About Pictograph - Steganography
Pictograph is the best steganographic app available for iOS. Send messages and imageswithout anyone knowing.
Steganography is the practice of hiding messages in plain sight. Pictograph works by changing the least significant bits in each pixel in a specific way so that a message can be hidden. Because Pictograph only changes the least significant bits in a pixel, the change is imperceptible to human eyes.
AES-256 encryption is used in Pictograph when encryption is enabled. This encryption is incredibly hard to break, so rest assured your message will be safe if you choose to encrypt it.

You can now hide images within other images! So now you can send pictures to your friends without anyone knowing about the content that you're sending. Keep in mind that hiding an image takes about 30 seconds and showing one takes about 15 seconds. Enjoy!

When you load the app for the first time, you will now be able to see everything on the screen. Not being able to see everything doesn't make for a great first time experience does it?

Removed limit on the number of characters you can hide in a message! Well, it's still limited by the size of the image, but for a picture your phone takes, you can hide a good 3/4 of a million characters.
