Two of my favorite apps are Pocket (for articles storing) and B1 Free Archiver as I usually download a lot of media (beats ZArchiver in everything). You should try them up if you haven't yet.
Car home ultra I love.
Acar for car expenses rocks as well.
Tasker. It's much cheaper then in the past and don't need root for some things. Nova Launcher
HD or beautiful widgets
Business calendar
Keyring
