LEFU

Most bathroom scales stop at weight and a rough BMI figure. LEFU, presented as a Kickstarter project, aims to replace that with a fuller picture: the maker says it measures 58 types of body data in just a few seconds, using an eight-electrode system rather than the foot-only contacts found on typical smart scales.

Hands and feet, not just feet

According to the maker, conventional body composition scales read current only through the soles of the feet, capturing information from part of the body. LEFU instead passes current through both hands and feet, which the maker says enables more accurate and comprehensive measurement, including segment-by-segment analysis of muscle mass and body fat percentage. The pitch is that this makes progress in training or weight management easier to follow in detail.

What it tracks

The 58 metrics are not listed in full, but the maker highlights several:

• Body fat percentage
• Skeletal muscle mass
• Visceral fat level
• Basal metabolic rate
• Body water
• Protein

App sync and voice guidance

LEFU connects to a smartphone app and, according to the maker, stores readings in the cloud. Each measurement is logged automatically, and long-term changes can be viewed as graphs. Data syncs over Bluetooth or Wi-Fi, which the maker says allows access from multiple devices. The scale also has built-in voice guidance that talks users through the measurement steps, a feature the maker positions as helpful for first-time users, older people and anyone less comfortable with technology.

The source also floats possible future integrations, such as AI-driven diet apps or analysis tools for personal trainers, but these are framed as possibilities rather than announced features.
