I have a confession to make: I don't use ringtones. Most of the time, my phone is on vibrate, and when it's not, I insist that my ringtones actually ring. However, if I were to use custom ringtones, Ringtonium is the app I'd use to set them up. This app is beautiful. In a way that few apps are. The interface is brilliantly easy to use and accessible to even the most tech illiterate users.
