NO annoying pop-up ads!

Good free calculator with low price to upgrade to better themes, but the free themes are decent. Another good thing about this one and the very reason I uninstalled my old “free” calculator is this one doesn’t have pop-up ads. Only an ad bar at the bottom of the calculator screen. My old calculator suddenly started popping up ads right in the middle of my calculations, so it had to go. I don’t know why my iPad Air didn’t come with a calculator. Shame on Apple. I give Apple a negative rating for that for sure!

It’s good

I like how it is a calculator. But I just wish it didn’t erase the whole number when you make a mistake. Just do one Number by one number. I would also like it to have exponents. I’m not sure if there are exponents on the buttons, because I’m just a fifth grader so I’m not sure but because of that I think you should add some thing that you can recognize as an exponent. Because not all people know these math symbols. I would also like an option where we can do remainders instead of 1 million numbers behind the decimal. I also want to be able to controlThe theme, but I’m sure there’s a button for that but it just didn’t work. I’m tired of seeing black and orange colors whenever I open a Calculator . That’s it. It’s a nice calculator. It’s all the jobs done that I need. But sometimes with the exponent in the remainders it’s difficult.

Developer Response ,

- Erase a single digit can be done by swipe left or right across digit screen.
- Exponents is a part of scientific calculator, which can be switch by rotate to landscape orientation or manually switch by tap A button in the top left area.
- Themes changing is a part of full version, which includes ads removal, unlock all themes, and do calculation in widget.
