When you are making a call to someone, you may hear sound, that you don't like: annoying music, ads, etc..
This app makes you hear Ringtone, that YOU LIKE!
Man, you really need to post video.
It's not as easy as cut ringtone, but record video from phone/tablet and cut it you can easily with free tools.
No-one reeds those descriptions... believe me, I know....
I guess app author have been forgotten his phone not once )))
Train your dog, not memorize numbers!
