It’s one of the best calculator app


I’ve used this calculator for such a long time, never using iPhone’s calculator. But will you please stop prompting me to do in app purchase. Whenever I click never to show again, it never stops to prompt me with the same in app purchase.
Please stop please stop please stop!

No doubt, the best calculator of iOS
