Design and Build Quality

The Cubot C21 is engineered with a focus on simplicity and functionality. Its compact design features dimensions of 46.5 x 46.5 x 13 mm, making it quite suitable for users who prefer smaller and more comfortable devices. The choice of materials, such as the zinc alloy frame, adds to the durability and robustness of the wearable device, ensuring that it not only looks elegant but can also withstand everyday use. The square-shaped frame gives it a modern edge, while the use of Corning Gorilla Glass provides essential screen protection against scratches and minor impacts, maintaining its aesthetic appeal over time.

Display

The device boasts a 1.32-inch TFT LCD display with a resolution of 360 x 360 pixels. This translates to a pixel density of approximately 386 ppi, providing clear and sharp visuals that are bright enough for indoor and outdoor environments. Despite its budget-friendly price tag, the device does a commendable job of ensuring that visuals are vivid and text is easy to read, which enhances the overall user experience, particularly for quick glances at notifications and other information.

Software and Performance

Running on a proprietary OS, the Cubot C21 is designed to perform efficiently within the limits of its hardware specifications. While not offering high-end processing power, it efficiently handles the basic functionalities needed in a wearable device. The interface is straightforward and user-friendly, making it accessible even for users who are new to smart wearables. The core functionalities, such as fitness tracking and health monitoring, are integrated smoothly within the software, offering a seamless experience for daily use.

Battery Life

Equipped with a 300 mAh non-removable battery, the Cubot C21 is optimized for long-lasting battery life given its modest hardware. This capacity is well-suited to support the device through a full day of typical use, including health monitoring and regular notifications. Given the small screen size and efficient use of resources, users can expect reliable performance without frequent charging interruptions, making it suitable for both daily wear and more extended usage periods.

Health and Fitness Features

The Cubot C21 emphasizes health monitoring features, which are becoming increasingly important in wearable technology. It includes sensors for heart rate, SpO2, and blood pressure monitoring, allowing users to keep a closer check on their vital signs. These features cater to users who are health-conscious and want to stay informed about their physical well-being easily. The inclusion of an accelerometer further aids in tracking movement-related data, which is essential for fitness tracking applications.

Connectivity

When it comes to connectivity, the Cubot C21 focuses on simplicity. It features Bluetooth 5.0 with A2DP, allowing it to pair with a smartphone or Bluetooth-enabled device for notifications and media control. However, it lacks Wi-Fi and cellular connectivity, which means it relies on a connected smartphone for all data-related functionalities. This can be seen as a limitation but also helps in pushing battery performance, a critical factor in wearable devices.

Storage and Multimedia

The Cubot C21 offers 128MB of internal storage, which is sufficient for installing and running a basic set of applications designed for the device. However, it does not feature a card slot for expandable memory, which means users are confined to the onboard storage capacity. While informed users may need to manage storage space efficiently, this amount of memory is quite common among devices within its price range.

Sound and Audio

The device does not come with a loudspeaker or a 3.5mm audio jack, focusing on its core function as a wearable tech rather than a multimedia device. Audio alerts and other sound functionalities are usually managed through the connected smartphone, keeping the device simple and focused on its primary health and notification functions.

Price and Availability

Released in November 2023, the Cubot C21 is available in Black and Silver, and carries an approximate cost of 40 EUR, positioning it as an affordable entry into the smartwatch market. Its price point makes it an attractive option for budget-conscious consumers looking for essential smartwatch features without the premium cost. This affordability, combined with its efficient functionality, makes it a pragmatic choice for users seeking a balance between cost and utility.
