The best weight loss apps for iOS and Android

Unhealthy sedentary lifestyles, underlying physical conditions, overeating, age, and eating the wrong foods are the most common reasons for being overweight, and many smartphone apps do a brisk business in helping people trim off excess pounds or maintain the weight they’re already at. Apps can be enormously helpful in moderating eating habits to help people lose weight, but you want to pick the right app for optimal results — and there are many options. Weight loss apps often offer personalized coaching, compatibility with various fitness trackers and smart scales, and help with deciphering food labels and bar codes.

Some apps also employ tracking tools to monitor your weight, food intake, and exercise habits. Others provide guidance for grocery shopping or eating out. Many seek to boost motivation by featuring community support, point systems, and documentation tools. So whether you want to lose weight for health reasons or simply because you want to, here are some of the best weight-loss specialty apps available for smartphones.



Noom is effective because it examines the psychology of overeating in a series of self-paced mini-courses designed to impart specific knowledge, tools, and skills to not only change your habits but also your attitudes toward nutrition.
