The Aria Smart Scale is built by Fitbit to augment its line of fitness trackers. Aria is a fitting name for this product as it complements the rest of the Fitbit line, but stands apart in function and form. While the Aria scale is very different from Fitbit’s main line of products, their engineers have done an excellent job on design and engineering. From the design for assembly (DFA) to the component selection, the Aria’s hardware tells a story of a team that did product development right. Looking inside, I see a no-nonsense design that takes advantage of off-the-shelf components and does not compromise on aesthetics or cost.
