Keeping track of your Weight Watchers points can be onerous, especially since the diet program just overhauled its decade-old points system. So Weight Watchers has an app that tracks your points for you: just enter your meals and the app automatically converts them into points. Want to fix a quick meal, but have only 7 points left for the day? The app lets you sort recipes by point count. There’s also an activity tracker that helps you keep up with your exercise points, and a search feature that allows you to find meetings by zip code. For users of Weight Watchers’ website, the app syncs automatically with your online account so your points stay up-to-date across platforms.
Cost: Preview is free but the full version is available only with a Weight Watchers membership
