Small Download, no Ads

I just wanted a calculator that honestly should have already been sent with an iPad (considering all the bloatware I received but never asked for). This calculator works, it has no adds, and is very small in size. I think 8mb, but don’t quote me.

Thank you for taking the time to build this for people, you saved me some time and money. I figured it was the least I could do to rate it. Keep up the good work.

Best calculator app for iPad

Was a bit shocked to realize there wasn’t a simple calculator app already preloaded and didn’t feel like I should buy an app either. This calculator is excellent! Simple, yet also has scientific calculator capabilities. You can have answers in decimals or fractions and no stupid ads... there should be a preloaded calculator on the iPad and this app should be that calculator. Hats off to the developer! Thanks for an awesomely designed app.

Perfect essential

Honestly i was dumbfounded when i saw the iPad had no calculator. All these other apps have ads, but this one fits the bill. It gets the job done, no annoying pop-up ads, and small size. Exactly what i need, but i’d like the swipe right to backspace function like in the original apple calculator. Maybe next update add into it? Oh well, Beggars can’t be choosers, thank you nonetheless!!
