Habit Stack

Habit stacking is one of the most effective behavior design techniques: attach a new habit to an existing trigger. GoalOS's Habit Stack builder lets you create chains — coffee → meditation → journaling → run — with each habit linked by a CUE. The AI suggests optimal sequences based on your existing schedule and tracks completion rates for each chain. When you complete a full stack, you earn bonus XP. The visual chain layout makes the sequence feel like a ritual, not a task list. Over time, the AI refines your stacks based on which sequences you actually complete.
