What is it about?
App Store Description
Have you ever needed to pick random names out of a hat? Pick your random numbers for the lottery? Out of the Hat is designed to do just that.
Create groups of names, numbers or any other collections. You can create as many different groups as you like.
For each group you can create items, names or numbers.
Choose a group to be entered into the hat. In order to pick an item either shake your iOS device or tap once on the screen. Your unique name or number will be pulled from the hat. Each time you pick a new item will be picked from the group until all items have been picked.
The hat can be reset by selecting the same group again or selecting another group.
"Teachers are finding Out of the Hat useful for fairly selecting students to answer questions."
