Here are the best smart and dumb scales. I have this iHealth Nexus Smart Scale ($35) and love it so much I bought another one for my boyfriend. Generally, if you're using a specific product or suite of products, I think you should stay in the same family as much as you can. The Shapa scale ($120) is an innovative smart scale that shows you colors, not numbers, so you don't get too caught up monitoring your exact weight. Teal means you're starting to lose weight, green means you're maintaining it, light gray means you're starting to gain, and dark gray means you are gaining weight.
