Splashtop Whiteboard allows teachers and students to turn their Android tablet or iPad into an interactive whiteboard. Once connected to their computer over Wi-Fi, they can watch Flash media with fully synchronized video and audio, control PC and Mac applications, then annotate lesson content from an Android tablet or iPad. Splashtop Whiteboard offers users of existing interactive whiteboards—such as Mimeo, Mobi, Promethean, Polyvision, or SMART Technologies—a way to extend their investment by accessing their tools from anywhere in the class (all four corners of the room!) without using wireless slates. This app costs anywhere from $2.99 to $9.99 and can be used with iPad iOS 4.0 & up and Android 3.1 & up.
