One of the hardest things about cooking is timing — not just how long it takes to prepare a meal but coordinating it perfectly so that all the dishes can be plated (and eaten) at the same time. Cooking Planit takes out the guesswork by streamlining your meal planning. Instead of providing a single recipe like most cookbooks, it provides a three-dish plan with easy-to-follow instructions (including a grocery list) for each portion of the meal. Think of it as a GPS for the kitchen. Basic, free; premium, $3 for iPhone and $5 for iPad; www.cookingplanit.com
