ABCipher is a simple, yet clever, implementation of Lewis Carroll's Alphabet-Cipher.
Slide the (blue) dots up and down to create your secret message, select a Cipher Key, and tap ENCIPHER. The columns of letters will align themselves to spell-out the Cipher Key along the top; where the (now-red) dots lie indicate the encoded characters. Tap DECIPHER to reverse the process.
• You can enter a custom cipher key instead of simply choosing a Carrollian character.
• Support for all iPad screens
Ratings and Reviews
I searched for a Ben Franklin cipher tool to work on a project. I bought this and found that you have to utilize the app's cipher key rather than your own, rendering this app worthless in my eyes. As is, I don't recommend this to anyone.
With Family Sharing set up, up to six family members can use this app.
