Checkup: Myself, Weight Watchers

Weight Watchers for Teens — Anyone's Child Tried It?

I'm in WW myself, and I have a 14-year-old son who needs to lose 20 pounds according to our pediatrician. My son is considering Weight Watchers. Anybody out there gone through this with a teen? WW puts so many restrictions on teens using the program (they can't use the online version/apps), that I'm not so sure about this.
