AudioPlayer+ -- Free

AudioPlayer+ is an easy to use app for your iPhone or iPod Touch that you can use to play the music, podcasts, and audiobooks in your iTunes media library
Features:
+Includes two player interface modes to choose from depending on your needs (button and gesture).
+Button interface mode is easy to use with large buttons. No more accidentally starting the track over again when you try to hit play or pause.
+Gesture interface mode includes all of the same functionality as button interface plus the ability to change brightness (13 total gestures). Gesture interface is great to use if you are in a car and want to keep your eyes on the road.
+Bookmark any position in any audio file in your library. No more losing the position of the audiobook or podcast you are listening to.
+Ability to disable the idle/autolock timer option when using the gesture interface (available in settings view).
+Simple to navigate between your music, podcasts, audiobooks, and the player views.
+Programmable two-mode skip forward and backward buttons.
+Variable speed scrubbing control of the track time slider which works the same as it does in the Music app.
+Search for items in your media library.
+Ability to sort all of your podcast episodes by date.
+Works with Bluetooth.

My philosophy for this app was to start by doing a handful of things very well and then start to build more features once the basics are rock solid. I use this app every day as my audio player and I am committed to adding more useful features and fixing any issues that may come up.

Thanks for your interest and send me feedback if you have any questions or comments.
