App doesn't work – QuietScrob – Last.fm Scrobbler Review

I've had this app for several months now and it just doesn't work as it should. Sometimes it scrobbles sometimes not. It misses tracks, scrobbles same track multiple times. And now all of a sudden it completely stopped scrobbling and all songs disappeared from its list.
