Ratings and reviews

Love the RPN mode and the many useful features, like symbolic math and unit conversions. However, as of Feb 2025, it is unbelievably slow, even with the latest and fastest HW. It can't keep up with button presses and gets behind or misses presses. Perhaps it's only slow in RPN mode??

This calculator has all the features you will ever need, and also can be customized to your preferred expression notation, a feature very useful to avoid order of operations miscalculations. Yet the one feature I'm still waiting for is the addition of up and down buttons, as it feels a little sluggish trying to get to the right input box when working with fractions or powers with only left and right keys. Also it'd be nice to have new themes or an option to use a picture from the gallery.

This is simply the best calculator I have come across! The ability to handle fractions, roots and so much more, makes this a truly versatile calculator! The built-in constants and conversions are priceless! A most impressive power house! And a special "Thank You" to the developers who actually hear you when you speak! Great Work! Every new update just makes it more versatile.
