Tech companies are pushing ever further into health and fitness tracking for a few reasons, not the least to sell you subscription services. Above all, though, is the obvious commercial appeal of improving your body. Whereas buying a new Android phone might only make TikTok or Google Maps faster, a good fitness tracker (combined with a science-based plan) could help prevent a heart attack or push your bench press to 200 pounds.

An affordable and increasingly common form of fitness tracker is the smart scale. I recently had the opportunity to test two models — the high-end Withings Advanced Body Composition (Body Comp) Wi-Fi Scale, and the more affordable Wyze Scale — to see how useful one can be in boosting your health.
