About RENPHO
RENPHO was founded in 2016 in California and is headquartered in Irvine. The brand launched with a single product, the Elis 1 smart body fat scale, built around an affordable take on bioelectrical-impedance body composition tracking, and has since expanded into a broader lineup of connected health and wellness devices, including massage guns, foot and body massagers, heating pads, eye massagers, and air purifiers. RENPHO states it has sold more than 10 million smart scales worldwide since launch.
The RENPHO Elis 1 Smart Scale is the product we evaluated against six competing smart scales and made one of our top picks, on the strength of the largest independently-verified Amazon review base of any scale in that comparison — over 334,000 ratings. Its Bluetooth-connected RENPHO Health app syncs natively with Apple Health, Samsung Health, Fitbit, and MyFitnessPal, and tech press outlets including TechRadar have covered the Elis 1's popularity and its unusually large five-star review count on Amazon relative to its price point.
