The Visual Timer with Planning Board is a versatile, easy-to-use tool designed to support focus, time management, and daily organization. Its clear countdown display, combined with a dry erase planning board, helps users visualize tasks, stay on schedule, and reduce overwhelm. It’s an excellent resource for individuals with ADHD, autism, executive functioning challenges, or anyone who benefits from visual structure and routine. Want to try it out for yourself?
