Calculate which app use more internal space among my link2sd moved apps That's my problem:
I use, happily, link2sd and after installing a lot of apps I got my internal memory full again.

Now I'd like to delete apps but I have no clues on how internal space they use since I've moved them with link2sd...

Any apps/hints?
Use Disk Usage app. It draws nice graphical diagram with directories proportional to their size. There's a dedicated lookup option for apps too.
