Ads for calc blows

It is ridiculous that I have to have ads to use a calculator! This is more of a complaint on Apple than this app, however, as Apple got rid of the free calculator that used to come on the iPhone.

Piece of *******

Adds crash it every five minutes and you can’t close them even when their done play, app is trash

Horrendous

You will be bombarded by ads after every calculation, it makes the experience horrible. I would so much rather have a static banner ad at the top then have to wait for the video ad to play every single time

The ads are ridiculous

Full screen unskippable ads will interrupt your every calculation, no matter how basic. Genuinely annoying, would recommend one of the millions and millions of other calculators in the world over this one.

Absolutely riddled with ads

It plays a full screen ad WHILE typing out your equations.
