good calculator, but some of the controls are a bit confusing. you have to put your phone on landscape for the variety of tools to show, and some tools are a but difficult to use, but math and numbers aren't my forté, so I would naturally have a worse time than most with this.

I use a calculator to assist with my budget. I have all my bills listed in a separate calendar app and cycle between the 2 apps multiple times to figure out my plan. Every time I cycle back to the calculator, there is a popup add. As I cycle multiple times in succession, I end up constantly clicking on ads. This quickly gets frustrating. I have no idea if the calculator works well or not because I spent more time closing unwanted adds than actually using the calculator.

no ads, no required internet (if you get ads, just turn off your internet/data), perfect calculations, needs literal inputs, little issue though. whenever I go into scientific mode, there is only the e button, and no E or EE button. this requires me to add an extra ×10^(number) at the end with each calculation that is very, very large. if there was just these two extra buttons, AND everything else, it would be a 5 star review.
