PicSay Pro provides users with the “retro fix” that made Instagram an iPhone sensation (and made Instagram’s recent Android rollout inevitable). In addition to a vintage-style black-and-white option, there’s a way to caption the images you share. ($4)
Paper Camera can make ordinary photos look more like pastel paintings, comic books, or scratchy cartoons. ($2)
Postagram allows you to create your own postcard. Why settle for a cheesy souvenir-shop card when you’ve just taken the “perfect sunset shot”? Type in a personal message and this app will mail the card by snail mail to any U.S. address. (Free download, $1 to $2 per postcard)
Thumba Cam works with Windows Phone 7, whose “excellent out-of-the-box camera” lacks a good editing tool. This “filter-rich” editor is “the simplest to use.” ($1)
