Good set of functions, however some perfectly valid expressions produce 'math error', e.g. xor function is not properly implemented

I loved this calculator until the Android 11 update. Now the bottom row of buttons are hidden under the home buttons. The calculator is useless now.

These new all-CAPS buttons are hideous, an assault on the senses. I love this app and I have used it daily for years. PLEASE put them back the way they used to be... There was no reason to change it.

I have been using this app for so many years. It has the ability to graph, solve equations, and also does unit conversions.

On long press the button 3, doesn't work for convert. I have also tried for the second method that hasn't worked. But the app the awesome. Please fix such issue. Thanks

There is a Big problem with some equation, lake the cubic square of 729, 1000 etc. These should give you exact number, but for some reason, that doesn't happen here. Fix Edited: still in 2025 and you have not corrected the issues.

Very nice calc. I think a old handheld solar powered casio calc i owned could do a hex to bin to oct in one keystroke. On this app conversions will occur after first entering and hitting the equal button..then hit the conversion button . This one does not appear to do one button conversion... wish a update could add that feature...enter a value and then one button push conversions could occur. Otherwise very nice calc and does need any permissions!!!

Great app, I've been using it for a number of years to my satisfaction. The only thing I sometimes miss are some options for decimal grouping, it would make the entry of large figures much easier. Another nice feature would be the ability to copy/paste from and to the input field.

This has been my favorite Android calculator app for years (hence paid for pro), until I upgraded to Android 11 today. Now, as mentioned by others, the bottom row is covered by the Navigation Bar, rendering the calculator useless. Please fix this issue asap! I have a screenshot of the issue of needed. Thank you!

Probably the best sci-calc app in Android. I used the free version for more than 5y. Finnaly I paid for this pro version.Thank the developer for developing such a great app! A suggestion: it would be better if provides an option for increasing the number of items in the history list cause sometimes 50 is not enough.
