I found a Weight Watcher app to use that I really like and want to share it for those that also do it "unofficially".
Value Diary Plus Wt Watcher (android) or Ultimate Food Diary Plus (iPhone) - you'll recognize it with the red heart:
It is an app that costs and I think I paid $2.99 for it. Just the one time fee. I noticed at iTunes the app is $2.99 but also offers some subscription services, I don't see that with the android version.
Anyway, this one has a lot of bells & whistles and once you learn your way around is just as good if not better than the Official Weight Watchers one.
They also have a website: Ultimate Food Value Dairy
Check it out!!
