The Best Weight Loss Apps Worth the Download

Food-Tracking Weight-Loss Apps

Most weight-loss apps allow you to track your food and make smarter nutrition choices — and a few of those programs are below. That said, the best weight-loss apps also let you track your workouts and hydration as well as sync with wearable devices too.

Noom is a head-to-tail weight-loss app that helps you set goals and track your progress.
