Are creating and linking to Facebook and Twitter profiles worthwhile.

I have an app that gets a fair amount of play already (2.5-3k daily installs), all through Google Play store search. I’m not really up on social media much, I’ve never made profiles on “the” Facebook or Twitter for my app. Is this something that has any value, can it increase my downloads at all if I make nice pages for it, and link to them in my app? I’m not talking about paid advertising there, just pages for it.

yeah its very necessary if you need to improve your sales
