100% Positive Feedback

I have bought an apple device recently. I was wondering why there is loads of default apps that are very helpful but there is no calculator. So, I downloaded this app. Amazing, probably even better then if Apple itself made a calculator specifically for mobile devices. There is so many features, and it is very helpful. Would recommend to everyone. Sincerely I would give this app a 5 star rating because it is absolutely amazing. As I said, the amount of features are incredible and you could probably make calculations until infinity with it. REALLY helpful. Sorry for my review being so short, there is not much more to say then how amazing this app is.

Yours faithfully,

Great the % key on main keyboard

Recently they listened to feedback and put a percentage key on the main keyboard by shrinking the zero key to normal size. This makes it an ideal calculator for everyday use BUT with a ticker tape history display too.

You can copy from tape to paste in emails etc, or paste into new calculations. Delete last digit took a bit of finding but it is there near the result display. Also press here to insert value copied from ticker tape.

Finally full scientific if you rotate to landscape just like the iOS app does.

It’s a calculator.

It works as a calculator, fine, but ads and other pop ups incredibly annoying especially after every calculation you perform. Deleted. The developer replied to my review so credit for that. I suppose I’m wondering why there isn’t a calculator on my iPad the way there’s one on every phone for free? Also once you produce a calculator app that calculates what further development do you need to do? Sounds like a way to generate more income. As others have said just charge an amount from day one and lose the adverts.
