A Better Calculator

The Calculator app on your iPhone isn’t bad, but it definitely could be better. Right now, it’s got a lot of limitations that Android users don’t have to struggle with.
For instance, the calculator on Android keeps a brief history of your most recent calculations. If you only use the Calculator app for a couple of calculations every now and then, you probably don’t even care about this, but if you want to do things more complicated, like your taxes, you’d be better off with an Android phone.
Besides the history, most Android apps also come with more features right from the get-go. You can get a more professional calculator on your iPhone by placing your iPhone in landscape mode, but it would definitely be better to use pi or calculate the square root of a number without having to tilt your iPhone.
