I fidget constantly

You click pens. You bounce your leg. You tear napkins into tiny pieces during meetings. People have asked you to "just sit still," as if that's something you can toggle off. Fidgeting isn't a distraction from focus. For many ADHD brains, it's a requirement for focus.

These tools give your hands (or feet, or whole body) something to do so the rest of your brain can concentrate on what actually matters.
