The less apps I have, the better my phone works. So I try not to download any, but I can't live without a few chat apps. Need to be able to stay in touch with my girls.
TubeMate, KissAnime apps I have, Unnofficial 7Sins app, tTorrent Pro, Mega, MX Player, VLC Player, CCleaner, CM Cleaner, ROM Toolbox Pro and quite a few more.
