I'm quite pleasantly surprised with the free Epicurious app. I remember trying out the iPhone app and thinking it was an ad-laden monster and deleting it. The iPad version is really quite elegant so far and seems to have a huge searchable database of recipes (don't just use their categories, try searching). The recipes tend to be from published sources--this is pretty nice. (The internet is a great thing, but when you're looking for the perfect recipe sometimes you want to filter out the results that use, for example, canned soup.) You can tag favorites and build shopping lists. Nice layout/design, no crashes. Seems ideal for kitchen use with a kickstand.
I have a feeling they'll move the ads into place soon, or do something else (it seems too good to be true for now), but I'm definitely going to keep it around till then. This will be a nice adjunct to my MacGourmet app (where I keep my personal recipes, rather than looking for new ones). Hoping for an iPad update to the MacGourmet app.
ABC Player seemed to stop crashing for me after their update.
I like this thread--I am awful at drilling down in the app store (short attention span) and more than half the apps I'm using now were stuff I never would have found on my own.
