Split Screen App

I keep forgetting to ask, but does anyone have a reco?



I need to get something for work and even personal use. My work flow could use some improvement.



I was looking at the app store's :



Tile WIndows Lite http://ift.tt/1yWulPc



Tilw Windows http://ift.tt/1yWulPe



DIvvy http://ift.tt/1yWulPg



BetterSnap Tool http://ift.tt/1yWulPi



The latter two seem to be leading the vote getters.



Any personal accts to contribute? Thanks
