Price and rating as shown on Amazon when we collected them. Both change.
InBody is best known for the professional body composition analysers used in gyms, and the H20N is its consumer model. The listing describes a floor scale with a 330 pound maximum capacity, a plastic body and a unit weight of 2.7 kilograms, measuring body fat and muscle mass alongside weight.
The specification is deliberately sparse compared with the app-driven scales elsewhere in this ranking: no connectivity is named in the table, and the readout accuracy is described only as within industry standards rather than as a figure. It is also the lowest rated entry here, at 3.8 stars, with the largest share of one-star ratings in the comparison, so the distribution bars are worth reading in full before buying. It carried 533 ratings at the time of collection. Everything here comes from the Amazon listing rather than our own testing.
How those 533 ratings break down
An average hides its own shape. This is the spread behind the 3.8 stars.
