I personally feel that for teaching preschool children human interaction is the best method unless there is scarcity of human resource.

May be its useful, but what about its side effect (mobile)?

Your lessons will very engaging I believe as preschool children are ICT savvy and they will be engaged in their lessons when mobile applications are used. You will be able to achieve your learning outcomes with ease. However , challenges are inevitable I'm sure. Close monitoring is vital. 

Dear Mr. Firrat Hasan, 

This is a very important question!

But research shows that when applications are used by children for a limited time (10-15 minutes per day) and their parents control them, this is not indicated as a negative influence on the children.

Wherever it's at all possible, I support human communication.

The use of mobile application is efficient when this is put in limited time and under parent control.

From the development point of view, I would make sure the interface fits both phones and iPads. This will give your app more scalability. Language-wise I would also make it scalable so that you can add translations along the road. Do not hard code it. Good luck!
