I can't get the app to work either...after paying, no less. Took two days to squeeze a license code out of them (ridiculous). Now, it launches, but without control buttons, even when the iPad is connected:

I've never been so ticked off by a paid app without even using it.
I think I had to restart everything ...iPhone, Macbook to get it to work properly. and iTunes. I can't remember if I had to close iTunes and then star the app so it connected the phone there first. it took a bit of work but i managed to do a clean.
Either I am better at things now or the program isn't as good since it didn't find a whole logo of difference in clean space.
Also, oddly the iTunes said around 7gb free and Phone Clean said 5gb...but then cleaned it to about 7GB.
