Monthly Fee for Ad Removal? I don’t think so.

Horrible experience. I absolutely refuse to pay a monthly fee, no matter how small, to remove ad’s from a Calculator app. I will look for an alternative that’s not as greedy.

Suggestion to the developers? We all know you have to make your money but, a subscription based Calculator app? You are joking right? The scripting is simple and the hardest part of making the entire app is drawing the graphics which can be done in a few hours by a digital graphics designer thats been behind a mouse for 5 minutes. If you want to charge a subscription for something develop an app worth charging it for.

Long time user but ads have become obnoxious

I could always handle the ads before, but now full screen (almost) ads come up between calculations. And the ad presence has increased. So I was willing to pay for the App to eliminate ads, but through the App I can only sign up for monthly payments, even though in the App Store there is listed an option for removing the ads at $1.99.

As a calculator it has been wonderful, easy to use, full function but not at a monthly charge.

Large letters

Being elderly, I appreciate the large numeral format. It has every arithmetic function I need plus some I have forgotten from HS.

Updated sept. 2017..switching apps due to intrusive ads, monthly no ad fee, not updated to work in dual screen mode with IoS 11 and stops functioning when ads sends in pop ups.
