Good basic features... But changes my lock screen image when purchased is insulting

As an entrepreneur I applaud anyone who can get a paid app off the ground, but... When you pay for an app you expect to be excluded from any free app trickery, like sending me notifications I dont want, or delivering me ads, or changing my settings. I bought this app happily for its 1 feature, which it does well, except for the fact that you cant fast forward through a song to actually experience the apps only feature, in my case I had to wait 3:55sec for my song to finish... Back to my point. Before this app install I had selected, scaled, and set a beautiful picture of my daughter for my lock screen... After the install and use, this app replaced my lock screen image with a poorly designed, not optimized for retina display, ghastly logo image... NOT PROFESSIONAL!
