A sensory timer is a visual time management tool designed to engage the senses while showing the passage of time. Unlike traditional timers, sensory timers often use colorful liquids, bubbles, or gel that flow slowly from top to bottom when flipped. This slow, predictable motion provides visual and sensory input that can help children—especially those with ADHD, autism, or sensory processing challenges—stay calm, focused, and better understand time limits. Sensory timers are often used during transitions, calming routines, or quiet time to promote relaxation and emotional regulation.
