Now, this is something weird.. there are multiple reiterations of the same calculator from the same developer: the 570, the 580, the 580 Pro, the "Pro", and the "All in one".. but nothing indicates *in what* these versions are really different, except that the Pro's have no ads. Oddly enough, the 570 seems to be the most downloaded and reviewed one, or maybe it makes sense because it's an older version? In any case, it keeps getting updated fairly often, just like the other three, or four..

It has better performance compared to the other scientific calculator apps I've tried. It does't lag even in my ancient Samsung Duos. And this app keeps its functions separated, which makes it even more effective. It does't hiding those options (like conversation options) behind buttons like a physical calculator. Great work!
