Maintaining one's diet, change, can be pretty tricky when you're on the go.  However, the newly-designed Weight Watchers official app, PointsPlus Calculator, makes it easier.  Whether you're out to dinner or picking up groceries for the week, all you need to do is enter the nutritional information into the calculator to find out how many points-per-serving an item will be.  The app will also let you log activity to see how many points you have burned by exercising.  The interface is simple and sleek.  PointsPlus is free to download, but is only available for Weight Watchers Online and eTools subscribers.  Due to the nature of the subscriptions, users are required to log into the app on a monthly basis.

Weight Watchers is just one of a plethora of companies to release "official" apps for for WP7 in recent weeks.  Microsoft likes this one so much that they listed it as one of their "must-have" apps in their Best of Marketplace.  Click on the Via link below to see the others that made the list.
