I have charged me the pro version on my Samsung phone S3 Mini. The app runs so far. But the most important reason for me was the transmission of the songs on my airplay receiver. Here I find no setting in the program. Therefore, I could have saved with the paid version. According Audials it is to go with the 5 version, info on the net. From my PC with Audials Light or ONE, it works flawlessly. Account exists. Therefore only 2 stars.
