My favorite APP on my phone is currently Flipboard. It is a fun content aggregation platform that you can populate with news and information about just about any topic in the world.
Once you personalize the content you would like compiled for you, the information can be read and accessed via a board-like scroll function that makes reviewing content very fast. It takes up very little phone space and due to the way it archives and compresses content, it is very easy on data usage. But don’t take my word for it, download it and try for yourself.
