This is a great calculator with lots of features and configurable standard vs scientific input format. I’ve used it for years. I am, however, not happy I had to pay for full version to eliminate advertisements that weren’t originally that prominent. The ads are consistently now a banner of lingerie photos, and it feels like extortion to pay to get rid of that.
Developer Response
Thanks for the feedback. In the next release, let me add a user setting for reducing mature/ sensitive ads.
