Reviews on Halcyon Calc for iOS
★★★★☆My favorite RPN calculator
I went to college in the late 80's with an HP-28S. I still have the HP calculator, and it still works; and I'd been wanting an RPN calc for the phone that was similar to that one. There are a bunch of HP-12-like apps, but this is the first one I've found that behaves similar to the 28S. Very happy with Halcyon Calc; I've been able to delete all the other RPN calculator apps that I've tried.
★★★★★It works better than I had hoped!
My HP 28S calculator (the best programmable scientific calculator ever built) is back! Thanks so much! I took a rather complicated engineering program from my 28 (which used some rather esoteric functions), laid it in, and it ran perfectly! Two thumbs WAY up! More if I had them.
★★★★★Best Calculator out there
Love how responsive Halcyon Software is to fixing and improving this software. My favorite change on this release is the long or 3D press to get the red shift key.
My 28S still runs perfectly but the battery door is so fragile. I can use Halcyon Calc all the time.
