Each turn of a prayer wheel is said to send its prayers out into the world. Dreaming of one is read as steady, patient good intention and the merit of quiet repetition.

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.
