Calculator & Math Solver

Fun fact: Apple released the first iPad in 2010. Another fun fact: in the 13 years since then, Apple hasn’t bothered to launch a calculator app for it. However, the good news is that you don’t need Apple to give you a calculator; there are already a bunch of awesome calculator apps on the App Store.
Enter Calculator & Math Solver. This app feels like what an Apple calculator app should be. You can do basic and scientific mathematical calculations and even check past calculations in a flash — something you can’t do in Apple’s Calculator app on the iPhone.
The app is free to use, but you’ll need to get a premium membership if you want to use all of its features and remove the ads. Fortunately, the free version offers more than enough features for most of us.
