Did you hear that Weight Watchers recently released a barcode scanner? The mobile app allows Weight Watcher subscribers to use their phone's camera to scan the barcode (or enter the barcode number) on popular food labels. If the product is in their database, you will find an informational screen on the product like the image below. Then, you have the option to track the item. If you don't wish to track the item, the information is saved in your database for later.
Keep in mind, the app is still new so the database is still growing. I've noticed that the more popular diet foods are in the system. This morning, each of my breakfast items scanned in, making tracking so easy (and fun!). I scanned each item, then clicked "Track this item." It was AWESOME! As the Weight Watchers database continues to grow, this is going to make grocery shopping a breeze. No more sitting in the aisle calculating which cookies have lower points.
