Weight Watchers Mobile app is designed by Weight Watchers International, Inc to help people with weight problems lead a healthy and self-disciplined life. Instead of counting calories, it adopts an easy-to use system - tracking points. Every food is assigned a certain points value, and the goal is to stay within your points quota for the day.
Weight Watchers Mobile is available and free to download both on Android and iOS platforms. To get the most out of this app, you'd better get a subscription to Weight Watchers Online. It charges $17.95 per month (plus a $29.95 start-up fee), which is not a cheap price.
