We were trying to use that online stuff to download mp3 from videos, but it was just too much of a pain. Then there's this app called TubeMate. It seems to work ok but asks too many permissions. Sure, there are only three, but does it really need phone call access and location? I tried denying those two, only to switch them on because it didn't work without them. Right now it's installed, with those two permissions not allowed. Who on here has any experience with TubeMate and/or could offer advice?
