Hi. RealPostcard is a one of a kind app based on advanced steganography (the art of data hiding) technology - ONE PHOTO, TWO SIDES. RealPostcrad on app store A RealPostcard is a standard JPG photo which you can Send via mail or save to your photo library. The postcard will then function as a regular photo in your photo libray, BUT if you open the photo with RealPostcard application you will discover that the photo contains two sides which you can flip using your fingers. JUST LIKE A REAL POSTCARD Create your postcards by choosing one of your photos for the photo side, than flip the post card to edit the text side. When a person receives a RealPostcard in his mail, he will see a standard JPG photo which he can save to his photo library. If he'll open the photo using RealPostcard app, he will be able to see the photo as a real post card by using his fingers to flip the postcard from one side to another. We strongly recommend on using any of the magnificent photo design iPhone apps in order to create or design your photos, later to be used as the photo side of the RealPostcard. RealPostcard is a general post card generator which can take any of your photos. Coming soon : - Facebook integration. - Twitter integration. Any feedback appreciated. Thanks.
