The AllCast interface is simple and direct: on the left pull-out menu you can find shortcuts to your image and video gallery, to your music, and even to your Dropbox and Google Drive folders (you just need to sync your accounts for this).
Sending images, videos, and audio files to the screen is as easy as selecting that option on your Android device. And the quality is outstanding ... even if the videos do have a watermark on the lower right corner of the screen.
AllCast is a good 'cast' app that lets you send any kind of multimedia content to your TV screen.
Requires Android 4.0 or higher
