Sincerely, the company behind Postagram, PopBooth and Dotti, has now created Ink Cards, an app to create personalized photo cards on your phone or iPad and then send in the mail. The iOS version is available to download at iTunes and the Android version is available to download at Google play.
Customize and mail unique greeting cards that make drugstore cards look dreary and dull. Create birthday, holiday, and greeting cards from your iPhone or iPad without a trip to the store (or even a stamp!). Add your photos, special notes, and other personal touches with just a few clicks.
