Shame is a great motivator, which is why Withings WiFi scales, which chart your weight and BMI via a companion app, are a powerful tool. The WS-30 is the simplest wireless scale yet, using Bluetooth to beam your stats to your smart device every time you step on the scale. The app provides a living log of your progress, making you fully aware of how much (or little) weight you’ve lost. [$120; withings.com]
