Ads are prompted upon opening the app?!

I BOUGHT this app so I could make calculations quickly WITHOUT being interrupted by ads. However, very often I have to click out a pop-up window that is prompted whenever I start the app. Absolutely ridiculous for a app I PAID for...

Apart from this atrocious marketing scam, this app isn’t even compatible with iOS 11’s multitasking!

There are a lot of calculator apps for iOS which actually function with iOS 11 and don’t incessantly advertise at you once you bought it so steer clear of this rip-off.

Note to Developer: I’ve seen other reviews complain about these pop-up ads on the paid version but you seem to insist that they must still using the free version, this is NOT the case. On the PAID version of this app, you have programmed it to often times create a pop-up (not a banner) when opened to advertise your companies products. It’s dishonest and offensive to your customers whom are told they are purchasing an “ad-free” version.
