Great calculator but since the new update the small results' panel under the big input panel (the topmost panel) has white text on a white background making it hard to see. Update: The developer has already been in touch (within a few hours) and says this issue will be fixed, so will bump my review back to 5 stars for a great calculator and great service from the developers.

★★★★★Regina Litman· Dec 16, 2025
Very easy to use, and it includes many functions. Issues I had earlier, Plot not working properly if function starts with a negative value and inability to read the Settings page and error messages, have been fixed. I am also an iPad user, and I wish you had a King Calculator for iPad, too.
