Used this app for years. Probably close to a decade. Even through being a physics major in college. Absolutely loved it. New update is terrible. Switched to a weird font trying to be aesthetic instead of a normal, highly legible font. And the new button layout/sizing is a downgrade- not as functional. Not sure why any changes were made. With that being said. Will continue to see if it grows on me- I owe it to this old friend. But really wish I could revert to previous version...

Sorry, I had to tweak some layouts to make room for the new functionality and keep things grouped properly. The font you're referring to was an "option" before, but that posed issues as all fonts have different stroke-width, baselines...making it hard to support all layouts across all devices, etc. I will explore more font options in the future.

What was already fine became excellent!!! Constants with latest CODATA 2018 official values! Click sound perfect now! Great! The only things yet to fix are in the Menu: the "Help" button and the Web link in "About" keep not working for me! Edit: they simply do not work. As they're touched, nothing happens. The E-mail link in "About" works well, immediately runs the mail app; the Web link does nothing, same as the "Help" in the Menu.

Hey John, Thanks so much for the feedback and review. ** edit ** Ok, thanks for the details! I'll look into what might be causing that.

My go-to calculator for several years. Basic, scientific, and programmer layouts with algebraic and RPN modes. Tons of functionality. A big screen that helps you with more complex calculations. A huge stack - up to 50 deep - more than you could possibly ever use. All this is wrapped in your choice of terrific themes that make it a real pleasure to look at, too. Zero internet permissions! The only thing I would change is to put this gem in the hands of more people. It's a great calculator!

Sam, thanks for the support, awesome review and 5 stars!!! You are right on the 0^0 and I usually I look to wolfram for the most appropriate response, which is undefined in this case. One day, I'd like to add more specific errors (undefined vs infinity, etc.) - Sam

What's new

Android's best all-around calculator just got better! Equations can now be edited, and results are calculated in real-time. Plus, lots of other improvements.
