ONE STAR

This app BLEW OUT
My speakers on my phone

Porn Ads

Porn advertisements. Another app that has turned the App Store into a trash dump. If you are going to make a free app, make it free, otherwise just charge me a couple bucks. I selected this app because it had a simple feature set and a nice display layout. The Porn advertisements ruined it. Delete!

I love it !

:)
