Not s real 16c. Hex magnitudes are limited to FFFF. I bought it to escape that limitation in another calculator and was disappointed. I'll delete it. Should have read the reviews. I made the mistake of trying it again on my new ‘phone. There is no way to close it on my XR. There is no drag- up bar, and the app will not rotate out of landscape orientation.

Good but poor readability. I loved my HP 16 C. (I wonder whatever happened to it.) This app is an inexpensive emulator that does a good job. My biggest complaint is poor readability of the yellow function labels, especially in the central area. Please get rid of the background color gradient!

It will do more than 16 bits. Been looking for a 16c since the old app I have was never updated to iOS 11. Looks like it works in two minutes playing with it (and I do have a real 16C at home). To respond to an earlier review... it will do more than 64 bits. Go to decimal mode, enter 32 and then do f wsize. That sets the word size. It will even do 64 bits, you have to scroll the display with g arrows (on the STO RCL buttons). Not convenient but it works and matches what I recall of the 16c (I have not used that particular function in years). The dots on either side of the h (or b, d, o) indicate that scrolling is needed. Thanks for the app, now I can finally upgrade from iOS 10...

Accurate but needs UX love.... UPDATE 190808: Dev said they'd fix readability but no change _many_ months later, support seems lacking. shame too, had potential. --- It's a surprisingly accurate 16c emulation (though I've found a few minor issues). Alas, color of keypad "shiny" background towards center makes yellow labels almost unreadable. needs a darker background with more contrast. Also not sure email sent to support regarding bugs is getting through, no replies received. In general decent solid emulator -- with some UX tweaks and a few bug fixes it would earn 5 stars!

Not the 16c! (Fixed). The developer has fixed this issue and everything seems to be working. Original Review: I bought this for the programmer’s tools like hex to decimal, binary conversions, etc. This app does not not have any of this. Instead, it the HP11c engineering calculator. I have both the real HP16c and HP11C, so I’m sure. What a bummer! IT IS NOT WHAT IS ADVERTISED!!!

Hard to read. Can’t read the yellow labels. Really ruins an otherwise good app. Five stars if they fix it.

has an AND problem. everything went fine until I tried to AND 0x72 with 0x3f Th eresult was 33 not 32 tried using binary and got the same results.

Great HP16C emulator. This is a great HP16C emulator — I use it all the time — the only suggestion would be to make the chars easier to see and maybe to have an original HP calculator skin — it would be 5 stars if the kbd chars were easier to see — but it is a great calculator :)

Works a charm!. Runs my old (not very mind taxing) HP16C programs fine. Function labels could be darker. 0x0c should be 'C', not 'c'.
