Why it's cool: Say you wrote a grocery list, but left it at home in your rush on the way to work. Or perhaps your husband is already out, but doesn't know which ingredients you're lacking to make dinner. With this app, both these scenarios are solved. Grocery Gadget Shopping List allows you to write a list on the Web browser and automatically sync up with your iPhone, so there's less chance of accidentally leaving your list on the coffee table. Similarly, if you add a list on your iPhone, it automatically shows up on your husband's iPhone, too (provided he also has the app). Bonus: This is one more way he can never "forget" to pick up tampons for you at the store.

VegOut

Why it's cool: Whether you're vegan, vegetarian, or are simply seeking a veggie-friendly restaurant, VegOut will find a suitable eatery in your desired location, sorted by distance. Plus, since the app is powered by HappyCow.net, each restaurant already has consumer-reviewed star-ratings, so you can tell whether the place's food was a hit with fellow diners.

Locavore

Why it's cool: Raspberries, mangoes, and kale, oh my! To find out what produce is in season, take to this iPhone app. Locavore automatically detects the state you're in and lists the foods that are at their peak freshness. Plus, it maps out the nearest farmers' markets according to your location. Unfortunately, there's no telling whether these markets will actually have your desired seasonal pick available, but it's still a step in the right direction.

Nutrition Menu - Calorie Counter

Why it's cool: This is the mother of all iPhone calorie counters. With more than 78, 000 foods to choose from (including popular restaurant picks), you'll know exactly how many calories you're eating (not to mention fat, carbs, protein, cholesterol, sodium, sugar, and fiber), which makes it easy to keep track of your food intake, even if you're following specific dietary plans like Weight Watchers or low-carb.

Good Food Near You

Why it's cool: On-the-go with only fast food joints nearby? Greasy, mass-produced food isn't your only option anymore. Type your location into this app and it'll list healthy choices from nearby eateries. Whether you're traveling or just nursing an unexpected hunger pang while out and about, Good Food Near You helps you make an informed decision before grabbing the nearest burger.

Food Additives

Why it's cool: If you've ever perused an ingredient list on a particular packaged food and wondered what acetic acid, ethyl maltol, or sodium nitrate really is, this app is for you. Not only does it list over 450 additives (which you can sort by name, number, diet type, and more), but it also lets you know potential side effects, maximum daily intake, and dietary restrictions. So hardcore vegetarians, for instance, can rejoice — now they'll know if an ingredient is animal-based. Then again, not everybody will be happy to know exactly what that their favorite cookie or ice cream indulgence contains.
