Android App for SocialEngine/BB Press/phpBB

I need a Social Engine or BB Press or phpBB android app for my discussion forum site. Any of the above mentioned script. I wish a app which users can download and install from Google playstore and post topics, comments, pictures, tags etc. and should get notifications when activity happens on their respective profiles. Yes, the budget is a constraint initially but I will get the features constantly upgrading for the app so there is definitely room for upgrading costs in near future. Only glitch free app is expected, so your work experience and previously deployed projects or work profile is requested.
