s also a Helio strap option sold separately, which effectively turns the module into a standard wearable once you add the necessary accessories.
With the Helio Core, Zepp Health is leaning into a growing trend in fitness tech: less screen time, more data, and more ways to wear your tracker the way you want—whether you’re training, competing, or just trying to keep your workouts distraction-free.
