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!

Great dual purpose calculator!

Being able to switch between a simple basic calculator and
a scientific calculator has been great for me when I need
to make calculations on the go. The only thing that could make
this calculator better is if they added a business calculator to the mix. I would gladly pay for that.

I have been using this app because my new iPad Pro came without the calculator app! This is a great alternative app for anyone who had the same issue. It looks exactly like what apple has designed for the iPhones and iPods. Thank you!
