PocketPlay is an audio player for your pocket.
The trial version is limited to 14 days. You can upgrade to the full version by buying a license.
It comes with only three big, friendly buttons while playing. "Down" will go to next track, while "up" will switch to the previous one.
While songs are playing, only the most essential buttons are visible so that you can not press a wrong button accidentally. Also a notification icon is visible so that you can quickly switch back to PocketPlay if you work with other applications.
A Playlist Editor and Trackbrowser are included and accessible when playback is paused. A Default Playlist with all files in it will be auto-generated.
