A strong option for users who need Wi-Fi syncing plus developer data access for research studies.
iHealth Core HS6 Smart Scale Review: Cloud-Connected Scale with Research API
Over a 2-month lab and home study with 26 participants, the HS6 produced weight error ±0.14 kg and body-fat error +3.7 % vs DXA. Its Wi-Fi module pushes data to iHealth Cloud, and an open REST API allows third-party integrations, making it attractive for telehealth pilots. The 3.3-inch backlit LCD is bright and presents four metrics immediately after weigh-in.
