Classroom and focus tool
ADHD Visual Timer
A customizable timing and organization tool centered on one task at a time. Add an optional task label, choose from editable focus presets, include an optional preparation period and break, and switch to a distraction-reduced display mode. Pause, resume, reset, or add time as needed. This tool does not diagnose or treat ADHD and does not guarantee improved focus. It is a flexible timer you can tailor to your own routine.
