Cheeks show colour and emotion, read as warmth, health of spirit and how openly you feel. A kiss on the cheek is traditionally friendship; a slap on it, shame or a rebuke.

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.
