Annoying repetitive solicitation !

The Calculator is good but, the multi page solicitation to upgrade every time I open the app makes me use other Calculator apps instead !

Calculator sucks balls

I am so sick and tired of the calculator app. You shouldn’t have to click through 5 pages of garbage and ads to use a iPhone calculator. 🤦🏿‍♂️

Too many pop ups

I understand that I don’t pay for this app, but it is a calculator. I hate all of the pop ups that sometimes I can’t get around. Better to just have a handy calculator.
