Sap is the lifeblood of a tree, so it is read as vitality, energy and what flows beneath the surface. Rising sap is linked to renewal and spring; dripping sap to feelings spilling over.

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.
