I thought the site is responsive but I guess it is just the landing page that is in responsive format. If they can't make the whole site responsive I agree that they need an application for mobile. This is for best user experience. Anyway, I find the site good and attractive though I think I am missing something, are there really only four market pair in this exchange?
You're not missing anything as there are only 4 market pairs at the moment.
Those are the coins of the dev.
And I can't see also the contact link for this exchange.
The dev should include that in his homepage as it is one of the important info for the site.
