AirCalc it is a floating calculator. Whatever we do, it always stays in the front row. And it does not matter if we are browsing and change the page, enter the agenda, start a game, or open a document. We will always have the calculator in the same place. This is ideal for adding elements from different pages or places on your smartphone without losing your account.
AirCalc occupies a small portion of the screen. If we press the keys of the calculator we will interact with it, while if we click on another part of the screen, we will use it as we would in normal situations.
Something that I really like is that we can resize the calculator, to give it the optimal size in which it does not bother us too much, but is still useful for us. In addition, if at a certain moment we do not want to have it occupying so much space, we can click twice on the upper bar of this, and it will hide until only the bar itself remains. On the other hand, we have the gray minimize button, which hides it completely and allows us to open it later from the notification bar.
But it is not the only thing, we can adjust the opacity of the buttons themselves AirCalc, to have a greater or lesser visibility of what is behind it. We even have the option of having several calculators AirCalc open on screen. By the way, if we slide to the right, we will find advanced calculation functions, such as sine, cosine, tangent, logarithms, both percentage, and special numbers such as pi.
AirCalc is a totally free application that is available in Google play and that allows us to really work on Android in multitasking mode. Ideal for tablets, especially, although compatible with smartphones.
