Smart Calculator (v1.1) manual

Hello. I'm Android Boy, the chief developer of Smart Tools co.,

The pre-loaded calculator app on Galaxy phones is so great that I did not need to create our own. However, some phones, such as Motorola and Infinix, do not have a pre-loaded calculator, and I'm well aware of the limitations of the Galaxy calculator.

We adopted the same design as our existing unit converter. It makes this app intuitive and simple with a familiar interface. 

First, we launched this app with two calculator types (Basic, Scientific). Two more tabs are in progress. (money, misc.)
