Time Timer has proven for 25 years to be a globally recognized time management resource for kids and adults. The learning timer is designed to show the passage of time using the signature red disk. As time elapses, the red disk disappears clockwise in a clear, visual way making daily routines stress-free and enjoyable at home, school and work. The optional alert (on/off) on the back of the timer controls the sound at the end of the timing cycle. Turn the center knob on the front of the visual timer counterclockwise until you reach your chosen time interval (up to 60 minutes). The Time Timer MOD Home Edition is the ideal 60-minute visual timer for all abilities and ages, including kids and adults with autism or ADHD. Personalize your desk timer, homework timer, kitchen timer, school timer or work timer.
