No, one tablet for every four or five students is sufficient, as students only need access to a tablet to test their apps: the majority of the time will be spent on the design and coding stages using MIT App Inventor. In addition, the apps built during the course can be tested using an Android emulator such as BlueStacks which allows Android apps to be run on the student’s PC. However, having access to an Android phone or tablet makes testing apps more engaging, and also allows device sensors and media capabilities to be used in more advanced apps.
