5 Highest Reviewed Smart Scales for Weight Tracking

Modern technology has provided smart scales that can connect wirelessly to the internet, or interact with computers and mobile devices. Body mass data can be sent instantly to apps that help users track the progress of their weight loss. Smart scales connect wirelessly (via Bluetooth or Wi-Fi) to your smartphone, tablet or computer.

But they can do more than just record weight; many scales today utilize BIA (bio-electrical analysis) to determine different people using the scale and estimate metrics of body composition such as fat and lean muscle percentages. Because this requires a strong electrical impulse, a smart scale may not be a good choice for small children, pregnant women, or those with pacemakers or similar medical devices.

For most people a smart scale is a great way to support any diet or exercise regimen, especially for someone just getting started. Losing weight takes developing and sticking to good habits, and a daily check on a smart scale can be a critical part of that. The convenience of being able to monitor progress on a smartphone makes it more fun and rewarding.

For those serious about weight loss, here are five top picks for your next quality smart scale.
