Useful application but I cant use it

Unless you enable custom ringtones. All my friends have this app so theyll know because I use a standard custom ringtone for all calls. If you could do an update with that, Id be so grateful. I didnt realize this before I got it. Thanks.
And ps people, you change the timer, name et cetera in the iPhone settings. Just so there is no confusion.
