This is the second time calculator I've had. The other wouldn't go over a hundred easily and many times I had to leave that off and add the hundred after. This one is very simple and easily goes over a hundred. Thank you very much! It's perfect for what I use it for!

App won’t rotate

This would be perfect if the app would rotate when I rotate my ipad screen. I keep my ipad attached to a Bluetooth keyboard so it’s always rotated. The app doesn’t rotate with the screen...very annoying makes it useless to me.
