Used to be good till recent update

***Needs to work in background mode i.e. The track needs to work in conjunction with your own music or podcasts. Other apps allow this.****
Update August 2016:

Took back a star ancestors the app is unusable without Internet.

Update July 2016:
The user interface was quick and easy earlier. Now that a list mode has been adopted it is little disconcerting.

Earlier there were some options disguised as tracks which required you to purchase or download a new app.

New version: the English text needs some work. Seems like it has been translated using Google translate.

I have not encountered internet requirement as others have pointed out. Perhaps because I am still using the default tracks that ship with the app.

This is a prime example of "if it aint broke dont fix it".

Thankfully no ads at least.
