Food and cooking
This has 250,000+ recipes, and will give you grocery lists based on them, let you add your own, or import recipes from your friends. If you like (or want to like) to cook, start with Big Oven.
Food Network In the Kitchen
Food Network’s official app combines the recipe-browsing functionality of BigOven with the shows and chefs you love, allowing users to search by chef or ingredient to fit your favorite tastes.
If you’re like us (read: lazy), GrubHub will get used far more than any app that requires you to cook for yourself. It works almost anywhere and lets you order delivery or pickup from most restaurants.
Calorie Counter & Diet Tracker
For those looking to make some changes to their physique, MyFitnessPal’s Calorie Counter app is perfect. The app allows users to take pictures of barcodes to sync nutrition facts for any food product, and you can create goals to reach your desired weight.
