What’s new
Version 4.3 · Updated May 6, 2026
In this version, the size of the font in the display area will grow or shrink based on the user's "Text Size" setting in the "Display & Brightness" section of the system settings. So, if you have your text size increased from default, you should find that the text in the display of the calculator will also be somewhat larger and easier to read. If you have the setting low so that your text tends to be smaller than default, you should find that the text in the display of the calculator will also be smaller and show more content on your screen. Let us know if the behaviour is not to your liking and we can tweak this behaviour in future versions.
