Marrow is a companion for the hours between meetings. Not a tracker that punishes a slip, not a program that graduates you, and not a replacement for the rooms.
AA, NA, and SMART matter more than Marrow does. It points you toward real meetings rather than holding you here. How it works →

Only ever rises. A hard night does not take it away.
This stretch. Starts again when it needs to.
Breath is optional. After three rated runs, Marrow remembers which ones work for you.
