The brand’s origins are associated with 2002, while corporate registration records indicate that the current legal entity, Shenzhen Lefu Weighing Apparatus Co., Ltd., was established on June 22, 2010. 2 The company’s roots lie in traditional weighing equipment and electronic scales. Over time, its operations expanded from conventional weighing products to include smart body-composition measurement and broader weight-management solutions.

According to company-reported figures, LEFU has approximately 15 years of experience in the body-fat scale sector. The company states it serves around 3 million users, maintains an annual production capacity exceeding 15 million units, and distributes products in more than 80 countries. These statistics are self-reported by the brand. 1

LEFU’s strategic positioning centres on “weight management” rather than simple weighing. The company offers a solution suite that connects several areas:

• Smart weighing
• Body-fat and body-composition measurement
• Food and calorie measurement
• Weight-management software
• Low-calorie and low-sugar food recommendations
• Health-oriented ingredients
• Nutritionist services
• AI-assisted weight management 1

This approach represents a shift from the traditional scale-manufacturer model toward a consumer health ecosystem. In this model, the physical scale acts as an entry point into a broader system involving data collection, dietary tracking, and personalised weight-management recommendations.

Smart Body-Fat Scales

The primary product category for LEFU is its range of smart body-fat scales. These devices combine standard weight measurement with body-composition analysis. The catalogue includes various generations and configurations, featuring Bluetooth and Wi-Fi connectivity, different display technologies, and multiple electrode setups. The company also offers eight-electrode smart body-fat scales, which represent a higher-end configuration within its portfolio. 1

Smart Weight Scales

LEFU produces connected digital scales focused primarily on body weight. These serve as lower-complexity entry points into the company’s smart-health ecosystem.

Calorie and Food Scales

A significant component of the portfolio is the “LEFU Calorie Series,” which includes the Smart Kitchen Scale Pro and multifunctional calorie calculators. These products link food weighing with calorie-management concepts, supporting the workflow of measuring the body, measuring food intake, and managing calories. 1

LEFU’s hardware is supported by smartphone applications and digital services. The Unique Health application, used with LEFU-compatible smart scales, synchronises data such as weight, BMI, and body-fat percentage with Apple’s Health system. The App Store listing for the application explicitly notes that the Bluetooth body-fat scales are not medical devices. 1

Consequently, LEFU occupies a market space between consumer electronics and wellness, distinguishing its products from medical diagnostic equipment.

The technology stack relies on connected weighing and body-composition measurement capabilities. Depending on the specific model, features may include:

• Bluetooth connectivity
• Wi-Fi connectivity
• Combined Bluetooth and Wi-Fi
• LCD, LED, or colour displays
• Electrode-based body-composition measurement
• ITO-coated measurement surfaces
• Multi-electrode configurations 1

The overarching strategy involves converting physical measurements into digital health data accessible via mobile applications.

Manufacturing is central to LEFU’s identity. The company describes itself as a source manufacturer and claims to supply or produce products for major international brands. It reports an annual production capacity of over 15 million units and sales across more than 80 countries. 1

This dual role means LEFU operates as both:

1. A consumer-facing brand selling smart health products under the LEFU name.
2. An OEM/ODM manufacturing company producing weighing and body-composition hardware for other brands.

This second aspect aligns with common practices in the global smart-scale industry, where many branded products are manufactured through OEM relationships.

Recently, LEFU has promoted itself as an “AI weight management expert.” Corporate messaging highlights the integration of smart hardware measurements with dietary information and professional weight-management services. The goal is to move beyond simple metrics like “how much do I weigh?” toward comprehensive understanding and management of weight through AI-assisted tools. 1

LEFU states that its products are sold in more than 80 countries, including markets in Europe, the United States, and other overseas regions. The company emphasises its experience in manufacturing for major international brands, indicating that its global presence extends beyond its own branded products to include OEM/ODM exports. 1

LEFU operates at the intersection of consumer electronics, IoT devices, health technology, fitness tech, digital wellness, and nutrition technology. Its closest product category is the smart body-composition scale. Conceptually, it competes with brands such as Withings, Eufy, Xiaomi/Mi, and Garmin, although LEFU places substantial emphasis on integrated weight-management services and manufacturing capabilities. 1

Based on publicly available information, key strengths attributed to LEFU include:

• Extensive experience in weighing technology
• Large-scale manufacturing capability
• Broad smart-scale product portfolio
• Strong OEM/ODM capabilities
• International distribution network
• Integration of hardware and software ecosystems
• Expansion into nutrition and calorie management
• Focus on AI-assisted weight management 1

It is necessary to distinguish LEFU (the smart-scale brand) from other unrelated businesses using similar names. For example, LEFU Textile is an Istanbul-based apparel manufacturer 3, and Qingdao Lefu Housewares is a separate Chinese manufacturer specialising in glassware 4. References to “LEFU” in the context of health technology and smart scales specifically denote Shenzhen Lefu Weighing Apparatus Co., Ltd.
