Teaching APPZ - a directory of educational apps that can be used in the classroom and/or by Family Learning Practitioners.
Currently there are over 100 apps on the site, all of which are organised by subject, age range and device so you can easily find apps that can be used in teaching and learning (Those engaged in Initial Teacher Training should take a look!).
Currently supported devices include iPod Touch, iPhone, iPad and Android, as well as a number of useful web apps.
A useful guide to the quality education apps that are available and growing.
