Free to use for 7 days, then you have to pay to continue to use it? LMAO Yeah, no thanks! You do understand that there are other calculator apps out there that have the same functions, but they have a nicer interface, the layout is more in line with a real calculator, have only one small banner and, and are free to use, right? You can buy a key to lose the unobtrusive ads, but it isn't necessary to continue using the app. Pass. Uninstalling.

I really like how I can choose to control ads. Some of the calculating functions are not smoothly completed is why I held back on providing a 5. I like the look and menu options like sound, appearance, and history.
