This app doesn't do any more than a regular alarm clock app on iPhone or iPad. While it should just work every day, it doesn't! It just won't play any song put in the playlist. And when trying to test the volume, there's just no sound.
Besides not functioning properly, it lacks of features that should be really common, like shuffle when playing own music, the ability to set your alarm while not connected and be able to play a shared library from your Mac or PC.
No Sony, what you just did was make the purchase of this product even more worthless than it already was when I first connected it to the power supply!
