So the fuss here is all about Ringy Tuner the app that lets you choose a number of ringtones, actually not only number of songs but also number of lists to choose according to the situation. For the Demo the developer also included a Video with it to show how to use the app.
As you can see in the video the app allows you to select ringtones from your library to add to the lists created by you as per your requirement to use in the different scenario or locations. As per lists you can add songs to libraries based on a genre in a particular list.
The app certainly stands out from the crowd as it features total randomness while playing a particular ringtone. Though that randomness can also turn into a mess if a wrong ringtone plays at the wrong time so all you need to do is select them accordingly to stay away from any problem.
Hope you people will love it & will give it a try, do share your views about the app in the comments.
