Thank you for so many replies and I think most of the members here not in opinion to have a new app.
I have not checked the topic on search engine before post. sorry for that. It just came in my mind that many new users have been joined so lets start a discussion whether such feature is required or not.
I respectfully agree with the thought that you can always use browser to access the forum. But if this is the only oint then I think there was no need of having Quora application because we can also read quora on browser. Similarly, news website also should have not been developed their app and,
we can also check our smartphone, we have many apps installed on phone while there are perfect website available to access that service may be news app, or a ticket booking app.
In my opinion is "Convenience" is the thing. That is why almost every website with good user base have application for user convenience.
One of the member mentioned that we should work on website forum script. That is also one appreciable thought.
