A great basic calculator with memory. For my needs, this app is great. Contains features I wanted, easy to use, very easy to see. I deleted the factory calculator app's on six different devices and installed this app in their place.

Evil ads - I don't mind ads but these lie
★☆☆☆☆Ruben Neris· Jun 22, 2026
I got confused because I really thought that this calculator was a scientific calculator with more functions. This is just a basic calculator. I paid $11.99 for this simple app calculator. Now I realize that I should not have paid that much money for this app calculator. I made a big mistake purchasing this basic app calculator.

No longer calculating percentages correctly. Any time I key in a price plus percentage off, i.e. 20%, it shows me '20% is what of (cost). I need ACTUAL percent off
