Paid $15 and I am still constantly Nagged – PolyNome: Review

I understand that developers need to make money. But I paid $15 and I am continually nagged to subscribe. I just need a basic metronome application, and thought that paying the $15 would provide that, but I'm ready to uninstall and just create my own beats in Guitar Pro.
