18-Metric Smart Body Scale $19 Shipped

A basic bathroom scale tells you one number. This iMounTEK Smart Scale tells you 18, tracking weight, BMI, body fat, muscle mass, bone mass, and more, then syncing it all to the mobile app, which also works with Apple Health and Fitbit. It reads in 0.22-pound increments, handles up to 397 pounds, and the batteries last about six months. Use code BD342AT to drop it to $18.99 with free shipping at Daily Steals. The same scale runs $27 at Walmart, and we spotted it for as much as $45 elsewhere.
