What's New in Version 4.5
Full support for macOS 10.13 High Sierra.
Completely rewrote the display code. Many exciting things to come later which are now possible because of this, but some changes today!
You can now drag values to and from any line of the display and the registers / stack window.
You can now adjust the size of the digits in the display, and make them much bigger or smaller.
You can now use a space for the thousands separator.
Hex, octal, and binary numbers are now grouped using spaces on the display.
Added links for downloading the manual to the Help menu.
Added a arbitrary base "Log N" button to most of the advanced layouts.
Added a variety of new digit styles.
Fixed a display problem with the tape and the "Show implied parentheses" option.
Fixed a problem resetting user layouts.
There might be a small game in the About screen too.
Very Close to Perfect!
Its stable, feature rich, and very configurable (aesthetically pleasing too). The developer never fails to respond quickly to questions, suggestions, or technical requests. If all applications were this well executed, life would be much better than it is. Buy it. I’ve never regrettted doing so.
Awesome - and that’s just the game in the About menu!
Wow! Best calculator for macOS I’ve seen, now better, now with an outstanding game. Fun if pointless. But the programmer opened up the Unity colliders, wireframes, flame particle physics. I”m 10 minutes late to my next thing because I couldn’t stop playing, throwing bananas and calculators at the logo. Unity for a calculator easter egg game! Wow!
Best Calculator App Ever
This is my goto calculator, I can’t imagine it any better, but the developer is always improving it. Worth the money on macOS and iOS!
