The Valentine's Day section of the App Store includes options for the unattached. I don't know whether it's by accident or Apple's sense of humor, but it's good to know the App Store can be there if all else fails...
My comment on Valentine's Day App Store section would be that Apple's designer should review some of chosen apps coz some of them are really not-good-looking design. Yesterday I was searching for app that let me create my own Valentines e-card and I found this app called Valentine's Postcards. Man I don't know, this app has no ratings but its just what I was looking for. Really, easy-to-use UI and beautiful designed cards. I think this app should be featured in Apple's Valentines day section.
