Constant ads, asking for Twitter privlages privileges

This app keeps showing ads, it also states that it works for Spotify when I it doesnt, I have to purchase the premium version. iOS informed me that Youtify wanted access my Twitter account, & of course I denied. Why would this app want my Twitter, to spam my followers? And to finish off this app constantly crashes when I want to play a song.

To be honest I dont trust this app at all.
