If you are someone who wants to manage his daily finance in a very easy and simple way, Expense Manager by Markus Hintersteiner is the best one out there in Android PlayStore. It has a very clean and simple user interface and that is the best feature of this App.
I have loved this app since day one and did not hesitate to buy the paid version of it.
However , there isn't much for Income management here, But that is fine. I have tried a lot of other Expense management apps and all of them were so heavily built that you will get confused all the way using them on daily basis.
