User texts any intentional movement completed each day — a walk, a workout, a bike ride, ten minutes of stretching. Poke logs the entry, updates the current streak, and returns a plain English confirmation with the streak number. When milestones hit — 7 days, 30 days, 100 days — Poke sends a plain English acknowledgment. The movement habit that has started and stopped a hundred times finally has something counting every day that matters.
