Apatite takes its name from a Greek word for deceit, because it was so often mistaken for other stones. Dream books read it as motivation and finding clarity about your true aims.

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.
