Inllie Luna Core and Sense Core: “invisible” fitness trackers

While the big manufacturers of wearable electronics continue to increase the diagonals of displays, add new sports modes and turn smart watches into miniature smartphones on the wrist, the Inllie brand has chosen the opposite approach. The company introduced the Luna Core Bracelet and Sense Core Band – devices that try to incorporate fitness functions into the format of everyday jewelry, rather than sports gadgets.

The new models are aimed at an audience for which health monitoring is important, but at the same time they do not like the aesthetics of traditional fitness bracelets with plastic cases, massive frames and constantly glowing screens. At Inllie, they are betting on minimalism and the idea of ​​”invisible” electronics that do not attract too much attention in everyday life.

Minimalist design instead of typical sports style

Luna Core Bracelet looks more like a designer bracelet than a fitness tracker. The body is made of zinc alloy and epoxy resin, and the metal bracelet is complemented by decorative elements with gold and silver decoration. The manufacturer deliberately abandoned the display in order to keep the appearance as close as possible to a regular accessory.

This approach is becoming more and more popular among brands working in the fashion-tech segment, where wearable electronics ceases to be a demonstration of technology and becomes part of everyday style. In the case of Luna Core, the user does not interact with the device directly at all – all information is displayed only in the mobile application.

At the same time, the construction remains very light. The weight of the device is 11.6 grams, thanks to which the bracelet is practically not felt on the hand even when worn for a long time.

Sense Core Band keeps the general concept, but already offers a little more functionality. The device received a thin body with a width of 5.6 mm and a compact screen that displays only basic data – time, heart rate and battery level. Such a display does not turn the bracelet into a full-fledged smart watch, but rather acts as a small information indicator.

The manufacturer also emphasized customization. Different types of straps are available for the Sense Core, from metal options in the style of Milanese weaving to silicone solutions for more practical everyday use.

Hidden health monitoring

Despite the external simplicity, inside the devices there is a standard set of sensors typical for modern mid-range fitness trackers. Both gadgets are capable of 24/7 heart rate monitoring, blood oxygen level measurement, and heart rate variability analysis.

The devices are also able to record the level of stress, analyze the quality of sleep and track the user’s daily activity. The functions of counting steps, estimating the total physical load and basic training modes are supported.

However, Inllie is clearly not trying to compete with a professional sports watch like Garmin or Polar. There is no emphasis on complex training analytics, navigation or advanced sports metrics. The main idea is precisely the background monitoring of the body’s condition without the need to constantly interact with the device.

Actually, the company tries to occupy an intermediate niche between traditional jewelry and classic fitness bracelets, where technology becomes less intrusive and visually almost invisible.

Autonomy without daily charging

One of the main problems of compact wearable electronics has traditionally been limited battery space. However, Inllie claims that the Luna Core Bracelet can last five to seven days without recharging, depending on the intensity of sensor usage.

Sense Core Band shows similar performance, although the presence of the display slightly reduces autonomy. In standby mode, both models can work for about ten to twelve days.

For devices of this format, this is a fairly balanced result. The manufacturer had to find a compromise between the compact size of the case, the lightness of the design and the battery life.

Price of Luna Core Bracelet and Sense Core Band

The Luna Core Bracelet is priced at $149, while the Sense Core Band is priced at $109. The company also offers a bundle of two devices at a discount for buyers who want to buy both models at the same time.
