Beats Yo! gives Windows Phone users a lot of bang for their drums
Notably, the WAV files you save can be easily transferred to a PC, as they are contained in the Music\Beats Yo folder inside your Windows phone's flash storage.
Although free to download and use, Beats Yo! offers in-app purchases in the form of additional drum-kits. Without these, users have only one drum-kit at their disposal. The app is compatible with Windows Phone 8 devices only.
