hello there, 
I created a website in joomla then I bought the expansion of mobile joomla which I then installed on my site so that it displays correctly on mobile phones but I can not seem to create exactly mobile application on my site that will be on store or on Google app Store and can be downloaded for free by users. 
Please help me to create a mobile app for my site to be downloaded from google store and app store. 
Tell me what I should do and give me all the information possible 
best regards
