User Reviews

I really like that this calculator has 4 additional memory slots and that all stored memory values persist across sessions and are always visible. That means I can store constant values in one or more of them for easy selection and recall at any time. VERY GOOD! There does not seem to be a way to contact the developer or support though and the last update was over a year ago. Here are my suggestions for improvement. 1. Display negative values in red. 2. The fonts used to pack in all the displayed information are very small which makes it a problem for folks like me to read them. This is WAY MORE a problem for an iPhone than an iPad. So, see #3. 3. The "active" memory slot appears to be indicated by dark-graying that slot's entire display field. The memory values are always displayed in black so it's black on dark gray making it very hard to read the selected slot's value. NOT GOOD IN GENERAL. What I think would be much better is if just the name of the selected slot (MR, M1, etc) were in bold or green or whatever leaving the value portion of the memory fields a constant color (the current is OK) with positive values shown in black and negative in red.
