When selecting an app, there is not one app that is perfect for everyone. Every teacher and classroom has different needs from an app. It is recommended that you try at least three or four apps in a certain area to figure out which one best meets your needs of your classroom. I usually try 5 or 6 apps to figure out which one I want to use. Every app has something cool that other apps do not have. To see a lisiting of these apps, please see the link below.
