I’m assuming it works well but...

I keep getting “Error 5”, and I’m not sure what that means.

Does not seem to work on iPhone 4S

I was excited to download this app to my iPhone 4S because the competing apps require iOS 10.0 which I can upgrade to.

While the app is compatible with iOS 9.3.6 and it installs and opens fine, the bottom row and a half of buttons are cut off and there is no way to scroll down or zoom out which make the app completely useless (can't type zero or decimal point, etc.)

I would love it if this small bug were fixed! (As long as the new version still worked on iOS 9.3.6)

Best BA II app I can find on the store.
Full functional.
Thank you for the development!
PS; for those don’t know how to use this calculator it’s not the developer’s fault so don’t blame but learn how to use it first.
