Worst calculator ever!!!!

I got this app because I have an iPad, which doesnt come with the standard apple calculator, so I got this one it worked fine for a while but every once and a while it would exit out automatically. It kept happening more and more frequently, until I couldnt even use it any longer! Another reason why this is the worst calculator app is because you can only preform multiplication, division addition and subtraction. It also constantly runs adds at the bottom of the screen which you cant even turn off with airplane mode. I switched to "the calculator" which is a way better calculator with manny more applications.
