And recently we have released an Androind application. Search with the keyword "ielts4all" . you should be able to see the app IELTS 4 ALL . support us by donating to the app. :) all i can say is that its worth buying. just 2 bucks :) . that money will be contributed to the design team. we are looking forward to bring that to ios and windows too. so please don't forget to spread the word too :) Thank you very much.
