After trying many calcs out there, I have concluded this is the best ad-free expression-based calculator available. It doesn't try to look like a Casio calculator, and it lacks graphing, conversions, and advanced features. But, again, it's ad-free and expression-based, and that's what makes it a winner for me.
Nice and simple and no ads A nice and simple calculator with basic scientific functions that serves a wide range of everyday needs with a simple and clear interface. It shows the history continuously with decent amount of space and has no ads at all! Wonderful!
Decent calculator no fuss. I think this calculator is clear and easy to use and I am glad the user interface is kept easy to use. I notice a few improvements having used this application in previous versions.
