Ratings and reviews

Brillant, and free, with lots of preprogrammed options. What would be beneficial would be the option to add fixed calculations of our own that could be recalled from memory by name. Remembering the figures, sequence, and brackets for a particular method can be problematic. Otherwise, not a lot of room for improvement.

Nice, clean and feature rich, but I would like to be able to edit the formula (without the need to go back with the delete button). E.g. I type 25x22+11+1, and I want to edit it to 26x22+11+1, now I have to delete everything except the first 2, to be able to edit it, and then I need to type back x22+11+1 again. Not very useful in these situations. Also, showing results live (without the need to hit the = button) would be better.

Good, but not perfect! Could you add the option, to automatically delete the last calculation after pressing the equal key - to start a new calculation (like the regular calculators would do). Instead of the AC key. It is super annoying when starting a new calculation and you are finding yourself typing your numbers into the text field of the previous calculation.
