Is there an app for organizing online recipes?

I like to cook and bake, and usually to get recipes I'll just google the dish, click on a few links until I find one that looks good, and often use a few recipes and combine different aspects and add my own ingredients or change amounts.

Ideally this app would allow me to bookmark these recipes from various different websites, and add my own notes/measurements/ingredients. Nice bonuses while I'm app dreaming would be a calorie/nutrition calculator, measurement conversions, and the ability to make my own categories with headings to organize the recipes. Also would be nice if its an Ipad app but iPhone will do.

I use pintrest for this. Create a board for recipes and pin all of them on the board. Easy.

I use Evernote which is free. There are iPad and iPhone versions which sync to your online account and is handy for quick reference on the go. When I'm doing online research and I find a recipe I like, I use the Evernote Webclipper plugin to grab the recipe and file it. I can add keywords like "grill" or "noodles" and the clips retain the original web format. There's also an iOS app called Evernote Food which feels more like a food diary than an organizer so I just stick with the classic Evernote app. Sorry that it doesn't do conversions or calorie counting.

Pinterest is OK but it doesn't let me add notes or choose what I want to copy and file. It's more of a social platform for sharing stuff with friends.
