The three-day finale to summer is right around the corner, and our thoughts are already tracking toward firing up the grill and knocking back a couple cold ones. But before you fall completely into that long-weekend languor, check out the cool enterprise mobile apps we’re recommending that will make your return to work a bit easier to bear.

  • Brewster – We like this cool means of integrating and organizing all your contacts, across all the diverse platforms where they hide. Facebook, Twitter, LinkedIn? They all play nice here.
  • eFileCabinet – Clean and easy means of online document management. Sales pros are liking the storage power without gobbling up space on their devices.
  • Grooveshark – Our favorite mobile music app right now. Great for new music discovery, playlist management, portability. Now, someone invent an app that prevents you from losing headphones.
  • Lumosity – Brain building games that that purport to improve memory and retention. A great airport time killer that makes you feel less guilty about goofing off.
  • RightSignature – With the days of ink-on-paper on the wane, plenty of docs still need that old-fashioned John Hancock. Nice that you just need a tablet and this app to make it happen.
  • Trello – A cool organizational app that a few of us are just starting to play with. Create lists on a virtual bulletin board, annotate assignments, loop others in for easy collaboration and resolution.
