There are tons of Apps in the Apple Iphone app store. You can anything from apps to count your calories to counting your weight. There are even apps to help you organize your recipes. However out of all the apps I've had try two I think really stand out to help make a foodie's life more easy.
Both of the my favorite food apps are free, so go ahead and grab them from the app store.
The first is the Yelp app. Nice little app that can search any restaurants reviews and can even locate restaurants in your area. There's even a augment reality mode that so far is more of a gimmick than something really useful.
Pros: Easy to use, lots of restaurants. Lots of reviews
Cons: Some of the reviews are a bit....well, suspect. And a consensus reviews isn't always the best review.
The second app is Epicurious. This is a recipe app that you can search for any dish. The one thing that separates this from others is the wonderful pictures some of the recipes. It's on par with some of the nicer cook books.
Pros: Easy to search for, lots of recipes. Pictures are top notch.
Cons: Requires the internet connection, and some recipes are a bit tough.
So far I think these are top apps for foodie so far. If I find others that are good and free, I'll update this post.
