Parents, teachers, and students with special needs all love the Time Timer because it shows the answer to that age-old question, "how much longer?" We think it would be perfect for answering questions about Santa's arrival or lighting the candles, opening presents, eating dessert and going to grandma's house. We would also use it to provide more practical time frames for things like brushing teeth and bedtime.
The Time Timer App has all of the features and advantages of the physical timer with the boon of portability. It can be viewed horizontally or vertically and users can opt for a digital time overlay display. Devices will sound a chime when timing is complete and iPhone users can also select a vibrate option. $3.99* from iTunes.
