Recipe gathering app
I own an iPhone and I have various foodie apps on it. The one app I wish someone would make is one where I can collect all the recipes I have on all the Foodie sites I save recipes at. It would be nice to open an app, go to a website like Epicurious and access my saved recipes and then sync it to the app so that I carry a rolodex of all my recipes.
Evernote has a iphone version. I use the Mac version on my laptop and it's great. They do have it for ipad as well, and I believe it will sync to a computer and even backup an online version of your collection. It isn't just for recipes and I use it to keep track of ideas for other things as well. I have tags for the sites recipes came from. You just open the website, click the elephant (added to the browser window) and it's clipped to your files.
