The best

This app is so easy and fun to use that I’ve told all my friends to use it

Easy breezy

Calculators with more features tend to become much more complicated than most people need, most of the time. This makes them difficult to use. Basic calculator is just a great tool to do the simple day-to-day math quickly like most people need most of the time.

Superb. Flawless victory. Mortal calculation. Fight!

Best alternative calculator next to Apples calculator. A few bad notes is that this calculator in particular doesn’t keep history, does not erase back a few steps. I like this one because it’s the only one calculator I have found to display NO ADS.

For this thank you so much and I’ll keep a look out for more useful calculators in the future.


THIS CALCULATOR HAS INE ADVANTAGE & THAT IS IT HAS NO ADVERTISEMENT ❗️
