Kids Calendar is an iPad app that allows children to create their own calendar. Designed for children ages 5-12 it gives them control over understanding of what their day/week will look like. For children with ODD this can be helpful in tracking their activities but also reminding them when they have an upcoming reward for acceptable behavioral choices.
WatchMinder is a programmable wristwatch that can be used to give children cues about behavioral choices. For children with ODD, this could be helpful at times when they are most likely to have negative reactions. For example, if the overwhelming choices at recess can trigger negative behaviors, then a reminder could be set on the watch just before that time to help students remember how to deal with that situation.
