A cipher is read as a secret that can only be unlocked with the right key. It points to puzzles in waking life, or to feelings kept in a private code.

My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
