Ratings and reviews

It doesn't even work! You just get presented with the image of the calculator, with buttons that can be pressed but they don't do anything. On top of that, right on the calculator's display it asks you to rate the app positively and if it gets positive enough reviews, the devs *might* just make it into a working calculator. Ridiculous.

100% worthless and waste of time and data. As other reviews say, the "app" presents the face of the calculator with buttons that register touch, but do nothing more than light up. After several attempted inputs you will be presented with an add. That's all this does. Save yourself time and space on your device.

I have been using the calculator since it first came to Nigeria. It is wonderful and extremely easy to navigate through. I have recommended the calculator to so many students both in my school and beyond. There is always room for improvement so there are areas where I want the manufacturers to work on for efficient performance.
