Postagram
A no-frills version of
Postcard on the Run,
Postagram allows users to create postcards by taking a photo and adding a message. The app then sends the card for you. The photo on the postcard comes with a perforated outline, so recipients can detach and frame it.
Cost: 99 cents for a postcard sent within the U.S.; $1.99 internationally.
