The smartphone has replaced a lot of things. For me, one of its most notable uses is as a portable music player. Frankly, I have not even picked up my iPod Touch in... months. Yet, your smartphone needs a good app to play that music. Poweramp has been one of the big names on Android for a long time. It was my player of choice at one point. Luckily for some, this is the $0.10 app of the week (since the game has been posted already). You should all know the drill by now.
Poweramp has been the number one music player in the Play Store for four years now and there is reason for that. It features gapless playback, an amazing equalization system, crossfading, and support for most any music file format.
Purchasing the full version nets you access to updates for life and to a dedicated music player that focuses solely on providing a good sound experience. So far, this deal is good in the U.K., Australia, Italy, France, Russia, Germany, and Spain. Poweramp is well worth the 10 cents, I think.
