Personally I am not having all the problems I see in other reviews. When I clicked +40 (seconds) I was offered an upgrade, I upgraded and since have had no ads or problems. Sound effects make the song sound like bird voice, cat voice, et al, but is mostly about speed. Bird = fast, Elephant = very slow.
It is quick and easy. I can choose any song in my iTunes and can start/finish anywhere in the song. I love it. Easiest ringtone maker yet.
A suggestion : allow the marker to stop and star anywhere within the 40 sec. Then I can be very specific with beg/end and wont have to re-listen to the beginning each time.
So I love it.
Thank you, developers!
