Fooducate is another weight loss app that is worth checking out. Although not as popular as the two above, Fooducate offers users a different approach towards weight loss: it helps users alter their eating habits and ensure long term healthy weight loss. It helps you track your food intake, and also provides you with information about the quality of the foods you are eating by giving you a quality rating on each food. You can also create healthy grocery lists with this app. Again, this app is completely free.
