Ratings and Reviews
Very Good Rendition of an 11C
This app works well and functionality is just what the old 11c delivered. It would be great if the copy and paste functions (menus and keyboard shortcuts) worked to copy/paste numbers from/to the X register. That way numbers could be easily brought in from another application and the result of a calculation could be copied and pasted into yet another application. As it stands, it is a pretty good app; this addition would make it great.
Hyp Trig Functions
The Hyperbolic Trig functions on RPNcalc11c (exactly like those on a "real" HP11C), ALWAYS treat the angle in radians REGARDLESS of the selected Trig Mode. This inconsistency can easily be accounted for while doing calculations but yields wildly erroneous results if one fails to do so. The normal Trig Functions work properly in the selected Trig Mode as should be.
bitPunch is to be commended for making this series of wonderful calculator apps available for those who don't have mobile devices.
seems to work ok, but screen is limited
Is there a way to show the history on the screen? One thing I like about my HP calculator is that it shows the buffer 4 lines deep. On a computer, I should have this option. In it's current state, I don't think it is worth $2.99.
With Family Sharing set up, up to six family members can use this app.
